Comcast Center










Comcast Center is a skyscraper in Center City, Philadelphia. The building officially opened for business on June 8, 2008, and its primary tenant, Comcast, will complete relocating employees to the new tower by July 2008.

On June 18, 2007, it became the tallest building in Philadelphia and the Commonwealth of Pennsylvania in an official topping-out ceremony led by then Philadelphia Mayor John F. Street.

When the final beam in the construction was raised on June 18, ironworkers of Local Union 401 attached a small figurine of William Penn to the beam in homage to the statue atop Philadelphia City Hall, in an attempt to break the curse of Billy Penn.

Design and construction

Designed by Robert A. M. Stern Architects, LLP, the Comcast Center rises to a height of 975 feet (297 m). The Center has 57 floors, 56 rentable with 1,248,000 square feet (115,900 m²) of office space and about 23,000 square feet (2,100 m²) of retail space. In 2006, the building was valued at $523 million.

The building is situated between Arch Street, 17th Street, 18th Street and John F. Kennedy Boulevard (the building's footprint obliterated a one block section of Cuthbert Street). While its official address will be One Comcast Center Philadelphia, PA 19103-2838, it is located at 1701 John F. Kennedy Boulevard and the tower itself rises on the Arch Street side of the block, due to the Suburban Station concourse and rail tunnel that run directly beneath Liberty Plaza in front of Comcast Center.

Owing to the terracing and idiosyncratic notch, the Philadelphia Inquirer has joked that Comcast built a giant USB memory stick.

Part of the public space includes a new entrance to the SEPTA's Suburban Station with a 120-foot (37 m) high glass-enclosed winter garden. Other features include:

  • multiple three-story stacked atria rising on the south face of the building
  • ½ acre landscaped public park, Liberty Plaza, with a fountain display and an outdoor cafe seating 85.
  • expansion of Suburban Station's underground retail concourse in an area called The Market at Comcast Center
  • 500-seat concourse level dining court
  • 120 private space underground parking garage
  • A giant high-definition video wall in the lobby, standing 25 feet high by more than 83 feet wide
  • Two-story cafeteria ("Ralph's Cafe") on the 43rd and 44th floors
  • new entrance lobby addition to historic Arch Street Presbyterian Church
  • sustainable building design with the goal of achieving a LEED (Leadership in Energy and Environmental Design) rating from the U.S. Green Building Council
  • waterless urinals
