The condo with the working name of The Gowanus, which is on First Street in Park Slope, has shown its face this week. It is the building we have sometimes called the Big Mac Building, because it adjoins a McDonald’s on the corner. The building in the photo below, meanwhile, is a neighbor that doesn’t serve McMuffins. The structure is 267 First Street, which was designed by Robert Scarano. It was hit by a Stop Work Order in early 2007 that was only lifted on February 28, so it has had the look of an abandominium for a long time.
