There exists a long-standing tradition of full-scale construction in the design studio at the Carleton University School of Architecture. The mantra "building as speculation" is explicitly evoked in varying studio and workshop contexts, ubiquitous within the fabric of the curriculum and design culture of the school. The value placed on 1:1 material engagement and construction techniques is qualified by an understanding of drawing (traditional and technological) as a form of critical, theoretical, and practical speculation. "Building speculations" at Carleton, in other words, are not constrained to conventional notions of design/build, but occur freely in the studio as a form of "sketching" or "modeling" that informs a wide range of design activities. Supported by a fully equipped metal and wood shop and photographic, video, and digital facilities, the "build" tradition at Carleton continues to adjust and transform according to the demands of architectural pedagogy.
