Dormitory units: Abetenim, Ghana
Ticket number: #489236534
DESIGN STATEMENT :
The design of our project is based on our understanding of the guide masterplan for the campus: a forest landscape design with minerals buildings that stand out of the trees. Our concept for the dormitory units is to design two identical entities facing each other and creating a central courtyard. This sheltered area is used as a buffer space from the public campus area to the dormitories, where students can huddle together.
Each part on the building is composed of two dormitory units for 24 students each, a toilets unit, a baths unit and an open sheltered living room. That extra space offers a secondary intimacy filter from the courtyard to the sleeping units.
Thin walls that close the toilets and baths units are made out of adobe bricks, with light and ventilation openings. Rammed earth has been chosen for the dormitory units to improve the indoor coolness and the structure bracing. A white corrugated iron roof protects the all building against the rain and creates natural ventilation. A false ceiling covers the sleeping units, in order to reduce the noise and heat impact of roof.
The framed structure is made out of hard local wood. Its design is based on the sleeping units’ dimensions. It both maintains the textile and wood partitioning panels, the false ceiling and the roof. Its poles are fixed to the foundation blocks to prevent the wind to tear the roof.
Rain water is collected through pipes to a container in the bath unit and to a central pool in the courtyard. It is used for showering, then filtered and used for watering the surrounding plants, but also to cool the air of the courtyard sheltered space, which is designed to be a big shared living room for the 96 students.

Cafeteria in Abetenim Arts Village
Design team : Raluca Aldea, Ana Marchidan (Romania)
The program that we decided to work on is the cafeteria. The functionality of this program is complex, the main hall having the ability to serve as a multifunctional space for different activities, such as dining, school plays, workshops, or even special events.
The focus of the project is the courtyard space, which defines the ensemble and gives it a special ambiance, while the nature breaths through. MATERIALS AND STRUCTURE Locally provided materials and labour had a very important part in designing this project. The intention was to use the usual methods of construction in order to obtain a different solution, without ignoring the ghanaian culture and traditions.

In Abetentim, Ghana
Design Team: ANDREA SUARDI (Italia)
The design should be always thought for the users thus it aims to look new and appealing but familiar to the locals. Along this is crucial to offer the highest possible comfort without consuming energy, therefore the shapes modify adapting to solar radiation, natural ventilation and natural lighting. Materials inspire the design defining massive and light parts, the former mainly made by earth, the latter by wood. The design responds to the actual needs for instance the structure increase, decrease or turn columns based on force flows and on the capability to resist to the heavy storms of the area, moreover it integrates other functions as windows/louvers and shelfs.
The space here is doubled having a protected area around the building which serves as a buffer, as distribution system and if combined in series defines outdoor rooms suitable for different purposes. This exterior space is planned to be simple but engaging for kids while the interior aims to be as functional as possible. The combination of multiple labs gives the possibility of reducing cost (-20/30%) because it is reduced the roof size in comparison to the interior useful surface. The overhang (thus the price) can be reduced in accordance to the specific site morphology specially accordingly to the trees position.

"In the Ashanti culture, Tuesday is a lucky day. A child born that day will be named Kobéna and will be in luck"
Design Team : Delphine COURROYE - Delphine DION - Marcel MALHÈRE - Aurélien MÉCHAIN / Collectif IN SPIRO (France)
The KOBENA project focuses on building class unity because it is the first essential element in the development of the campus. The study of Ghana's Ashanti civilization through its traditions, knowledge and materials has identified several distinct main ideas to which the project should take direction:
• The project integrates and revisits local materials. Rammed earth, adobe and thatch are suitable for the local climatic conditions by reusing traditional methods. Structural possibilities using bamboo will allow the project to be included in a government initiative that targets sustainable development via the use of planted and cultivated materials.
• This project follows a gradual constructive process with long term objectives that can develop in parallel with funding. From the first stage of construction, the school will operate independently, offering two study areas on two levels as well as a covered area. Topped with a common roof, half of it will serve as a shelter before becoming a new class unit at the next step.
• Foundations are topped with rammed earth walls and adobe. Internal Bamboo spandrel extends to the roofing framework built from the same material. The roof is thatched and continues outwards so as to create a playground that will protect from the sun and bad weather. The costs of a unit include a class and the roof of the next class.
• The traditional gabled roof is also to double the floor space by creating an additional level. This extra space creates a different atmosphere and offers other possibilities (individual or group studies...). Its lighter and wider angle allows the general circulation.

