BAST have taken a proactive attitude to research in order to experiment with the diverse potentialities of each project. At each step of the design phase, they propose multiple different solutions. As a result, they do not follow a set formal method; instead, their projects go through an evolutionary process. BAST's architecture practice is located in Toulouse, France. The architects recall ideas of modern assemblage and montage: the structural unit is challenged by the superposition of logics, façade layers, colliding structures, sections. The overall logic derives from resemblances, things that look like something else, but are not exactly what we expect. These elements are mixed together.
