18 Birch Mill Road, Killingworth, CT 06419 (MLS # 24183296)
The Well Maiden Estate is a rare architecturally significant waterfront estate where cascading waterfalls, winding streams, and Kroopa Pond converge across 3.5 private acres to create one of Connecticut's most extraordinary residential settings. Just minutes from the Connecticut shoreline, marinas, beaches, and fine dining, and ideally positioned between New York City and Boston, this private luxury retreat offers a rare opportunity to own a legacy estate equally suited for year-round living or a distinguished second-home escape. Originally a historic fishing shack, the restored wing blends seamlessly with a striking architectural residence designed to embrace its natural surroundings. Soaring vaulted and barreled wood ceilings, walls of glass, rich hardwood and slate floors, and 2 grand living rooms with magnificent fieldstone fireplaces create warm, sophisticated spaces with captivating water views. Chef's kitchen with Garland 6-burner range, double ovens, flat-top grill, Sub-Zero refrigerator, farmhouse sink, pantry, and abundant cabinetry. Four bedrooms include a private upper-level primary suite with exposed beams, waterfront balcony, dressing room, walk-in closet, clawfoot soaking tub, and spa-inspired bath. Heated gunite saltwater pool and spa with waterfall, rare private clay tennis court, bluestone terraces, Viking grilling station, and outdoor shower complete this exceptional estate where architecture, nature, privacy, and luxury exist in perfect harmony.