Design Team: Carmelo Bustinto, Tiziana Firrone, Eleonora Montalbano, Federico Napoli, Gloria Oddo, Filippo Palazzolo (Italy)
The building consist of a laboratory classroom, an external path on the south facade and a patio allocated in a 20x10 meters rectangle, oriented along the east-west axe.
The structure rests on a continuous foundation made by stones and lime, with wooden beams swallowed inside it, connected to the vertical wooden supports of the roofing.
The foundation is made within a 40 cm deep section excavation and it rises from the ground level of 45 cm more, in order to distance the walls from the soil.
The lab wall structure is made of raw earth reinforced with coconut fibers, raised up with Atakpamé technique, and occupies a rectangular area of about 76 m2. The wall is stiffened by raw earth buttresses, intersecting the longer sides of the building and generating niches both inside and outside of the perimeter walls of the laboratory. The interior alcoves host some of the laboratory furniture (shelves, racks, cabinets), while the external ones house the benches overlooking the outside corridor. The perimeter walls rise 3 meters high.
Terracotta pots, transversally cut and inserted in the thickness of the perimeter walls, pierce the walls with circular holes, letting the light and the wind enter inside the laboratory.
A pitched roof covers the outside corridor and the patio. Its structure is made up of corrugated metal sheets and wooden beams coming up from the wall and anchored in the foundation. The space between the vertical walls and the cover ensures the ventilation inside the laboratory. The lower part of the roofing is on the North side, in order to divert the hot and dusty wind of Harmattan, coming from North-east. This is also the reason why the East façade has no openings and rises almost to the roof.
The South façade is sheltered by the corridor and the patio, appropriately shielded to protect from the summer rains brought by the Atlantic monsoons.

Our classroom project aim to satisfy three major points.
Acoustic and thermal comfort
Economy and use of local materials
As regards the livability we made our project keeping in mind that a classroom must be simple and with proportionate shape, so would be adequate to receive a a not excessive number of people. In this way learning is not compromised by overcrowding.
The class is rectangular with a different height, from 3 to 3.8 metres, in this way there is a good air exchange, also thanks to several opening on walls.
The air enters from the lower openings and creates a microcirculation rising throught higher openings on the wall and between bamboo canes below the roof.
We have choosen a particular type of corrugated sheets for the roof, because it's made by several layers designed to offer a great thermal and acoustic comfort. This was the first goal we had in mind because the noise of pouring rain over a simple metallic surface could be really annoying.
This solution has these benefits and it is also on budget, expecially providing a big order to cover a large number of modules. We estimated it will cost around 16$ per square meter.
Wall are made with rammed earth techniques, and a foundation with a curb are 50cm deep.
Roofing structure is made with local timber beams as well as shading blades for doors and windows.
This simple shape permits a rapid construction and shorter wall are intentionally without openings, in this way several modules can be assembled and form a courtyard.

ENTRY # 492608304LAYEARTH: A Secondary School Classroom, Abetenim Village, Ghana
Design Team: Jacob Van de Roovaart
(Designer/Drafter, Reiss Design Studio, CA)Project Description:
LAYEARTH seeks to combine simple construction methods with local building materials to create a rammed earth classroom composed of unique layers. The design promotes a comfortable learning environment through understanding Ghana’s climate and culture. A bamboo layer, or screen, drives the aesthetic of the classroom and helps to not only shade the walls from the sun, but also to define the outdoor space. From the exterior, one can immediately observe the layers of depth that the bamboo screen provides at both the circulation corridor along the eastern and western sides and through the large covered outdoor entry, meant to act as an extension of the classroom. The covered outdoor space is essential because it provides an opportunity for students to study in a dynamic environment with multiple learning spaces. The offset bamboo layer is critical in regulating the internal temperature of the classroom because it prevents direct heat gain through the walls. Special attention was also given to the layout of the classroom clusters: by shifting adjoining classrooms, natural ventilation can occur in multiple directions. Inside the classroom, a full height jali wall greets students with a wash of light, inspiring them as they begin their days. The LAYEARTH classroom measures a comfortable seven by ten meters. The proportions of the classroom are ideal for allowing the teachers more proximity and control over their students. Windows with operable louvers on the north and south elevations encourage natural ventilation and daylighting while upper roof louvers on all sides vent hot air. Construction Methods & Cost
- Trench footing around the perimeter which acts a strong base for the rammed earth walls. The footings for the columns are multi functional in that they support the columns and also provide a bench for the outdoor classroom.

