In February, Philly YIMBY published an examination of the Twin Independence Blue Cross Tower proposal that was planned in the mid-1980s. The Independence Blue Cross Tower were designed by WZMH Architects, who also designed the CN Tower in Toronto, Canda. The developer, The Linpro Company, intended to build two 45-story towers on the 1900 block of Market Street. Each would have stood 625 feet tall, located 1901 Market Street and 1919 Market Street in Center City. If built as a twin pair, they would have stood next to the 565-foot Commerce Square towers, another pair of twin high-rises.
The last publication had only featured 3D models of the twin towers on the massing of the Philadelphia skyline, rendered to match the time period when the Mellon Bank Center and Two Liberty Place had just wrapped construction. Speaking of those two towers, Linpro was attempting to build the second twin while Mellon Bank Center and Two Liberty Place were rising. But the attempts turned out to go no where as the tenants that had signed on to the tower had backed out, leaving the site as a dirt lot until it was developed by Brandywine Realty Trust as a residential building at 1919 Market Street.
In the lifelike renderings of the towers, we can observe that the glass towers would have made the skyline look slightly more massive. The proposal would also make the skyline look more modern as the tower is completely covered with glass on the upper office floors, with stone located at the base.
