435 Broome Street, a historic and landmarked building, has just hit the market for $17 million. Custom built in 1873 by the great Gothic revival architect William Appleton Potter, 435 Broome Street consists of five impeccably maintained tall loft stories. The building is currently configured as three residential lofts, one commercial loft showroom, over a ground floor retail space, including a lower level with a sub-basement.
