WELCOME to 21 CLARKSON LANE. Set at the end of a coveted cul-de-sac and surrounded by approximately five acres of extraordinary privacy, 21 Clarkson Lane is a rare Connecticut estate offering an exceptional combination of refined living, resort-style amenities, and remarkable future possibilities. The property encompasses two separate building lots, including an approximately 1.9-acre approved buildable lot that is already established and does not require subdivision. Whether envisioned for a future residence, guest house, equestrian use, tennis court, additional acreage, or simply treasured open space, this offering provides a level of flexibility seldom found in the marketplace. A CONNECTICUT COUNTRY SETTING Stone walls, pastoral views, mature landscaping, and exceptional privacy create an idyllic country retreat. The grounds have been thoughtfully designed for both everyday enjoyment and memorable entertaining. A spectacular pool, new bluestone patio, and beautifully appointed outdoor kitchen create a private resort-like environment. A large fenced garden offers abundant space for fruits and vegetables, complemented by an established orchard. The impressive multi-purpose barn adds another dimension-ideal for outdoor toys and equipment, or easily imagined as a studio, pool house, game room, workshop, or creative retreat.
