"We’ve seen countless developments along the North Broad Corridor and within the Callowhill loft district during the most recent development boom in Philadelphia. So many that we haven’t had a chance to write about each and every one of them. Needless to say, North Broad is rising. Callowhill’s development is fueled by the new Rail Park community space, the neighborhood’s proximity to the core of Center City, its transit accessibility, and its amazing industrial building stock.
Today, we bring you the gigantic surface parking lot at 1306-1334 Callowhill St., which is owned by the notorious Philadelphia parking moguls at Parkway. This 34,233 SF CMX-4 lot sits just a half block from Broad St. and the Callowhill subway station. Although this parking lot is overwhelmingly large in its current state, it used to be much bigger. Up until about 2015, this sea of asphalt stretched all the way to Broad St. and even across Broad St. another half block. Parkway partnered with a Texas-based development company to build the Hanover North mixed-use project on the full lot west of Broad and roughly half of the lot on the east side of Broad. The other half of the lot east of Broad is the site we are looking at today."
