The slender core of the 377-foot-tall, 19-story CHOP Hub for Clinical Collaboration has topped out at 3501 Civic Center Boulevard in University City, West Philadelphia. The building is a part of a $3.4-billion expansion for the Children’s Hospital of Philadelphia. Designed by Perkins + Will, the tower will connect to the existing hospital structure.
Yesterday Philly YIMBY published a feature story covering the 1,050-foot-tall Philadelphia World Trade Center supertall planned at 456 North Christopher Columbus Boulevard on the Delaware River waterfront in Northern Liberties in 1988. After the proposal fell through, developer Carl Marks Real Estate Group contracted Alesker & Dundon Architects to redesign the project as four shorter yet still impressive skyscrapers, which were to take up most of the 5.5-acre site. The development would now be known as World Trade Square, and later as Renaissance Plaza.
In 1988, plans were revealed for a 1,050-foot-tall, 65-story Philadelphia World Trade Center supertall at 456 North Christopher Columbus Boulevard on the Northern Liberties waterfront. The tower would have stood just to the north of the Benjamin Franklin Bridge, located close to the boundary between North Philadelphia and Center City. The plan, which later evolved to the World Trade Square project, consisted of three shorter high-rises alongside the main tower. The skyscraper was designed by Kling Lindquist, which was also bend the Bell Atlantic Tower and the unbuilt Center City Tower. Carl Marks Real Estate Team, along with Lance Silver and Stuart Harting, were the developers.
Ever since the 500-foot-plus height limit was erased after One Liberty Place went up, developers rushed to construct buildings taller than the prior boundary. Designed by WZMH Architects, the twin towers of the Independence Blue Cross Tower were originally proposed to stand next to each other, rising 625 feet and 45 stories tall at 1901 Market Street and at 1919 Market Street in 1901 Market Street and at Center City West. The group behind the design is the same as the one that designed the CN Tower in Toronto, Canada. The developer of the twin tower project is The Linpro Company, which has only erected one tower that stands out on the skyline.
In a follow-up to the recent design update to the 12 + Sansom project at 123 South 12th Street, Philadelphia YIMBY shares with its readers exclusive, brand new massing models of the 265-fot-tall, 20-story building’s future presence on the skyline. Designed by Studios Architecture (with Bower Lewis Tower Architects as the architect of record) and developed by Greystar Real Estate Partners, the 412-unit residential building will significantly boost the density in the Market East section of Center City. The tower’s shape and exterior have completely changed since the last iteration.
