"THE GULPH" is a rarely offered, by-right mixed-use development opportunity in the heart of King of Prussia, Pennsylvania — the #1 suburban Philadelphia apartment submarket. This ±2-acre assemblage in Montgomery County features three contiguous parcels (87,120 SF), zoned NMU (Neighborhood Mixed-Use), supporting a 32-unit development program across two (2) buildings totaling ±51,000 SF of construction via 3-story architecture — no rezoning required. The conceptually approved plan calls for Building 1 (657 & 665 S. Gulph Rd) to deliver a ±40,000 SF mixed-use structure with 21 apartment units, ±5K SF ground-floor commercial space, and 11 under-building parking spaces. Building 2 (671 S. Gulph Rd) adds ±11,000 SF with 10 residential units and a 15-space parking expansion. The total program yields 32 units (25 x 1BR / 6 x 2BR), ±5,000 SF of NNN retail, and 65 total (covered and surface) parking spaces. Utilities are already at the site. Located at the crossroads of I-76, I-276, US-202, and Route 422 with quick access to the King of Prussia/Valley Forge corporate corridor, King of Prussia Town Center, Valley Forge National Historic Park, Netflix House, TopGolf, Life Time, KOP Mall (Top-5 in USA) and 60,000+ daytime workers, the submarket commands MSA-leading occupancy (95.4%).
