Looking Back at the Construction of One Commerce Square at 2005 Market Street in Center City

By Thomas Koloski

In 1984, the unwritten Gentleman’s Agreement that forbade building above the 548-foot-high statue of William Penn atop City Hall was about to be eliminated when, in April, developer Willard Rouse proposed a skyscraper development that eventually became Liberty Place. The proposal apparently influenced more developers and architects to build towers above the former height limit. The Commerce Square twin towers were revealed at 2005 Market Street in Center City at the end of the year. Designed by I.M. Pei and Partners and developed by IBM and Maguire/Thomas Partners, the 41-story towers were not built simultaneously, as One Commerce Square was the first building finished in the complex.

The steel structure of the office building under construction at 2222 Market Street, in Center City West, is nearly topped out.

Observing the Construction of Two Liberty Place

By Thomas Koloski

Among the multiple structures that make up the Liberty Place complex, Two Liberty Place is the second tallest, rising 848 feet and 58 stories, yet it is the largest by area, with 1.2 million square feet. As such, the building is one of the most largest skyscrapers in Philadelphia, as the Comcast Center measures nearly 1.4 million square feet and the Comcast Technology Center holds 1.5 million square feet. Two Liberty Place is located near the heart of Center City at 50 South 16th Street. Just like the rest of Liberty Place, the tower was designed by Helmut Jahn of Murphy/Jahn, who had unfortunately passed away in a bicycle crash in Chicago in May. The project was developed by Willard Rouse of Rouse and Associates, which eventually became Liberty Property Trust.
