Occupying the lower level of the landmarked building, the space features fourteen private offices, two shared conference rooms, a fully equipped kitchen, and a comfortable tenant lounge. Original hardwood floors, rich oak millwork, stained-glass accents, and operable windows create a distinctive work environment that stands apart from conventional office and coworking spaces. Currently configured as a fully occupied executive office suite with flexible lease arrangements, the property offers immediate income potential while providing future flexibility for investors or owner-users. Its boutique office model has consistently attracted strong demand and long-term tenant interest. Perfectly positioned adjacent to Grand Army Plaza and Prospect Park, the property enjoys outstanding accessibility via the 2, 3, B, and Q subway lines, as well as several major bus routes.
