Clark led the construction efforts on the $6.6 million William H. Gross Stamp Gallery Expansion at the National Postal Museum in Washington, D.C. The world’s premier museum gallery dedicated to philately, the new gallery enables the Smithsonian Institution to increase the visibility of its extensive stamp collections and advance its educational mission, reinvigorate public interest in philately.

The National Postal Museum is located  in the old D.C. Post Office Building. Clark Interiors converted the previously occupied  first floor Capitol City Brewery, into a permanent exhibition space. The scope of work included construction of a new mezzanine space, renovation of the first and ground levels, and installation of more than 70 exterior windows with images of actual stamps.

The space hosts the largest philatelic gallery in the world and includes philatelic gems like the Hawaiian missionary stamps, the inverted Jenny airmail error stamp, and other rare pieces  previously stored in the museum’s vaults. Visitors  can enjoy more than 20,000 exhibit pieces, including touch screen interactive displays and artifacts such as a letter mailed aboard the Titanic’s first and only voyage. The gallery’s Stamp Salon includes a 19-foot tall by 55-foot long wall that displays 20 exhibit cases, and a 62-foot arc wall that displays 13 of the most rare and highly-valued stamps.

The 14,000 square-foot project earned LEED for Commercial Interiors certification.
