There are a few more details on that condo project that is going to be developed in Gowanus by the Hudson Companies, which built the 33-story J Condos in Dumbo. Last month, we noted the sale of the property at 3rd Street and Bond for $7.75 million. The Brooklyn Eagle reported yesterday that the developer is planning 50 condos in “nine or 10 four-to-five-story townhouse-style buildings” on the property. Rogers Marvel Architects will design the project, according to the Eagle. Demolition on the site is expected within 45 days and the developer plans to start construction so they don’t “miss the amended 421-a tax exemption deadline” of December 31. which is Dec. 31.
