The residence

A rare Harwich Center property with space to live, work, create, and tinker! Set on approximately 1.5 acres, this unique offering includes a 6-bedroom main home, separate ADU with its own private driveway and strong rental history, plus a detached mixed-use garage with serious potential. Auto enthusiasts, collectors, contractors, tradespeople, hobbyists, or anyone dreaming of their own workshop will appreciate the space for vehicles, tools, equipment, projects, and storage. The flexible living arrangement also lends itself to multigenerational living, extended family, guests, or potential employee/workforce housing. Outside, a spacious landscaped backyard, multiple sheds, and fire pit create even more possibilities—think additional workshop space, art studio, home bar, hobby room, or private retreat. Whether you're looking for income potential, room for your passion projects, or a property that can accommodate both living and working, this is anything but ordinary!