RUBIK’S STAFF QUARTERS
Design Team: Richard Hawkins (Architect), Kwesi Acquah-Hayford (Architect), Tono Rodriguez (Architect), Mohammed Vacchiyat (Architect), Matthew Redding (Architectural Assistant), UK.
RUBIK’S STAFF QUARTERS
In the Ghanaian Akan tradition “he who does not know can know by learning”. This is represented by the symbol called ‘Nea onnim no sua a ohu’. This symbol has three main segments which in three dimension corresponds to the Rubik’s Cube which we have used as the starting point for our design. In designing the Staff Quarters as an educational facility, we have reinterpreted the ‘Nea onnim no sua a ohu’ symbol with an aesthetic, modern, scalable, flexible and minimalist twist.
Each ‘Room Unit’ forms a separate cube with one of four functions: lounge; bed room; kitchen/Bath; and open courtyard. In line with the Rubik’s concept, each is arranged in the three by three grid of the ‘House Unit’ with the living room forming a double height cube, emphasising the importance of this space. The house can be changed by adding or taking away Room Units. House Units are arranged in the three by three grid of the ‘Square’ which is designed to be constructed in phases.
The “Courtyard” is embedded in Ghanaian architectural heritage as both a functional and transition space. This motif is used in the design both in the ‘House Unit’ and the ‘Square’ with mature palm trees salvaged locally providing shade. In addition, the ‘square’ is intended to be used for community meetings and family events. The ‘House Unit’ courtyard exploits the tradition of perforated enclosing walls giving glimpses between the two courtyard spaces at the same time representing the beautiful decorated houses of the important citizens which typified the traditional Ashanti house type.
The completed staff quarters would consist of four ‘Linked Squares’ accommodating all of the staff.
Foundations are trench filled with local rubble. Walls and floors made of surface treated well compacted rammed earth, and corrugated roofing sheets are supported by locally sourced timber purlins and rafters.

Abetenim Earth school classroom
The Abetenim secondary school gives children the chance to pursue their studies after graduating from primary school and thus increases the educational opportunities in the village. The project of the classroom type is inspired by the idea of community and influenced by the traditional courtyard-based construction of the nearby city of Kumasi. Each building module contains three classrooms and a social covered outdoor space. Groups of seven modules are arranged in a U-shaped configuration around a common courtyard. All existing trees should be kept whenever possible. Each module is oriented so that the social area faces Northeast and the classrooms open to the fresh breeze coming from Southwest.
The project makes use of local resources like rammed earth, hand-made adobe bricks and wood beams. The base of each building is made of concrete and corrugated zinc sheets are used for the rooftop. The passive solar design ensures natural ventilation and the overhanging roof provides substantial shading, which help to keep adequate indoor climate. With a capacity of around thirty students, classrooms are 9 meters long and 4,5 meters wide, with three doors and three windows distributed lengthways. The doors are made of wooden frames and a locally produced bamboo mesh coloured with different Ashanti patterns that make each classroom unique. There is a central corridor with open ends, from which it is possible to access all the classrooms. When all doors are completely open, classrooms seem to merge in a single common space. At one end of the corridor students can climb up to a suspended rope net. Tables and benches are available in the social space.Budget:

Abetenim Community Secondary School
Cameron Deynzer, Gwena Gilbert, Olivia Collinson and Olivia Owen from Jasmax ArchitectsDesign Summary:
The idea of designing a classroom, a hall, a dormitory or even an entire school offers more than an opportunity to design a space. It operates as a device to enable, condition, structure or restructure human experience. The concept behind this design is to demonstrate how architecture and construction, when driven by human issues and ethical practices, can foster sustainable social development.
We move beyond designing a classroom and think about how the building can have a deeper meaning. What if, through the construction of this built work, we can harness local communities through direct employment and upskilling? Local tools, resources and input will give this classroom and school a much more deeply rooted meaning as in sits in the landscape for many years to come.
The staging of the classroom unit encourages multiple uses across the site as funding becomes available for building. For example, the roof can be constructed separately to act as a sunshade, providing an outdoor classroom or respite from the heat.
Our design aims to create a better lifestyle for the users rather than just a teaching space; a sheltered, outdoor orientated building that flows seamlessly between inside and outside, and one that has a positive and meaningful contribution to the environment.

IT TAKES A COMMUNITY TO RAISE A CHILD
“It takes a village to raise a child”
Our proposal approaches the challenge from a village scale rather than looking at the design challenge from a micro scale of the building typologies. The team proposes to re-think the tentative master plan because of certain design
considerations and urban strategy.On a village scale, we have positioned sporting facilities closer to the site boundary/road to aid community engagement.
“The hall” we believe can be “multi-functional” with a possibility for it to be an assembly/school events hall, cafeteria, community hall and a sports pavilion. It’s positioning will however allow the community to have access to the sporting facilities without interfering with the normal school activities. Also, zoning the sporting facilities away from the staff area will also allow for privacy and avoid potential noise pollution from the sporting area generated by the students.With an understanding that social architecture doesn't have to be mediocre because it’s low budget and locally made, we propose a new master plan using a different cluster concept and approach since the present proposal is still tentative.
This will not only make the idea of modular building easy but it also begins to suggest a better strategy for incremental replication. We propose a master plan adopting the beehive concept for its layout and this is a module that has been tested across the entire master plan with all typologies thereby creating a great sense of territorial coherence, which knits itself with its immediate landscape of palm trees and vegetation. We propose to also have a flexible cluster concept that can develop into a series of angled interconnected enfilades of courtyards creating a series strong axis across the entire campus. The cluster concept has however allowed for a variation in size and positioning thereby allowing for an interesting juxtaposition geometrical scale and function.

