Description
A Rare Boutique Office Condominium in the Heart of Park Slope
An exceptional opportunity to acquire a one-of-a-kind commercial condominium within one of Brooklyn’s most iconic landmark buildings. Originally constructed in 1889 as a Venetian Gothic clubhouse, this architecturally significant property has been thoughtfully reimagined into an elegant boutique office environment that seamlessly blends historic character with modern functionality.
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. Surrounded by Park Slope’s vibrant mix of restaurants, cafés, retail, and cultural institutions, this is a rare opportunity to own a trophy office asset in one of Brooklyn’s most established and sought-after neighborhoods.
