Recognizing that some healthcare treatment may not require a hospital stay but may require an extended stay in town, the Seattle Cancer Care Alliance (SCCA) House is designed to house patients visiting general oncology clinics and long-term follow-up programs at the Seattle Cancer Care Alliance. Designed by Weinstein A/U Architects and built by Walsh Construction, the SCCA House operates similar to a Ronald McDonald House, offering several communal areas and shared kitchen and dining facilities combined with private suites. Other common areas include a living room, meditation room, resources center, wellness room, laundry room, and rooftop garden. The 80 residential suites are distributed across four upper floors. Shuttle service is provided between the house and SCCA clinics as well as to local grocery stores.

Many patients experience financial hardships because their expenses at home don't go away while they're in treatment,” says Debbie Fraley, housing and family assistance coordinator for SCCA. "We hear every day that second only to the outcome of a patient's treatment, worrying about local housing and affording that housing is the biggest stressor for patients and their loved ones."

The SCCA House, which meets LEED Silver requirements, is designed with a number of green attributes including a fully accessible green roof on various levels of the house as well as a multi-level rooftop irrigation system, courtyard planting and storm-water detention planters in lieu of on-site detention tanks. The green roof is designed to help reduce heat island effect, as is the facility's underground parking. The parking facilities also include special spots for fuel efficient vehicles. Combining a highly efficient HVAC system with rooftop heat  recovery units, extensive daylighting, energy-efficient indoor lighting, and other energy-efficient components, the building is designed to meet Architecture 2030 Challenge targets.

In addition, outdoor light fixtures are designed for light pollution reduction. Windows are double pane to retain heat and have a special glazing to reduce sound and heat transference. Low VOC adhesives, paints, sealants, carpets and composite wood items as well as rapidly renewable materials were sourced for the interiors, such as bamboo. High-efficiency plumbing fixtures should reduce water use by 30 percent from standard usage. Polished concrete floors and intensive filtration systems throughout most of the common areas keep areas easy to clean and prevent dust collection.
