Sumit Singhal loves modern architecture. He comes from a family of builders who have built more than 20 projects in the last ten years near Delhi in India. He has recently started writing about the architectural projects that catch his imagination. Library for the community in Muyinga, Burundi by BC ArchitectsFebruary 13th, 2014 by Sumit Singhal
Article source: BC Architects The first library of Muyinga, part of a future inclusive school for deaf children, in locally sourced compressed earth blocks, built with a participatory approach. Our 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 en 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.

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.

This “hallway porch” is a space often encountered within the Burundian traditional housing as it provides a shelter from heavy rains and harsh sun. Life happens mostly in this hallway porch; encounters, resting, conversation, waiting – it is a truly social space, constitutive for community relations.

Transparent doors between the columns create the interaction between inside space and porch. Fully opened, these doors make the library open up towards the adjacent square with breathtaking views over Burundi’s “milles collines” (1000 hills).

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.

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.  Image Courtesy © BC Architects The general form of the library is the result of a structural logic, derived on one hand from the material choice (Compressed Earth Blocks masonry and baked clay roof tiles). The locally produced roof tiles were considerably more heavy than imported currogated iron sheets. This inspired the structural system of closely spaced columns at 1m30 intervals, which also act as buttresses for the high walls of the library. This rhytmic repetition of columns is a recognizable feature of the building, on the outside as well as on the inside.

Climatic considerations inspired the volume and facade: a high interior with continuous cross-ventilation helps to guide the humid and hot air away. Hence, the façade is perforated according to the rhythm of the Compressed Earth Blocks (CEB) masonry, giving the library its luminous sight in the evening.  Image Courtesy © BC Architects The double room height at the street side gave the possibility to create a special space for the smallest of the library readers. This children’s space consist of a wooden sitting corner on the ground floor, which might facilitate cosy class readings. It is topped by an enormous hammock of sisal rope as a mezzanine, in which the children can dream away with the books that they are reading. The future school will continue to swing intelligently through the landscape of the site, creating playgrounds and courtyards to accomodate existing slopes and trees. In the meanwhile, the library will work as an autonomous building with a finished design.
