For the first time on the market, this sprawling 5,360sf Antique Estate anchored by a 1753 hand-hewn Great Barn and 1773 Manor Home with more recent additions, preserves its 18th-century profile via sophisticated design language and high-efficiency infrastructure. Once home to author Louisa May Alcott's family, "Spindle Hill" originates from the whirr of wheels processing flax for clockmaker Seth Thomas. A striking black & white marble Foyer with soaring cathedral ceiling and 50' windowed turret opens to a show stopping Grand Salon with wide-plank heart-pine floors. The kitchen with white Shaker cabinetry, granite and MacKenzie-Childs hardware flows to a windowed Dining Sunroom and wrapped Trex deck. A Keeping Room with original beehive oven extends to the Carriage House 1st floor primary suite and an In-Law wing. The upper level hosts a 2nd floor Primary Bedroom Oasis with private terrace, while the walk-out finished 1,246sf Garden Level, with 9'-ceiling boasts a cabana bath, grand fireplace lounge (pro recording studio), and wet bar with sparkling water tap. This fortress-grade compound with 3 wood burning fireplaces and 1 gas fireplace insert is protected by an airtight, soy-foam thermal envelope, central AC, 400-amp service, and a Kohler auto-transfer generator. Built as a single-family Mansion, rare legal multi-family zoning allows 3 private dwellings within. Park-like grounds feature a large sunken patio, twin gazebos, gated drive, and turnaround island.
