Architectural Preservation Studio, DPC is a women-owned design professional-service corporation founded by a collaboration of architects, preservationists, and material conservators. We are one of the nation’s leaders in historic preservation, with advanced expertise in building conservation technologies, architectural restoration, and exterior envelope repairs. The professional staff of the studio has been involved in some of the most important preservation projects of the last two decades, including Frank Lloyd Wright’s Solomon R. Guggenheim Museum and Fallingwater, the historic Breakers and Château-sur-Mer mansions in Newport, RI and Louis Sullivan’s Bayard-Condict building in NYC. Additional projects include theaters, academic structures, courthouses, museums and other iconic structures.  We are a certified WBE in the City of New York, the State of New York, The Port Authority of NY & NJ, and with the WBENC.

Our evolution: Founded in 1889 in St. Paul, MN, the architectural firm, Reed & Stem, moved to NYC in 1903 upon winning the competition to design Grand Central Terminal. Later known as Fellheimer & Wagner, then as Wank Adams Slavin Associates (WASA), the preservation group was founded in 1979 as a department of the WASA architecture and engineering firm. Now known as Architectural Preservation Studio, PC, we established ourselves as a separate firm in 2015, dedicated to the preservation of historic and contemporary buildings.
