Last week, Philadelphia YIMBY looked at a new proposal for an eight-story mixed-use building slated to rise at 1527 Callowhill Street in the Franklintown neighborhood in Lower North Philadelphia. The development will replace a parking lot at the northeast corner of Callowhill and North 16th streets with a 208,000-square-foot structure that will incorporate 188 rental residences, ground-level retail, parking for 24 cars and 63 bicycles, and a sizable green roof. Today we assess the development’s technical details and conceptual blueprints as presented to the city’s Civic Design Review committee in a submission by the project team, which includes Omega Home Builders as the developer and Designblendz Architecture as the designer.
