Visualizing the Under-500-Foot-Tall Early Iterations of Liberty Place on the Skyline

The Liberty Place complex is emblematic of the Philadelphia skyline as they played a key role in Center City‘s skyscraper growth. The towers currently stand 61 and 58 stories tall, with angled sharp crowns pointing toward to the sky, one tower capped with a tall and another with a short spire. The project was commissioned by Willard G. Rouse III of Rouse and Associates, who had originally pictured a $150 million 38-story tower rising to a height that measured somewhere under 500 feet. Just days after New Year’s Day in 1984, the building was first discussed in a publication about how Rouse won the bid for the site how it may become the city’s premier office tower. The architect, Helmut Jahn, was selected in March, and had produced a rapid succession of concepts under 500 feet, which eventually evolving well above that height. Today we share exclusive massing concepts of how the skyline would have looked if the towers were built to their originally planned height.

A Look at Early Iterations of Liberty Place When It Was Planned to Rise Under 500 Feet in Height

The Liberty Place complex in Center City is known for being the first building in Philadelphia to dramatically break the unofficial 548-foot height limit that was set by the statue of William Penn on top of City Hall. Upon completion, One and Two Liberty Place were the tallest skyscrapers on the skyline, standing at a height of 945 and 848 feet, respectively. The towers were designed by Helmut Jahn and developed by Rouse and Associates, which eventually became Liberty Property Trust. In this feature, Philadelphia YIMBY takes a look back at a number of early iterations of the complex when the towers were planned to stand around or under 500 feet in height.

Looking Back at the Former Proposal to Make the Statue of William Penn Atop City Hall Revolve

The 37-foot-tall statue of William Penn atop the City Hall clock tower brings the structure to a full height of 548 feet. As YIMBY discussed in yesterday’s story, the intended south-facing direction of the statue, crafted by sculptor Alexander Milne Calder, was changed at the last minute, and for nearly 127 years the figure has faced northeast. In this feature, Philadelphia YIMBY looks back at the onetime proposal to have the statue revolve around its axis so it could gaze upon the entire city.

Looking Back at the Originally Intended Placement of the Statue of William Penn atop City Hall

The statue of William Penn has stood at the very top of Philadelphia City Hall in Center City for well over a hundred years, facing northeast. The large figure of the Quaker was crafted by sculptor Alexander Milne Calder, who also produced the smaller statues just above the clock house and around the entire building. The 548-foot-tall Philadelphia City Hall was designed by John McArthur Jr. and Thomas Ustick Walter, renown architects of their time. In this feature, Philadelphia YIMBY takes a look back at the original southern direction the statue was supposed to face and at the subsequent change.

Looking Back At Developments Under Construction In 2017

Philadelphia has had certain key years when skyscraper construction saw a notable surge, when many developments were underway at the same time. For instance, much of the current Center City skyline took form in and just after 1987. Another key year for construction took place in 2017, when various high-rise projects spanned multiple neighborhoods. Most of these developments stood under 500 feet, with some barely noticeable from afar, yet others added significant bulk to the skyline. The tallest skyscraper under construction was the Comcast Technology Center, the city’s first supertall tower and still the city’s tallest building. In this publication Philadelphia YIMBY looks back to when this collection of developments was underway four years ago.
