William / Kaven Architecture is a multidisciplinary design studio based in Portland, Oregon, working in architecture and interiors. The studio was officially formed by brothers Daniel Kaven and Trevor William Lewis in 2004, continuing a lifetime of collaboration that began as children in their home state of New Mexico. Collectively, the brothers have amassed a significant portfolio in their design careers that includes award-winning residences, energy-efficient buildings, mixed-use projects, and environments for corporate clients.

William / Kaven Architecture is committed to developing and delivering innovative, inspiring and energy-efficient projects that constantly push the envelope. We take an exploratory and creativity-driven approach to every phase of design, prioritizing not only an aesthetically excellent end result, but also an informed, open and responsive process.
