Comcast Center, also known as the Comcast Tower, is a skyscraper at 1701 John F. Kennedy Boulevard in Center City, Philadelphia. The 58-story, 973-foot (297 m) tower is the second-tallest building in Philadelphia and in the U.S. Commonwealth of Pennsylvania, and the 31st-tallest building in the United States. Originally called One Pennsylvania Plaza when plans for the building were announced in 2001, the Comcast Center went through two redesigns before construction began in 2005. Comcast Center was designed by Robert A.M. Stern Architects for Liberty Property Trust.
In early 2005, the final redesign and its new name—the Comcast Center—were unveiled. The building is named after its lead tenant, cable company Comcast, which makes the skyscraper its corporate headquarters. Leasing 1,094,212 square feet (101,656 m), Comcast takes up 89 percent of the building. The building features retail and restaurant space and a connection to Suburban Station which is nearby. In Comcast Center's lobby is the Comcast Experience, which is a 2,000-square-foot (190 m) high-definition LED screen that has become a tourist attraction. Designed to be environmentally friendly, the skyscraper is the tallest Leadership in Energy and Environmental Design (LEED) certified building in Philadelphia.
