By this time next year, the Williamsburg waterfront will have four residential towers in some stage of completion–two at Northside Piers, which is a Toll Brothers venture, and two at the Edge, the big complex to the north. Phase I of the Edge will have 575 luxury units and 347 affordable units. There will also be about 100,000 square feet of retail space. The buildings are rising at two stories per week and a topping off of the first twoer is planned by November. About 500 workers are on the site every day. We had a full photo gallery at Curbed yesterday.
