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, DPC, we established ourselves as a separate firm in 2015, dedicated to the preservation of historic and contemporary buildings.
