Harbour Square is a mid-century high-rise condominium/co-op complex completed in 1966 and sited directly on the Washington Channel. The development features long horizontal massing with multiple towers and low-rise elements organized around landscaped courtyards, water features, and extensive hardscape. Typical homes are three-bedroom layouts averaging large floor plates with formal living and dining areas, multiple balconies, and large expanses of glass that frame river, channel and monument views. Interiors commonly include hardwood floors, crown moldings, updated kitchens (island or gourmet configurations), walk-in closets, spa-like primary baths, built-ins, recessed lighting and in-unit laundry in many residences. Shared building resources emphasize leisure and convenience: a staffed lobby, fitness room, heated indoor pool, library, roof terraces, multiple gardens and walking paths, plus bike storage and additional storage rooms. Parking includes rental and guest parking options and some extra parking availability. The property is pet-friendly and offers services such as 24-hour desk/concierge in full-service sections, trash removal and on-site management. Its waterfront location places residents steps from The Wharf boardwalk, shops, restaurants, Waterfront Metro and easy access to downtown, Capitol Hill, Navy Yard and regional connections.
