Designing One Liberty Place, the Tower that Transformed Philadelphia’s Skyline
One Liberty Place at 1650 Market Street is an intricately designed skyscraper has dominated the skyline of Center City for over three decades. Designed by Murphy/Jahn and developed by Rouse and Associates, the tower is clad in a pattern of stone, metal, and glass that rises up to the angled crown and the thin spire. The tower first rose to its final 61-story height in the beginning of 1987, when the top floor was assembled beneath the future spire. Philly YIMBY looks back at the design process by architect Helmut Jahn via drawings from 1984, which show multiple design iterations.