THE VOLTA SCHOOL
Design team: DANG Thanh Hung, BUI Ngoc Tu, HO Trong Nhan, NGUYEN Tai Ngoc (Vietnam)
The school is named by the name of the largest man-made lake in Ghana - Volta. It is called by the Volta School in Ashanti Region of Ghana.
The building typology collected for this project is the classroom. On the site, there is a total of 13 units of classrooms organized alternatively with the existing vegetation. Each unit contains two classes in which each class has a capacity of 42 students.
The major scheme for the master plan is to leave the respect for the current natural conditions of the site entirely. Particularly, two large areas of palm trees will be saved for remaining the moderate atmosphere and coolness for the whole site. Besides, the domestic walkways are kept mostly to become the main circulation for the users. Hence, the area of vegetation in the middle of the site becomes the central courtyard for all students and staffs of the school.
All steps in the construction of a typical unit and other blocks are based on three basic factors – affordability, possibility, and environmental efficiency. The materials used for all architectural elements of the design have resources from nature and are entirely available on the construction site and neighborhoods such as earth for foundation and insulation walls, palm wood for door/window frames, and palm leaves of roofing. Furthermore, all traditional and regional technologies in construction are applied besides the environmental strategies to ensure that they are familiar with the local labors.
To deal with the vulnerability of climatic conditions to the buildings in this area, the passive design strategies are thought and used effectively to reduce impacts of the weather on the buildings and remain the comfort for the people, especially in hot season. These environmental solutions focus on optimum of natural ventilation for both cross- and stack- ventilation by the large overhang of the corridor, high palm leaf roof, the appropriate room depth and the openings designed for all walls. Additionally, they allow the penetration of diffuse natural light inside the building to provide a good visual environment for the students, however, still keeping the direct sunlight outside from 10 am.
For the hot dry places, the vegetation is very important to preserve the humidity and the coolness. So, an effective simple method is used that the rainwater will be reused and collected by the system of biological gutters of pebbles. This system conducts the rainwater going around the courtyards and lawns, and providing water slowly for earth and plants. By this way, the maintenance of the vegetation is very affordable and a decrease of labors.

Two Walls: Classrooms
DESIGN TEAM: Jay Ding (Canada/Taiwan)
Two Walls is a solution and vision of classrooms for the upcoming school in the Abetenim Village of Ghana.
To deliver a flexible, sustainable and meaningful design solution for vernacular architecture, we need to take great consideration and be extremely respectful to the stories and people that we are building for, as well as the history of the site environment.
Also, it is the architect’s responsibility to create a design solution that will be sustainable for the locals. Sustainability should not only be reflected in the use of materials or construction methods, but it should also be demonstrated as a creation of pride of the locals. With their own pride, the local users and people will maintain the product in a sustainable manner that no architect or designer can create.
Hence, the main notion of Two Walls is not a solution that the designer came up with. Instead, it is a solution that is created from the existing elements of the site. These elements are not just the sun, rain, wind or water, but also the lifestyle, art and stories of the locals.

The design of a classroom block for Abetenim is driven from extensive experience of education buildings in West Africa. The concept is of elegant simplicity: Using compressive material appropriate way to create a high quality internal environment.02. Estimated Budget: Roofing: 1500 $Walls & Vaults and metal joinery: 3500 $Foundations & Ground: 3000 $TOTAL Estimated Cost: 8000 $
The two classrooms are formed from six brick domes linked with arches. Each dome has an oculus allowing natural light to flood in from high level. This also enables effective ventilation to the classrooms. Contrasting the domes, the lightweight bamboo canopy shades the masonry beneath thereby maintaining a pleasant indoor temperature.
Flat walls at either end of the classroom provide ample wall area for blackboards and presentations. The numerous windows with shading shutters control the light and allow plentiful ventilation. The insides of the domes are painted white to reflect light to create the even lighting conditions essential in a learning environment. Between the walls shelving and storage for educational materials is stored. Showing again the design is driven by the requirements of a classroom.
The domes, piers and foundations are of locally fired clay bricks so is the ground of the pergola. This limits the need for reinforced concrete to the inner ground in order to assure maintenance. Roof structure is of bamboo. The oculi are constructed from oil barrels. This reusing of material saves on cost and demonstrates the potential beauty of recycled materials. It is considered that the construction technique is very relevant to the area and could replicated on a number of different buildings.

