Design Team: Tina Wunnenberg (Wismar, Germany)
The design is based on the pattern commonly found in Ghana and the Ashanti Region Compound Houses. These houses are rectangular, one or two storeys high and situated in the middle of a large courtyard. Usually several families live in the same compound. This pattern can be found both in cities and in small villages. My goal is to transfer this compound pattern to smaller single-family homes and so to combine traditional and new structures. For better ventilation, the structure is fragmented and individual pieces were removed. Following the current settlement character, the roads should have a slope of 1.50° so rainwater drains away quickly from the settlement during the rainy season . In addition, the plot should protrude above the road - at the lowest point by 10cm and by 58cm at the highest. Thus, the beginning and the end of the property will be clearly marked.
There are four small houses and two pavilions – the plumbing pavilion and the kitchen pavilion. The design makes use of two earth-building techniques with self-made clay bricks to offer new building techniques to the locals. The main walls of the pavilions consist of rammed earth and also add to the optical variety. For a good ventilation and drainage it is useful to situate the wet area in a detached building because the walls are made of clay. Life in Ghana largely takes place outdoors. The courtyard is used for cooking, washing, playing and general life. That is the reason for the kitchen pavilion. It offers the possibility to use the outside area during the rainy season. The kitchen located in the house offers a storage area for food and cooking utensils, where they are protected from theft by animals and humans. The houses are about 225 square feet and can be divided by a wall into two rooms when the family grows. For this option, you can choose to add a second door to the same building or to incorporate a large lintel at the beginning of the building process to make it easier to add a second door later. It is possible to add beds between the houses.
The foundation consists of stacked stones or mudstones with a circumferential termite protection plate, which prevents vermin infestations. The doors have a double swing. The outside door offers protection and is made of solid wood. The inside door consists of a wooden frame and a mosquito net to protect against mosquitoes. So you have the possibility to open the outside door for ventilation and the inner door protects against mosquitoes without impairing ventilation. The windows consist of a wooden frame with a mosquito net and a lamellar wood window with adjustable blades. The size of the wood sheets is selected so that when they are completely opened enough sunlight comes into the interior. The option remains to use a standard system of glass lamellae if more light is desired. The advantages of wooden slats include the durability, the ecological aspect and better protection against burglary.
The roof is a pent roof made out of timber and aluminum corrugated iron. The large roof overhang protects the walls from rain and sun.
The design should be available in a book with comprehensive building instructions, which families can purchase in order to build their own house together with friends and relatives using materials from the environment. There is also the possibility to employ workers and to buy materials such as bricks, if saving money is not a concern and the families prefer not to build the house themselves. Therefore, standard measurements were taken into account.
