How We Build
We design thick walls made up with the available earth material (soil, sand, clay, etc...), which benefits from performing thermal qualities and keep the classrooms fresh. We design window openings large enough to let the air in and refresh the classrooms. We build the roof at an elevation from the walls, leaving a significant gap for natural ventilation, as well as natural light. Ultimately, we use local materials to build a best suited building to the climate.
These simple design techniques help overcoming the overheating issue in the existing schools, built with blockwork walls, small windows and a zinc roof. These materials and design create a very difficult work environment for students and teachers alike, affecting their ability to perform and succeed.
Our goal is to spread a technique of construction fast and easy to learn which will create a great atmosphere to study. We team up with both local people and specialists to conceptualize sustainable and ingenious methods.
CONSTRUCTION: December 2016
We tested both the sand-bag and tyre construction techniques on site in Senegal to determine which materials are best suited for local communities. Trials proved that the best approach is to build the classrooms using tyres for the foundations and sand-bags for the walls. A protective outer layer made up of a sand and 8% cement mixture was applied to the sand-bag walls.
