The Best Affordable Housing Architects in Seattle, Washington

11 Min Read

With an estimated 11,751 people living on the streets or in shelters in 2020, homelessness continues to be a major problem in one of America’s fastest-growing major cities. Government and nonprofit organizations alike have been working to find long-term solutions for this crisis. One proposed solution: create more permanent supportive housing options.

This list presents some of the best affordable housing architects in Seattle, Washington, architects who have risen to the challenge of addressing this deep social problem. On this list, you will find many Leadership in Energy and Environmental Design Accredited Professional (LEED AP) and LEED for Building Design and Construction (LEED BD+C) certified members. You will also find fellows of the American Institute of Architects (AIA/FAIA) and the National Council of Architectural Registration Boards (NCARB). You’ll also find those who have lent their services to structures that have been recognized by the National Association for Industrial and Office Parks (NAIOP) for their contribution to helping this cause.

The winner of the 2019 Gold Nugget Merit Award for Best Affordable Housing Community 60 dwelling units/acre or more and the 2018 NAIOP Night of the Stars Affordable Housing Development of the Year is Arbora Court. University Christian Church and Bellwether Housing teamed up to develop the 138,949-square-foot structure with families in mind. Weber Thompson Architects designed 40% of the units to have two or three bedrooms to accommodate formerly homeless families.

SAGE Architectural Alliance designed the Arcadia House Homeless Youth Center in Auburn to serve young people in need, from birth to age 24. Developed by the YMCA and operated by Nexus Youth and Families, it houses a day shelter that converts to a 12-bed overnight emergency shelter. Five three-bedroom apartments give occupants their own bed and bath, sharing a common kitchen and living space with two other youth. Mental health counseling, drug and alcohol treatment, and licensed childcare are also available on-site. Administration offices are also situated on the property. Committed and caring staff help set at-risk youth on a path to self-sufficiency. The project was designed to meet the ESDS, with 50% native plants incorporated into the landscape and low-flow irrigation. It also makes use of water-conserving plumbing fixtures, ENERGY STAR appliances, and LED lights.

The firm’s second project as both architect and developer was The Roost on Hiawatha Place S. This efficient design offers the local arts community rents that are significantly lower than other new developments. With many units designed in a loft-style, the 14,477-square-foot structure provides a lot of extra work or living space. Common kitchen and dining spaces, a TV lounge, and a laundry area also foster a sense of community among its residents. It also houses the nonprofit arts organization Amplifier in its commercial space. The project has a 5-star Built Green certification, at just about a third of the conventional apartment energy usage. A rooftop solar array also provides 85-90% of the property’s domestic hot water.

EW designed the 101,000-square-foot Patricia K. and Jackson Heights  buildings, completed in 2020, for the Community House Mental Health Agency. The buildings bring much-needed affordable housing and retail to 23rd and Jackson at the heart of Seattle’s Central District. Patricia K. includes 53 permanent supportive housing units for individuals with chronic mental illness who are exiting homelessness; offices for administration, case management, and supportive services; and a day center providing meals and supportive services to non-residents. The adjacent Jackson Heights adds 74 units of affordable workforce housing — in studio, one- and two-bedroom layouts — and ground-floor retail to the neighborhood. Half the units are reserved for people with longstanding ties to the Central District, in response to the displacement caused by decades of gentrification. Jackson Heights showcases murals and stainless steel art installations by local artist Kemba Opio that celebrate the neighborhood’s Black heritage, and hopes for its future.

Project by Encore Architects

Located in the “in-between” neighborhood of the Interbay, the Axle establishes itself as the new center of the surrounding neighborhood “spokes.” Encore Architects designed the 150,000-square-foot, 226-unit structure in a “Z”-shape to blend well with the lower skyline around it. This created two triangular courtyards and more façades to see views of the nearby waters through. The LEED Gold project features muted tones that frame the art wall along 15th Avenue West. That combination breathes life into the busy traffic. It was nominated for Multi-Family Residential Urban Development of the Year: more than 100 Units at the 2019 NAIOP Night of the Stars. Zella, another affordable housing project by Encore, was also nominated for this category.
