The Unbuilt Skyline: a Comprehensive Look at Philadelphia’s Major Canceled Skyscrapers

The Philadelphia skyline has grown enormously over the past few decades, yet there are many formerly planned towers that were once planned yet were never completed. Philly YIMBY recently ran a series of articles that shined a spotlight on a number of unbuilt buildings. The designs came in various unique shapes: some featured curves, some boxy, and others with sharp angled cuts that gave them distinct character. While some were notably more appealing than others, even the most subpar of these designs would have dramatically elevated the city’s already impressive skyline to a new level. Today we present what the skyline would have looked like if all of these developments were built.

Looking Back at the Comcast Center, Philadelphia’s Former Tallest Skyscraper

The Comcast Center at 1701 John F. Kennedy Boulevard is the first of a two-tower complex, which had drastically changed the Center City skyline when it passed the height of One Liberty Place, becoming Philadelphia’s tallest building. The structure was completed in 2008 and stands 974 feet and 58 stories tall, with a concrete core and steel floors. The exterior features high quality, mirror-like glass, a departure from the traditional masonry style that Robert A.M. Stern Architects is known for, as seen in limestone-clad towers such as The Alexander at 1601 Vine Street and 30 Park Place in New York City.

A Look Back at How FMC Tower Elevated the West Philadelphia Skyline

The 736-foot-tall, 49-story FMC Tower at 2929 Walnut Street has stood as one of the tallest towers in Philadelphia since its completion in 2017, with a sharp design that elevates the University City skyline to new heights once seen as barely imaginable for the area. Along with Evo and Cira Green, the tower has given West Philadelphia a dramatic profile with eye-catching good designs. The abovementioned skyscrapers have the same designer, Pelli Clarke Pelli Architects, and all feature angled cuts. Developed by Brandywine Realty Trust, FMC Tower also displays distinctive curvy façades. Nighttime lighting with a red FMC logo topping the north and south faces adds an extra distinctive touch.

Revisiting Visionary Plans for a 30th Street Station District Plan Supertall in University City, West Philadelphia

Several years ago, plans have been revealed for a major megadevelopment to be built on a new deck above the Amtrak railyard on the banks of the Schuylkill River in University City, West Philadelphia. The project is called the Philadelphia 30th Street Station District Plan, as the first phase includes restoration of the historic 30th Street Station. Designed by Skidmore, Owings, and Merrill and developed by Plenary Infrastructure Philadelphia, the master plan shows a large number of high-rises and a supertall skyscraper that would become the tallest, or one of the tallest, buildings in the city.
