Rare new construction in Harwich Port. Set back on a long private drive, this brand-new estate pairs a 4-bedroom main house with a detached guest/pool house, built for multiple generations and summers that never have to end. Inside, dueling primary suites, one on each floor, give grandparents, guests, and kids their own retreats, with the first-floor suite opening to a private deck. The open kitchen, living, and dining plan showcases 9’6″ ceilings, white oak floors, a coffered living room, and a Calacatta quartz island, plus a first-floor office for working from home. Upstairs, a family room with wet bar and deck access adds another place to gather, and a walkout basement is plumbed for a future bath. Then everything leads outside to the true heart of the property: an expansive, fully fenced backyard with beautifully landscaped grounds and a sparkling pool. Anchoring it all, the guest/pool house offers a garage and a “wet room” built for hosting all summer long. Pella windows and quality finishes carry through every room. Brand-new homes this close to Harwich Port’s beaches, shops, and restaurants rarely come along, and this one is ready to welcome its first family.
