Harbour Square is an eight-story mid‑century residential complex completed in 1966 and noted for its low horizontal massing and expansive landscaped grounds. The property contains a mix of generously proportioned cooperative residences—many configured as two‑bedroom, two‑bath “through” units with dual exposures—and offers mid‑century details such as built‑ins, crown moldings, and original design elements alongside modern updates like gourmet kitchens and refurbished baths. Common interior features include elevators, laundry facilities, formal dining spaces, wet/dry bar areas, hardwood floors, and varied floor plans that range from open to traditional. Shared amenities are robust: indoor heated lap pool, fitness center, public rooftop decks with panoramic city and river views, club/meeting rooms, hobby and storage spaces, bike lockers, and guarded package handling. The exterior setting emphasizes landscaped open space with a one‑acre aquatic garden, lawn areas, play facilities, roof terraces, sidewalks, exterior lighting, and secure storage; garage parking is available for rent and guest parking is also offered. The building is pet friendly and provides on‑site management and a staffed gatehouse. Located on the Southwest Waterfront, Harbour Square sits within walking distance of Waterfront Metro, Wharf attractions, Nationals Park, Arena Stage, and water taxi access, combining a park‑like site with easy access to urban cultural and transportation nodes.
