About this home

Set on a spacious 1.3-acre lot in desirable Harwich Center, this 3-bedroom, 2-bath Cape offers exceptional space, versatility, and potential. The home features an enclosed porch, a flexible floor plan, and a one-car garage. An additional detached one-bedroom ADU has been completely gutted and is ready to be finished—ideal for guest accommodations, extended family, a home office, studio, or potential rental income, subject to town approvals. The expansive lot offers plenty of room to create a private outdoor retreat, with potential for a pool or future expansion. Ideally located near Brooks Park for pickleball and recreation, the Cape Cod Rail Trail, Harwich Center shops and restaurants, and the beaches, dining, and boutiques of Harwich Port. A unique opportunity with endless possibilities in the heart of Harwich!
