Last but not least: “Split Switchback Stair Housing” on a 50’ x 100’ site, aligning with the neighboring buildings at the street side, and forming a party wall with one neighbor to create a fire lane on site. From our Portland entry for the 2025 National Single Stair Design Competition.⁠

BUILDING RESEARCH:
CENTERING BUILDINGS IN THE CONSTRUCTION OF KNOWLEDGE

The Preston H. Thomas Memorial Symposium, "Building Research" on April 17th seeks to reignite the curiosity buildings inspire by asking: How can we center buildings and the knowledge that emerges from their construction within broader conversations about research in academia? How do we narrow the gap between academia and practice? How do we enable research to inform architectural practice?

Through rigorous single-building case-study lectures, participants will investigate the complex material and economic trade-offs among affordability, building performance, and carbon reduction as forms of applied research.

An accompanying exhibition titled CURIOUS CONSTRUCTIONS: SPECULATIVE MATERIAL ASSEMBLIES will be on display starting on April 16th in The Nave on the 3rd Floor of East Sibley Hall. The exhibition is a research and design initiative that explores unconventional, low-carbon material assemblies, challenging traditional construction practices through Building Research.

Adapting “Split Switchback Housing” to three new sites with different characteristics helped us stress test the idea and flesh out our vision for single stair multifamily housing in the US. Housing thats more sustainable, communal, and economical.
