The Well Maiden Estate is an 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. Positioned between New York City and Boston and minutes from the Connecticut shoreline, 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.

Soaring vaulted and barreled wood ceilings, walls of glass, rich hardwood and slate floors & 2 grand living rooms anchored by magnificent fieldstone fireplaces create warm, sophisticated spaces w/ captivating water views throughout. The chef's kitchen is appointed with a professional Garland six-burner range, double ovens, flat-top grill, Sub-Zero refrigerator, farmhouse sink, pantry, and abundant cabinetry. 4 bedrooms provide flexible accommodations, a private upper-level primary suite featuring exposed beams, a waterfront balcony, dressing room, walk-in closet, clawfoot soaking tub & spa-inspired bath.
