Two original units combined into one expansive home. A rare private terrace, balconies stretching along the entire length of the residence, and the space to spread out. This two-bedroom, two-bath home at Harbour Square brings together a flexible floor plan, indoor-outdoor living, and all-inclusive cooperative convenience in the heart of Southwest Washington.



Five sets of floor-to-ceiling sliding glass doors fill the home with natural light and provide seamless connection to the outdoors. A welcoming entry foyer with a large hall closet opens into the expansive living and dining spaces, with generous proportions reflecting the home’s combined floor plan. Renovated in 2023 and refreshed in 2026, the home features fresh paint, new luxury designer LVP flooring in the main living areas and second bedroom, and a streamlined kitchen with ample cabinetry, expansive counters, and a full suite of smart appliances. The primary suite offers a private balcony, a custom walk-in closet with room for an office or sitting area, and a spa-inspired en-suite bath with heated floors, a waterfall shower, and smart features. A second bedroom, second full bath, and in-unit washer and dryer complete the interior.



Outdoor living is a defining feature, with a substantial terrace opening directly from the living room and additional balconies accessed from the living room, dining room, and bedrooms. Together, the terrace and balconies provide ample room for dining, entertaining, gardening, and enjoying the surrounding Waterfront setting.



Designed by renowned Washington architect Chloethiel Woodard Smith, Harbour Square is a landmark of mid-century modern architecture set across six landscaped acres along the Washington Channel. Residents enjoy 24-hour gatehouse security, a renovated heated indoor pool, a state-of-the-art fitness center with river views, rooftop decks with panoramic views of the water and city skyline, and lush, award-winning gardens, as well as a library, meeting spaces, and a large party room. Garage and covered parking ($165/month), bike storage, and EV charging are available on-site. Pets are welcome. The all-inclusive monthly cooperative fee of $2,542.42 covers property taxes, all utilities (electricity, gas, water, trash and recycling), Xfinity cable, high-speed internet, operating costs, and capital reserves.



Just two blocks from Waterfront Metro and steps to The Wharf’s dining and entertainment, #S430 & #S429 at Harbour Square offers the best of Southwest Waterfront on a larger scale.
