Heller & Metzger in Washington, DC

Department of the Interior Modernization

Washington, DC / Shalom Baranes Associates

The 1.2 million sf Main Interior Building occupies two full city blocks in the heart of downtown Washington, DC. Constructed in 1936, it is a significant example of the federal WPA Moderne style and listed on the National Register of Historic Places. The building is being completely modernized to GSA standards, including restoration of its historic features and significant interior spaces. Special protection and conservation systems were designed for the many important WPA-era murals throughout the building. As part of the renovation of the Cafeteria space and the Childcare Center, Heller & Metzger served as both the specifiers and as the sustainable design advisors. By incorporating such elements as skylights to increase daylighting and a food composting system in the kitchen facility, the Cafeteria Renovation was able to achieve a Platinum LEED rating.
