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 current property encompasses two separate building lots. The main house is on 2.4 acres, and the adjacent 1.9 acre lot may be purchased in addition to this home. 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. 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.
