After buying 71 Stuyvesant Avenue in the part of town Corcoran is calling Bedwick (Bed Stuy meets Bushwick, get it?) in 2010 for $640,000, the new owner set about renovating the walkup building; in retrospect that looks like a great price for a 6,200-square-foot building in this rapidly changing area. After two and a half years, the project was ready for its unveiling yesterday. At an open house yesterday, the twelve units, ranging in price from $1,650 for a 450-square-foot studio to $3,950 for a 1,800-square-foot four-bedroom, were shown for the first time. Every apartment has central air and heat and there’s a shared laundry facility in the building. Update: We’re hearing that about a dozen people showed up to the open house yesterday.
