Yes, condos in the Imlay Street New York Dock building are hitting the market already, despite a projected 2016 completion date. You can buy a one-bedroom loft (3,429 square feet) for the strangely precise sum of $3,857,325.
Hopefully the luxury rehab center ($50,000 per month, anyone?) and the delayed-opening private school ("The Best Schools in America Have Arrived in Brooklyn") will be up and running by then. The wine shops and boutiques along Van Brunt are already coming along quite nicely.
