Skyline Massings Show Future Growth in Market East and Washington Square West, Center City

In Philadelphia, new development continues to constantly change the cityscape. Buildings with dominant height and/or great mass are being built on a regular basis, drawing the public’s attention. The neighborhoods that are seeing the most change are Center City (particularly Center City West) and University City, and now Market East has recently joined that list with its rising number of new high-rises proposed and under construction. Both office towers and residential buildings are in the works in the area, which are all expected to be built within the next several years. Today YIMBY presents massing renderings that show the developments’ impact on the future skyline.

Looking Back at the Construction of Two Commerce Square at 2001 Market Street in Center City

In 1987, construction was finished at One Commerce Square in Center City, with the building opening in October, but the complex was still unfinished as a second tower was planned. Two Commerce Square would rise at 2001 Market Street to the west of the first building, filling in a gap between the finished structure and the Independence Blue Cross Tower. The second tower rises 565 feet and 41 stories tall. Designed by I. M. Pei and Partners and developed by Maguire Thomas Partners of Los Angeles, the Commerce Square complex was completed in 1992 and this became last structure built in the 1980s boom after the unofficial Gentleman’s Agreement height limit was eliminated.
