ANHALT RENOVATION + ADDITION Seattle, WA Converted from an apartment building to generic medical office space in the 1960 s, the historic 190 s Anhalt building and site have been restored back to their original residential use, and configured to accommodate 2 apartment units. A new addition has been constructed on the northern third of the property, replacing a surface parking lot. The existing building has been designated a historic landmark with emphasis on preserving the exterior and the distinctive circular stair tower. Consistent with the Secretary of Interior Standards for Rehabilitation, new work has been designed to be compatible with, but also differentiated from, historic building elements. Building on the traditions of Frederick William Anhalt (1895-1996), the addition provides 15 apartment units configured around a new courtyard positioned between the two structures. Largely self-taught, Anhalt developed numerous apartment buildings in Seattle, and considered a landscaped courtyard an integral component to his projects. He preferred grouping apartments around stair towers accessed from courtyards, to the standard organization of internal corridors and long hallways. The new addition also continues existing urban patterns of the neighborhood, further promoting a well-defined street wall, and continuing the rhythm of covered building entry stoops. Parking for 18 vehicles, accessed from the alley, is provided below grade where the two buildings connect. The development is participating in an Energy Code Demonstration Program, in partnership with the City of Seattle, testing an outcome-based approach to energy code compliance designed to encourage the re-use and retrofit of existing buildings through measuring the total energy usage for the site as the sole metric. As a result of the program and energy modeling, the original historic windows could be retained with the addition of a thermal cellular shade on the interior, an energy efficient heat-recovery system was installed in the historic building, and specific areas of the existing building were super-insulated. The new addition has a high-performance thermal envelope and all 9 apartment units incorporate sub-metering and user-friendly controls, allowing the property owners to generate a feedback loop, aimed at encouraging energy conservation by the residents.
