Listing details

Originally created by combining two residences, this expansive two-bedroom, two-bath home at Harbour Square offers substantial living space, extensive outdoor areas, and a flexible floor plan in the heart of Southwest Washington.<br><br> The living and dining areas are lined with multiple sets of floor-to-ceiling sliding glass doors, filling the home with natural light and creating a seamless connection to the outdoors.
