Abari Transitional Classroom is a design for a temporary classroom that uses local and salvaged materials in post-disaster environments.
Abari Transitional Classroom was created by Abari in response to the earthquake that affected Nepal in April of 2015. It is provided through a complete open-source guide that aims to promote Owner Driven Reconstruction (ODR), a participatory model that places homeowners at the center of reconstruction through decisions on designs, site selection, and materials. The building techniques are tailored to local environments and resilient to environmental hazards. The project uses local and salvaged materials and considers local knowledge and technology. The components required are bamboo, ropes, GI wire, sand, cement, and aggregate.
