BAST

M45 is located on a narrow, elongated plot sloping down toward a stream within a forested landscape. The building is positioned parallel to the site’s contour lines, allowing the terrain to be altered as little as possible and minimizing excavation. 


The volume follows the natural profile of the land. A mono-pitched roof accompanies the slope of the terrain, with its ridge oriented toward the access path. An extended roof overhang creates a sheltered outdoor zone, offering protection from rain and summer sun.



The building rests on a base of polished concrete and concrete block masonry, which also forms the ground floor surfaces. The primary structure is constructed from solid Douglas fir timber. Two load-bearing rows of posts and beams—located at the ridge and along the wall plate—support the rafters. Their depth allows for the integration of wood fiber insulation within the roof structure.


Glazed openings are fitted with sliding frames in natural aluminum. The roof is finished with traditional canal tiles. Solid façade areas are insulated with wood fiber and clad in overlapping Douglas fir boards.


BAST (Bureau Architectures Sans Titre) is based in Toulouse, France. The studio’s work is grounded in a philosophy of revealing the existing elements of each project and questioning its context and meaning, often resulting in simple and essential architectural engagements.
