Property Description
The main level showcases radiant porcelain tile, coffered ceilings, and custom millwork throughout. The kitchen is a true showpiece, featuring two oversized islands with seating and storage, marble countertops, paneled Sub-Zero appliances, a Wolf range and ovens, farmhouse sink, pot filler and more. A formal dining room with wet bar and herringbone floors complements the space, while a powder room finished in striking black marble adds a dramatic touch.
The expansive living and entertaining areas flow seamlessly to the outdoors through French doors, opening to a porcelain-tiled patio and a heated Gunite saltwater pool with automatic cover, integrated spa, and lush surroundings. The home includes a full house generator powered by two 1,000-gallon propane tanks, three-zone HVAC, a space for a future elevator, and smart home wiring for speakers, alarm, and surveillance.
Upstairs, the primary suite offers a private balcony, dual walk-in closets, and a spa-quality bath with double vanities and Toto fixtures. A junior suite with a Juliet balcony offers additional luxury, while a second-floor laundry room and central vacuum with hidden hose system provide modern convenience. All bedrooms feature en-suite baths, with elegant grey, white, and black marble finishes carried throughout.
Additional highlights include a three-car garage with room for car lifts, a mudroom entry, baseboard outlets, flush floor vents, and a 300-pound chandelier motor lift. The home is clad in limestone stucco and brick, with black iron doors and Pella windows offering a sleek, modern exterior. A rare offering in Muttontown—luxury, privacy, and craftsmanship converge at 20 Knollwood Road.