Inspired by Kente cloth patterns and the human hands that weave them, the design of Handmade school is aimed at providing a place of both nurturing and encouragement. While the perimeter buildings surround the entire complex embrace, the innermost buildings tentatively reach out beyond the implied boundary, and into the surrounding site. Hierarchy is introduced both through programming and roof height: assembly spaces feature taller roofs and clerestory space while general classroom spaces are housed under shorter roofs. Finger-like interstitial spaces between the buildings act as outdoor gathering spaces and playgrounds. Air freely circulates throughout the structures by means of staggered brick walls, wooden partitions and clerestory windows. Compressed earth blocks are enhanced with surface articulation using formwork fabricated from sheet metal and plywood. Wooden partitions act as a screen, partially blocking the view while allowing air to move throughout the rooms. Open air trusses also aid in allowing light and air to circulate freely.

The Learning module of rammed earth
Architect : Site-Specific Co.,Ltd.
Principal-in-charge: Chutayaves Sinthuphan
Project Architect: Buttriya Ruamthamarak
Project Team: Suthisak Suwannarach
Even though ‘earth architecture’ is one of the most environmentally friendly types of construction in existence, still, there are rooms to push the efficiency beyond the current boundary. And one must look at the architecture as a living eco-system, not just an individual building.
Starting with the re-worked masterplan for the school campus, we are proposing a new organization system to improve efficiency between each zone of the school. We took the existing masterplan and re-organizing it so that the tangent zones are related in term of usage. And this will allows that construction and management of the infrastructural systems such as water, waste and electricity to be at optimum efficiency.
The school buildings are conceived in modular system. Each of the modular is a curved ‘Y’ shape in various configurations. This allows the school campus to be constructed and expanding continually. By connecting each different parts to one another the school can be expanded as necessary at the same time the buildings can be adapt to different usage as the school is going through its expansion.
The module is constructed of rammed earth, palm wood and bamboo very easy material to find locally. The wall is made us of rammed earth, while the palm wood super structure and bamboo lattices support the roofs with waterproofing layer under the lightweight soil mixture. The sloping green roof also gives maximum efficiency in term of energy consumption and land usage. The roof can be used as an outdoor amphitheater, classrooms, food garden and playground.
By configuring the school building in this manner, the courtyards are created and this courtyard can be adapted to create large scale assembly hall in the future.

DESIGN STATEMENTFollowing the idea of architecture as a collective praxis driven by the need and wish for it and the
power of fulfilling the desired architectural dream our JSL Team suggest following design concept
for the competition ‘’4th Earth Architecture Competition, Designing a School for Ghana’’.
We have chosen to start with the basic module of classroom for children of ages 12 to 18 with
integrated semiopen library and social space. Our design offers a possibility of different uses of
the proposed module as well as the different multiplication possibilities in order to meet the need
of possible budget and functional modifications of the existing master plan.
Construction of the module includes reinforced concrete footing stripes over rubble trench and
reinforced screed floor 4cm thick (1 cement : 3s harp sand reinforced with a wire mesh) laying
on crushed rubble layer, reinforced rammed earth wall 30cm thick (reinforced with 5% of
cement), wooden roof construction laded with corrugated zinc roofing sheet is laying on roof ring
beam, windows and doors openings have wooden frames (windows are jali wooden windows
situated on the west ). The addition to the main construction is a double facade made out of the
knitting plastics (reused plastic bags).
(1) Foundation and screed floor 350 $
(2) Walling, Doors, Windows 3950 $
(3) Roof construction and double plastic facade 3700 $
SUM :8000 $
Using local materials and taking care of solar energy design , with the focus on sustainability our
proposal focuses on creating a functional, pleasant, inspiring and effective learning environment
which is intersected with semiopen interaction spaces designed for sharing knowledge, relaxing
and having fun.

ENTRY #512712099DESIGN STATEMENT
The proposal is about one unit of a CLASSROOM MODULE.
The main design is born through a simple aggregation formula of interchangeable modules, a patio is shaded crease. This space is cooled by air circulation and protected from the North.
The individual modules will have a double skin that have a strong identity with the traditional Ashanti houses. The double skin also has a threefold function: heating protection, circulating air flows and gradual protection of individuals.
The walls will feature a double materiality. A main rammed earth mud wall. And a second one defined of pressed bricks. The bricks will be placed more or less separated to let inside clarity, sound, shadows, privacy (functional item) pass, and design the different symbols of the Adinkra alphabet (cultural and social item).
PROPOSAL SITE PLAN
The proposal of the site plan creates 3 types of resting places: two outside places (one central and two lateral areas), and 6 patios (covered areas), that connect the CLASSROOM MODULES.
Considering the point that in the tropical climate the best orientation for housing, is to position them with the long side oriented to the East-West, we redefine the original site plan of 10 classroom module aggregation.
In our proposal each unit will be oriented E-W
The estimated budget includes materials and labor, excluding the land value and the specific training on building systems. The final Budget will be over $7.173,56

