Roof Restoration
Washington, DC
Built in 1867, this National
Historic Landmark has undergone a $5 million rehabilitation to restore its
distinctive 75,000-square-foot copper roof and reconstruct three porticos. The
copper roof had deteriorated over time, and Hoffmann Architects was asked to
investigate the issues and design remedial solutions to meet stringent historic
preservation requirements. The Greek Revival building was formerly home to the
U.S. Patent Office and now houses the National Portrait Gallery, Archives of
American Art and National Museum of American Art |
