3411 Ordway Street, N.W.
Agent: Robert Gurney, Architect
3411 Ordway was designed in 1960 by I.M. Pei for William L. Slayton. The house is only one of three residential projects designed by the architect of the East Wing of the National Gallery, the glass entrance to the Louvre and the Kennedy Library and Museum in Boston. The house was added to the National Register for Historic Places in 2008. Noted for its triple barrel concrete roof visible from both the front and the rear, the house was renovated in 2002 by Hugh Newell Jacobsen and again in 2010 by Maurice Walters.
The current proposal includes a below-grade rear addition and a 2-story garage accessory structure. The addition would be accessed from the existing house through a hallway on the east side and from the garage and the rear yard through a breezeway and courtyard. The lower level of the accessory structure would contain a garage, and the upper level additional living space. This structure would rise approximately 26 feet above the rear alley which is itself approximately a full story below the rear yard. The result is a structure 17 feet above the existing rear yard. The materials for the accessory building are white corrugated perforated metal screen over white frame windows.
The ARC had the following comments:
The ARC commends the below-grade addition. However, the ARC has concerns about the accessory building. Due to its placement facing the rear alley and the significant drop in grade from Ordway Street to Porter Street, the ARC is concerned that the structure not become a beacon, creating light pollution over a wide area. The ARC would like to see additional information on the materials and mitigation efforts to address this issue. The ARC was also concerned about the partial obstruction of site views of the vault from the alley.
The motion passed 5-2.
