The District at 15fifteen

The District at 15fifteen is a mixed-use, market-rate development along Route 10 in Parsippany, NJ, that is revitalizing the former site of a 290,000-square-foot office campus with a walkable town square. The site will contain 498 luxury apartments, 58,600 square feet of retail and restaurant space, and a Residence Inn by Marriott.
