Lobby Renovations Underway at BNY Mellon Center at 1735 Market Street in Center City

7:30 am on April 21, 2022 By Thomas Koloski

At the time when the Liberty Place project was proposed in Center City, other developers scrambled to join Philadelphia’s skyline race to top the Statue of William Penn atop City Hall. At 1735 Market Street, the skyscraper formerly dubbed Mellon Bank Center, now known as BNY Mellon Center, has long been a major fixture of the Philadelphia skyline. The project, which started to rise in 1987, rises to a height of 824 feet, with a 792-foot-high roof, and 54 stories. The tower was designed by Kohn Pedersen Fox and developed by CommonWealth REIT. Silverstein Properties, the owners of the World Trade Center in New York City, purchased the property in 2019 for $451.6 million; renovations were later announced for the tower.

YIMBY Looks Back at the Renovation of Philadelphia City Hall in the 1980s

8:00 am on April 19, 2022 By Thomas Koloski

Philadelphia’s City Hall has loomed proudly in Center City since it topped out in 1894, but its tower continues to stand only thanks to several renovations. While the municipal floors of the building only rise nine stories high, the clock tower remains the largest freestanding masonry structure in the world to this day. The edifice is topped by a 37-foot-tall statue of William Penn, the founder of Pennsylvania, which brings the tower to a full height of 548 feet. The structure was designed by John McArthur Jr. and Thomas Ustick Walter, and was completed in 1901. In this feature, Philadelphia YIMBY takes a look back at the direly-needed renovation for the top of the clock tower that took place in the 1980s.

Observing The Construction Of Mellon Bank Center and Two Liberty Place

8:00 am on April 11, 2022 By Thomas Koloski

In 1984, plans were approved for the first office tower to rise above the unwritten Gentleman’s Agreement height above the statue of William Penn. One Liberty Place broke ground in 1985 and was under construction until the end of 1987, starting a new construction boom for the city that revitalized the city’s skyline. One Commerce Square had topped out the summer before One Liberty Place rose, but, shortly after the completion of One Liberty Place, the structure of the Independence Blue Cross Tower joined the skyline. By the end of 1988, the Bell Atlantic Tower was also rising, eventually bulking up the skyline by 1989.
