Comcast Corp., which runs its growing media empire from Philadelphia’s tallest skyscraper, is considering building at least one new tower in Center City and is working with the prominent British architect Norman Foster, according to sources in the city’s real estate community.
Details about Comcast’s expansion plans are being kept under tight wraps, but the company appears to be focusing on constructing the first of several towers on a long, skinny, 1.5-acre site at 18th and Arch Streets, a block west of the Comcast Center. That building could eventually be part of a vertical campus including towers at 19th Street and Arch, and 18th and John F. Kennedy Boulevard.
All three sites are controlled by Liberty Property Trust, which completed Comcast’s sleek, 975-foot headquarters just six years ago.
Since then, Comcast has grown enormously. With its acquisition of NBCUniversal and its move into new digital products, Comcast has filled virtually all 1.2 million square feet in its glass obelisk and needs more office space for its expanding workforce.