ARCHITECTURAL Design The design of the cafeteria is based on a modular unit which is repeated throughout the design. The modules are independent structures, allowing for a step-by-step development of the cafeteria.
The cafeteria can therefore grow along with the school to adjust to its number of students. The modular parts are connected by ‘corridors’ that visually and functionally bring the modules together.
The modules thus do not remain independent structures but become elements of a greater structure.
In order to obtain a comfortable indoor climate the standard module is conceived as a ‘box within a box’. The outer layer shelters the inner part from rain and direct sunlight. The inner layer, made up of thick rammed-earth walls, works as a heat buffer that helps to stabilize the indoor climate during the day.
The modules are arranged step-wise so rainwater can be collected efficiently. The corridors extend beyond the height of the modules so they can serve as ‘chimneys’ to enhance the effect of natural ventilation and allow daylight to penetrate the inner parts of the building.

Classrooms in Abetenim, Ghana
It takes a whole village to raise a child, it takes a whole village to build a school. All children should have the right to go to school. A place where he enters in order to be instructed. Then one day, he left his school, therefore ready to face his future, emancipated and confident.
With two odd facades, making up an L-shaped structure, the project recalls an open book. "The knowledge book". The monolithic facade protects from the dry and dusty wind and reveals the institutional function of the building dedicated to education thanks to a pediment as massive as welcoming. This is the main entrance of the building, which serves two classes of 4.5m x 9m each. While the second facade is thin and slender through a rhythm of black steel poles on which the roof overhang is sited. This is a breezeway shelter from the sun or rain. Each class consists of 15 desks that host 45 students and a teacher placed on the platform with a blackboard.
The facades are dissimilar, but they are nevertheless coherent in their context and in the modest use of materials, thus unifying the character of the building. The actual urban context is a composition of rectangular patio houses with a facade quite closed to the outside and an open facade that overlooks the courtyard. The traditional Ashanti buildings have the same typology with posts and courtyard. The project perpetuates this urban language through a mirror game of 4 L-shaped buildings (BOOK) together making up an ensemble which is clustered around an inner courtyard. About materials, the project emphasizes the use of local resources and materials, with an obstinacy for earthen construction techniques such as Atakpame (COB). The CobBook School is a crucible from where tradition and future merge together : preserving the heritage of Ashanti culture and adapt it to the world of tomorrow.

School in Ghana in our opinion should focus the most on the best educational conditions in hard enviroment. Our design modifies classical funcional class plan - rectangle - to another - circle. This intervention provides better distance from last bench to board. Each row of benches is situated on platform - first row is the lowest, last row is highest. This enables better view for every student. Circural plan also helps with fitting in more students on small surface. It is more convienient for kids as well as for teachers - they can see everone and have more control over them. This arrangment provides better acoustics and open discussion opportunieties for students.
Design in specific way connects classroom building. The look of traditional african houses inspired us to trasform and connect it. This prodecure causes look of the wave and binds together each building to make common area. Common area in front of classrooms is very important when it comes to building social contacts. People can spend the break together on talking, playing or simply sitting in shadow avoiding the heat.
The material used on roof is thatch. It is very effective in many ways. It this climate pouring rains are everyday atmospheric phenomenon. Thatch mutes the noise from the rain and don’t disturb in guiding lessons. It has more advantages in comparison to corrigended sheet. It looks better, provides better air flow and is more friendly to the enviroment.
The material used to construct walls will have to be pressed brick made out of local materials such as mud, sand, soil with a little addition od cement. It is very simple to produce and does not require specialistic machines.

Learning Pavillon: Classrooms Typology in Abetenim, Ghana
Design Team: Alessandra Renzulli, Architecture Student (Italy)
My design advances demands on the follows the local traditions. After analysing the local typology of architecture, the meaning of Adinkra symbology and the different rural material available on site, I have choosen to pursue my personal project with the configuration of classrooms.
Each complex includes ten classrooms with one common hallway of connection, set along the same inner perimeter, surmounted from an unique covering and connected by the external of two access points and two secondary ones to reach the specular gardens. Each classroom, is design for twenty students, which encloses a different typology in learning from a simple lectio frontalis to another one more collective.
The construction is placed on a cement concrete basement beyond its outer limit overlooking a raised cover, built with wood beams and metal sheets, supported from a net of mesh pillars and characterize by an inclination due to create an internal impluvium for draining water in rainy periods. The surrounding walls are wholly in earth and realized, according to Rammed Earth’s method, except for the walls of the external perimeter in which exists a studied texture in guaranteeing better internal conditions of drightness and ventilation.
The whole project is established on full respect of traditions, and for this reason it supplies a planimetrical proposition. Linked to Adinkra symbol of “support, cooperation and encouragement”, suitable terms founded for students’ formation with coverage in readjustment of the local building system, not only throughout the usage of rural resources, but even with respecting the home shooting at courts, one of the most utilized typology housing and preferred by the village itself.

