525 William Penn Place repositions the classic 1951 Harrison & Abramovitz modernist office building, located in the heart of Downtown Pittsburgh. The interior and exterior renovations are designed to attract new tenants and increase the property’s value. As a part of the Renaissance building initiative to rebuild downtown Pittsburgh, 525 was among the first skyscrapers built. To establish the tower as a premier “Class A” business address, the design team referenced black and white photos from the 1950s to draw from the history of Pittsburgh’s modernist architecture. The design incorporates patterns, textures, materials, and finishes popular during this era to pay homage to this classic American corporate tower. The project includes a complete renovation of the lobby, addition of a new tenant lounge and fitness center, and an introduction of a new monumental glass curtainwall and entry pavilion along the street level. By carefully weaving new and existing elements together, the street level design creates a glass enclosure that “borrows” the classic façade of a neighboring historic building and merges the streetscape into the lobby to create a grand new entrance.
