Comcast Innovation and Technology Center, Philadelphia, United States of America


The Comcast Innovation and Technology Center is a 59-storey, 1,121ft high mixed-use tower being developed jointly by Comcast and Liberty Property Trust. The project will be 80% owned by Comcast, while Liberty Property Trust will hold the remaining 20% interest and manage the new facility.
The tower will come up on the 1800 block of Arch Street in Center City, Philadelphia, and will be located right next to Comcast's global headquarters, Comcast Center.

The main architect for the project is Lord Norman Foster of Foster + Partners. The building is designed to attain LEED Platinum certification from the US Green Building Council. Construction will start in the middle of 2014, and is expected to be completed by 2017 at an estimated cost of $1.2bn.

The new skyscraper will primarily cater to technologists, engineers and software architects of Comcast. It is also touted to become a media centre for the city by housing local television stations such as NBC 10/WCAU and Telemundo 62/WWSI, besides providing space for start-up and early-stage technology firms and integrating a Four Seasons hotel.

Design features of Comcast Innovation and Technology Center

The tower is constructed of stainless steel and glass facade, will be the tallest building in the United States outside New York and Chicago. It will provide a rentable space of 1.5 million square feet including 1.285 million square feet of office space, 230,112 square feet of hotel space, and 2,682 square feet of retail space.

The tower's glass facades will be heightened by a series of 13 three-storey sky gardens ascending through the eastern elevation, which will depict a continuous pattern of greenery through the building.

"An all-glass elevator will be located along the tower's exterior on 19th street."

The ground level will blend in with the city, opening the building to the public. The lobby will be a block long, with a glass-enclosed indoor plaza merging with the Comcast Center's existing outdoor plaza. It will feature a restaurant, and an underground commuter concourse connected directly to SEPTA's Suburban Station and Comcast Center.

The vertically-stepped tower will feature loft-like office spaces and television studios above the ground level. The 12-storey Four Seasons hotel above the office spaces and studios will feature 200 rooms in addition to a spa, fitness, event and meeting facilities. The apex of the tower will comprise the hotel lobby, a restaurant and bar, and will provide a 360° view of the city. An all-glass elevator will be located along the tower's exterior on 19th street.