DESIGN STATEMENTS :
The project tries to find a new way to use local materials through a contemporary architectural design. Whether in the form or in the usage of the earth, our aim is to create a new perception of this material.
The unit is basically divided into two volumes. The first one, on the bottom, is a solid block made out of earth and constitutes the living space. On top of it, the other one is in wood and procures a climate protection. These two volumes work together to provide a spatial quality and a maximum comfort to the children.
The northern and southern walls are the bearing walls. Made out of rammed earth, they are opaque in order to protect from the Harmattan wind and the solar radiation. The western and eastern walls are widely perforated using Compressed Earth Blocks (CEB) to provide natural light and ventilation.
The wooden upper volume acts as a thermal buffer. When the corrugated iron roofing heats up under solar radiation, the stored heat spreads downward. To prevent this heat to reach the classroom, the wooden volume is widely opened on all its sides. The hot air stocked on the ceiling flows outside by natural ventilation using the dominant South-West refreshing wind. The two volumes - the room and the roof - are separated by a wood mesh.
From a constructive point of view, the classroom unit is composed of:
- a concrete slab acting as soil and foundation
- a brick basement (50 cm) to protect the mud walls against humidity
- the earth walls: rammed earth on North & South, perforated CEB on East & West
- a wooden frame supporting the roof
The classroom units are separated by small gardens which aim to be natural breathings in the school, bringing freshness and natural comfort to the children and improving the cooling system.

ENTRY #493272659INSIDE OUTDesign Team: Francesca Vittorini, Andrea Tabocchini (Italian student)
How to design an exciting classroom typology that is functional, scalable and perfectly blended with the environment?
“Inside Out” takes inspiration from the many patterns that are present in the site and in the local culture (the textures of the typical kente clothes, the rigid grid of the oil palms, the layout of the vegetable gardens...) to propose a flexible scheme that transforms the boring standard classrooms layout into a more engaging sequence of multifunctional spaces with different levels of openness.
By staggering the walls and aligning them with the existing grid of the palms, the boundary between inside and outside is eliminated, and the trunks of the palms become the continuation of the walls, domesticating the landscape. Furthermore, the transversal rotating panels can be completely opened, extending the classroom outside with a porch, or a longer wall usable for outdoor classes, or a rows of hammocks, or a vegetable garden, or...
MATERIALS, CONSTRUCTION & BUDGET:
To make the local population active in the construction phase - and to propose a sustainable and easily replicable design - the project is based on a creative use of abundant local materials and a thoughtful use of local labor and traditions.
The 60cm wide walls are built with big blocks of local rammed earth with different colors (0$), recalling the textures of the kente clothes, protected and built on top of concrete curbs (350$) that prevents from prevents rising damp; the floor (300$) is a mixture of clay and concrete; the structure of the corrugated aluminum roof (300$) consists of wood elements with a 10x10cm section (1700$), while the rotating panels that ensure a very bright and ventilated environment are made with thin wood strips (500$).
The result is a building that respects and valorizes the site, the people and their culture, buildable by local labour (500$) with a budget lower than 3 700$.

DESIGN TEAM: Shriya Magotr (student), Bhagyalakshmi Umapathy (student) and Veedesh Deby(student), (India) DESIGN BRIEF
Our main objective was to produce an environmentally and socially-responsible design.
After an extensive material research in relation with the context, it was decided to use rammed earth and compressed earth blocks (CEB) as the main materials for the construction of the building. The walls of the building obtain their richly coloured walls due to the rammed earth. A thick layer of thatch has been used for the roofing. This type of roof is ideal for the hot climate of Ghana. Being a naturally waterproof material, it prevents moisture from entering the interior space. Corrugated metal sheet is used below the thatch, to prevent the metal sheet from overheating. The truss which is supporting the roof structure is made of bamboo.
High ceilings allow cross ventilation, via a pattern of square perforations between the rammed earth blocks. Climatic considerations inspired the volume and facade: a high interior with continuous cross-ventilation helping to guide the humid and hot air away. Hence, the facade is perforated according to the rhythm of the compressed earth blocks (CEB) masonry, giving the classroom its luminous sight. The challenge of limited resources for this project became an opportunity. Not wanting to take any risk in this project for structural issues, we used concrete for the plinth so that the structure has stability, durability, and remains free from seepage. Rotatable bamboo screens have also been used so that the amount of light entering the building can be adjusted according to needs.
Approximate Cost of construction:
Foundation and mud plastering: $ 2000
Rammed Earth walls: $ 450
Roofing (Corrugated metal sheet and thatch): $ 1600
Roof structure (Bamboo truss): $ 1500
Compressed Earth blocks: $ 100
Fittings (Nails and bolts): $ 500
Total Budget: $ 6150

