We built the school using the SuperAdobe technique as we did for the walls of the the first school. The construction technique developed by Iranian architect Nader Khalili in the 70’s proved itself to be fast and low cost.

We filled the bags with a damp stabilized mix and tapped it to create compacted giant bricks, which we layered and stacked on top of each other to form the foundation as well as the walls. We designed buttress walls to strengthen our structure every 3m and use them as benches inside the courtyard. They also shade the walls from the sun and contribute to keep a fresh atmosphere inside the classrooms, adding to the natural thermal qualities of our earth building. The roof’s primary structure is supported on the buttress walls. A gap was left between walls and roof to allow for natural ventilation and additional light inside. We left the bag wall shaped apparent to inspire the village to build their house using this technique.

During the construction of this school, we built arches made of supeAdobe as an architectural challenge to be further explored in the construction of following schools. First, we casted a 10cm concrete base and then layed the superAdobe over. The air inside this classroom was much more fresh than the others.
