HHL Architects worked on the design of an urban park incorporating the expanded site setting for St. Paul’s Cathedral by combining Erie Street with the cathedral block into a unified, landscaped, public space.

St. Paul’s Cathedral also owned a former bank branch at 4 Cathedral Park, where HHL Architects was engaged to adaptively reuse the building into the offices for the church on the first floor, and to provide community space for events on the upper floors. The building is now called the Flickinger Ministry Center.
