Description

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., THE CUSTOM RESIDENCE Pristine, sophisticated, and exceptionally well maintained, the custom residence offers five bedrooms and three-and-a-half baths, exquisite inlaid wood floors, abundant natural light, and generously proportioned rooms. The chef's kitchen features premium Wolf and Sub-Zero appliances and opens naturally to the home's light-filled living spaces. The main level also includes a private office, sunroom, elegant dining room, mudroom, and laundry. A separate private entrance leads to an extraordinary recreation/theater room above the garage, currently finished with custom details. This versatile space offers excellent potential as an in-law, au pair, guest, or private suite while providing separation from the principal living areas. The third-floor finished attic provides two additional rooms and a shared full bath. A fully finished lower level adds a dedicated gym plus abundant closets and storage. MODERN EFFICIENCY Recent upgrades include a state-of-the-art solar and geothermal heating and cooling system, delivering exceptional energy efficiency and year-round comfort.
