Welcome to a rarely available terrace-level luxury studio in the iconic waterfront cooperative Harbour Square.
This sun-filled residence features custom built-ins and a thoughtfully integrated Murphy bed system that maximizes both style and function. The contemporary kitchen is appointed with flowing granite countertops, sleek cabinetry, and an open layout ideal for everyday living and entertaining.
A dramatic 12-foot sliding glass wall opens to an extraordinary 420-square-foot private terrace (approximately 26’ x 16’) — one of the largest in Harbour Square — offering prized southern exposure and serene courtyard views. This expansive outdoor space provides true indoor-outdoor living rarely found in studio residences.
Interior highlights include new wood flooring, mirrored closet doors, abundant storage, and the convenience of an in-unit stacked washer and dryer.
Harbour Square’s celebrated mid-century modern architecture is complemented by sweeping rooftop water views and beautifully landscaped grounds along the Washington Channel. Residents enjoy 24-hour gatehouse service, high-speed internet, indoor pool, fitness center with floor-to-ceiling glass, EV charging stations, and access to secure garage parking (available for rent at $155/month).
Ideally located adjacent to The Wharf, one block from Waterfront Metro, and moments to the National Mall, Capitol Hill, Nationals Park, and Fort McNair, this address offers the perfect balance of vibrant city access and peaceful waterfront retreat.
The monthly cooperative fee of $1,047 includes utilities, property taxes, internet, and full access to community amenities.
