Traugott Terrace provides fifty units of "clean and sober" housing for individuals with very low incomes in the Belltown neighborhood of downtown Seattle. The housing was developed to broaden the services of the Matt Talbott Center, a multi-service facility that offers Seattle's homeless population a core of programs built around initiatives to stop substance abuse and prevent relapse. Twelve transitional, single-room occupancy units on the second floor, along with a common kitchen, dining, and lounge area, serve participants in the Matt Talbot Center recovery program. Floors three through six contain 38 studio and one-bedroom apartments.
The new housing was constructed above the existing Matt Talbott Center and within its adjacent parking lot. The housing was designed to surround a common outdoor deck built on the roof of the Center. The form minimized construction above the existing structure and provides continued access to natural light and ventilation despite its mid-block location. The project was designed to the standards of Seattle City Light's Built Smart(sm) program, which provides incentives for envelope, HVAC system, and lighting upgrades that reduce energy consumption, and to achieve green building certification through the U.S. Green Building Council's LEED(r) Rating System.
Energy saving strategies included the creation of a high-performance building envelope (using good insulation, windows with a low U-value, and tight construction techniques), energy-efficient lighting, ample daylighting, a heat-recovery ventilator for replacement air in all common areas, reduced hot water use, and a high-efficiency, gearless traction elevator. Low-flow fixtures that go beyond Energy Act requirements and front-loading washing machines reduce water use by a third. Materials were chosen for their recycled content, local production, and low toxicity, and sustainably harvested lumber was used for all framing. During construction, an indoor air quality plan was followed, and more than three-fourths of construction debris was recycled.
