COMCAST INNOVATION AND TECHNOLOGY CENTER BY FOSTER + PARTNERS

Comcast Corporation (Nasdaq: CMCSA, CMCSK) and Liberty Property Trust (NYSE: LRY) announced today they will jointly develop the “Comcast Innovation and Technology Center” on the 1800 block of Arch Street in Center City Philadelphia, USA.

The proposed $1.2 billion 59-story, 1,121-foot tower will neighbor Comcast Center, Comcast Corporation’s global headquarters, and become a dedicated home for the company’s growing workforce of technologists, engineers, and software architects.

The facility will also create a media center in the heart of the City by becoming home to the operations of local broadcast television stations NBC 10/WCAU and Telemundo 62/WWSI and offer space for local technology startups.

Designed by world-renowned architect Lord Norman Foster of Foster + Partners, the glass and stainless steel tower will complement Comcast Center as a new energetic dimension to Center City. The 1.517 million rentable square foot project will include a new Four Seasons hotel and a soaring, block-long lobby with a glass- enclosed indoor plaza accompaniment to Comcast Center’s existing, dynamic outdoor plaza.

The lobby will feature a restaurant and a new concourse will provide direct connections with SEPTA’s Suburban Station, enhancing accessibility and providing new options for commuters. The $1.2 billion mixed-use tower is expected to be the tallest building in the United States outside of New York and Chicago and will be the largest private development project in the history of Pennsylvania.
