Daniel Kaven + Trevor William Lewis

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 high-rise buildings, mixed-use buildings, and environments for corporate clients such as Nike, Converse, Microsoft, and NAU. 


Although formally educated in architecture, Daniel Kaven’s career in design has additionally relied on his aptitude as a filmmaker, photographer, and painter. Daniel has directed, produced and screened films in conjunction with his mixed media work to much acclaim. In architecture, Daniel draws upon his talents as a visual artist, blending graphics and two-dimensional design with bold-sculptural forms and concepts. 

In 2015, Daniel formed Kaven + Co. to facilitate visionary in-house projects.  Since its inception, Kaven + Co. has originated well over $100 Million in development. Most notably under development, in partnership with Guardian Real Estate Services, is Block 33, a 400,000sf mixed-use tower in downtown Portland, Oregon, which features a public market, office, hotel and apartments.


Trevor William Lewis builds upon years of experience within internationally recognized architecture firms, where his most recent focus has been energy efficient high-rise and cultural buildings. Trevor endeavors for modern, conceptually-driven design solutions, and is always looking beyond traditional practices to sensibly manage energy and resources, within the paradigm of high design. He welcomes any design challenge, and is always considering detail, material, and craft at the finest scale; while responding to culture and context at the broadest range.  

Notable projects in conjunction with other firms include the newly completed Bend Cancer Center (2014 IIDA Jurors Choice Award, 2014 IIDA Healthcare Award); the 22-story 12W mixed-use building in downtown Portland (2010 AIA Built Merit Award); a Community Center and Library for the the Chinese Municipality of Xiamen, as well as the future expansion of the Portland Art Museum.  Over the past 10 years, Trevor has associated with the design of projects for many leading companies and institutions including Microsoft, Nike, Converse, NAU, Caterpillar, the Judicial Branch of California, St. Charles Health System, University of North Carolina, and the University of Oregon.

Trevor is a LEED Accredited Professional, and is a Registered Architect in Oregon, Washington, Michigan, Texas and New York, and is certified by the National Council of Architectural Registration Boards. 


Mike Perso has spent the last 10 years collaborating on diverse project types, ranging from mixed-use high rise to healthcare and research facilities to public space.  His breadth of project experience from conceptual design and programming to the design and technical development of complex exterior enclosures is paired with a depth of knowledge of how buildings are put together.  He values strong communication between all members of the client and design team and brings a sensitivity toward the experiential quality of space and a focus on crafting high-performing buildings to every project he works on. 

Mike has been involved in the design and technical development of projects for a diverse and notable group of clients throughout his career including the City of Portland, Oregon State University, the Max Planck Society, Bay Area Hospital, the University of Pittsburgh Medical Center, Kaiser Permanente, Fresno State, Peet’s Coffee & Tea and the United States Department of State.
