Exquisite. Exclusive. Exceptional. Homes like 16 Chestnut Lane do not come to market often. One owner since 2005. 5,785 finished square feet of thoughtfully designed living space on 1.72 private acres. Mature, lush landscaping frames the property with the kind of curb presence that takes decades to cultivate. The backyard view will never change - a permanently preserved conservation easement ensures the wooded land behind this property stays exactly as it is today. The main level delivers a two-story family room flooded with natural light, a gourmet kitchen with center island, formal dining room, private study, and Brazilian Cherry hardwood floors throughout. Abundant natural light flows through oversized windows across every level of the home. The curved staircase leads to four bedrooms including a primary suite with cathedral ceilings, a massive walk-in closet, and a spa bath with double vanity, stall shower, and Jacuzzi tub. Two additional bedrooms share a Jack-and-Jill bath. A fourth bedroom has its own ensuite. The fully finished lower level - daylight windows, full bath, and a 45x57 foot open floor plan - functions as a complete third living floor. Three-car garage with epoxy floors. TimberTech deck. The 1.72 acre lot offers ample space for a future pool. Generac whole-house generator serviced August 2026. All four HVAC units replaced December 2021. Hot water heater June 2024.
