A rare offering with over 1100 square feet of outdoor space on every level, in a premier new development-this penthouse is a true showstopper. 684 Dean is a boutique, 5 unit new development in trendy Prospect Heights, with easy access to the Farmer's Market at Grand Army Plaza, Prospect Park, and the Brooklyn Botanic Gardens.