Education takes Flight
Design Team: Caleb Ferro (Architect) and Naomy Parikh (Student), India
Schools are essential to a country’s future and the steps taken towards education determine a country’s progress.
Architecture plays an important role in facilitating as well as enriching the experience of learning within a school in turn improving the education. The school at Abetenim would be an important cog in the growth of education within Ghana.
A traditional rectangular classroom would be the first thought that comes to mind when it comes to creating a low budget school for a developing nation. But limiting it to that sort of set up would only mean that the users within would have a restricted learning experience which would possibly not benefit much. So, as a design team we decided to take this traditional set up a few steps further and not by bringing a whole new definition to it, but by making a few tweaks to enrich the experience of a classroom.
The classroom module which measures as 9m x 6.5m has been designed to allow for multiple usage patterns which allow students to use a classroom in various ways other than just sitting at their desks; this freedom of usage patterns is quite essential to the growth and education of individuals. The openings and storage spaces allow for students to customize their classrooms. One side of the classroom connects to the courtyard while the other opens on to a platform which looks out to nature. The volume of the classroom as well as the openings has been carefully designed to ensure comfortable environmental conditions inside.

Design Tean: Kate Ryle (Australia)DESIGN RESPONSE
This proposal aims to fuse traditional building methods with a modern design vocabulary thus creating a new architectural language. The challenge of the limited resources posed as an opportunity. Mud or earth as a building material often has the stigma attached of being a poor man's material. The truth of the matter is, earth is actually an exceptional building material that can be used in a very refined way. Rammed earth is non-combustible with high thermal properties to maintain a consistently comfortable internal temperature. The mud bricks are non-toxic and acoustically sound. The construction methods of these locally sourced materials utilise local knowledge. The design is intended to contribute to the body of works aiming to promote the cultural acceptance of rammed earth and mud bricks as an architectural material. COST BREAKDOWN ($USD)

LABORATORY UNIT IN ABETENIM COMMUNITY SECONDARY SCHOOL
Design Team: Francesco Frassinelli and Sara Lauro, architects (Italia)
The laboratory unit for the secondary school in Abeteneim is the element we focused on. We carefully considered both the typical climate of Southern Ghana, the local building materials and the students’ needs, in order to realize a sustainable and resilient architectural unit, which would also express a deep sense of belonging. The architectural components, i.e. form, structure, light, aesthetics…are mainly inspired by local natural elements, like earth, sun, rain and wind.
The design is geometrically very simple, so as to allow a simple construction process: every single part is well defined in its organic function and its expressive power.
The project is made up of three parts: the laboratory, an inner place for school activities, the outdoor shaded area, a connection place sheltered from the sun and the rain, and the leisure area, a shaded and airy place where students can meet each other and spend their free time.
An asymmetrical butterfly roof covers the entire space, the indoor and the outdoor one. The laboratory plan is like double and opposite “C”, differently oriented to allow the prevailing wind from West-SouthWest to get in through doors on opposite walls, providing fresh air in the indoor space.
A distance is left between the roof and the top of the walls : a bamboo mat is used here as a secondary ceiling for the inner space, thus ensuring good air circulation to refresh the warm air from above. Natural cooling and warm air evacuation are also provided by the evaporation coming from the nearby productive gardens plants (indicated in the masterplan), as much as by the action of the filtering bamboo mat. Bamboo is also used vertically to create shelves to store lab equipment, like microscopes, burners, books and so on.
The big roof overhanging provides shade and creates additional outdoor area for social life, together with the outer partition walls, with east and west fronts exposed to sunlight most of the day. The outdoor partition walls have some openings in them: their thickness and shape vary according to the free time activities they can be used for: taking a nap, reading, chatting...The orientation of some walls allow the prevailing wind to pass through.
The base of the building is made of tamped loose earth plus a thick layer of “blinding”; the wall foundations are made of stones stacked with light concrete, and the roof structure foundations are small concrete footings. An “earthen floor” connects them. The walls, with a thickness of 14" and 20", are made of sun-dried bricks (adobe), laid with mud-sand or weak cement-sand mortar (if necessary). They are capped with a wooden beam or a concrete bond beam and mud plaster is applied outside to protect the wall. The light and elastic roof structure is made of local iron wood timber with a dimension 2”x10”and distanced from the heavy and rigid adobe walls. Both structures can be built at the same time, to optimize working time and to leave them structurally independent. The butterfly roof, made of corrugated zinc sheets, is supported by wooden purlins. A big metal gutter runs between the sloping roofs, to channel the rainwater and store it in tanks. The bamboo mat, acting as a secondary layer beneath the zinc sheets roof is hung from its structure. The shelves are made of bamboo and wooden boxes. The door panels, made of bamboo aligned side by side into a wooden frame, provide air flow even when closed. The openings in walls are created using local handcrafted clay jars with no bottom, sealed in the earthen walls, used as disposable formworks.
