PHILADELPHIA — Comcast Corp. already built the tallest skyscraper in Philadelphia. On Wednesday, it revealed plans to build an even taller one.
The Philadelphia-based media giant said it plans to build a $1.2 billion, 59-story technology center that will rise 1,121 feet next to the existing Comcast Center, which stands 975 feet tall.
Comcast Corp. and real estate investment trust Liberty Property Trust said the Norman Foster-designed glass and stainless steel tower would become the ‘‘dedicated home’’ for its expanding workforce. It will also boast a media center in the heart of downtown Philadelphia that will be home to the region’s NBC affiliate, WCAU-TV, and Telemundo’s WWSI-TV.
Comcast Corp. is the largest global media and technology company and owns NBC Universal. Full story for BostonGlobe.com subscribers.
