Rarely does a 1.3-acre property become available in the heart of Harwich Center! This 3-bedroom, 2-bath Cape offers an exceptional combination of space, location, and potential. The home features an enclosed porch, a flexible floor plan, and a one-car garage. A separate ADU has been completely gutted and is ready to be finished, offering possibilities for guest accommodations, a home office, studio, or additional living space, subject to town approvals. The expansive lot provides 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 space, versatility, and endless possibilities in one of Harwich's most convenient locations!
