This project is the first library of Muyinga, Burundi, part of a future inclusive school for deaf children, using locally sourced compressed earth blocks, built with a participatory approach. B C Architect’s work in Africa started within the framework of OpenStructures.net. BC was asked to scale the “Open structures” model to an architectural level. A construction process involving end-users and second-hand economies was conceived. Product life cycles, water resource cycles and energy cycles were connected to this construction process. This OpenStructures architectural model was called Case Study (CS) 1: Katanga, Congo. It was theoretical, and fully research-based. 5 years later, the library of Muyinga in Burundi nears completion. square with breath-taking views over Burundi’s “milles collines” (1000 hills). On the longitudinal end, the hallway porch flows onto the street, where blinders control access. These blinders are an important architectural element of the street facade, showing clearly when the library is open or closed. On the other end, the hallway porch will continue as the main circulation and access space for the future school. A very important element in Burundian (and, generally, African) architecture is the very present demarcation of property lines. It is a tradition that goes back to tribal practices of compounding family settlements. For the library of Muyinga, the compound wall was considered in a co-design process with the community and the local NGO. The wall facilitates the terracing of the slope as a retaining wall in dry stone technique, low on the squares and playground of the school side, high on the street side. Thus, the view towards the valley is uncompromised, while safety from the street side is guaranteed. Vernacular inspirations A thorough study of vernacular architectural practices in Burundi was the basis of the design of the building. Two months of fieldwork in the region and surrounding provinces gave us insight in the local materials, techniques and building typologies. These findings were applied, updated, reinterpreted and framed within the local know-how and traditions of Muyinga. The general form of the library is the result of a structural logic, derived on one hand The library is organized along a longitudinal from the material choice (Compressed covered circulation space.
