ENTRY # 492608304
LAYEARTH: 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
Foundation/Slab - 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.
$1,850
16 cubic meters of concrete
rebar + mesh
formwork
Walls - Local rammed earth construction methods with formwork are used for the walls. Wood frames are cast into the rammed earth walls to support the windows and door.
$1,200
rammed earth
bricks for jali wall
Windows
$320
(6) standard windows
roof vent louvers
bug nets
Columns/Roof Structure - Roof trusses are spaced 2 meters apart, will be built on site, and fastened to the concrete bond beam. Columns and trusses are to be wood.
$1,050
700 linear feet of 2x4
350 linear feet of 2x2
Roof/Bamboo Screen - Corrugated roof should be light in color if possible. Bamboo screen to be sourced locally.
$2,100
1,400 s.f.. corrugated zinc
bamboo/bamboo support
TOTAL: $6,520
