About this home
Nestled at the end of a private cul-de-sac in prestigious Muttontown, New York, this magnificent four-bedroom, four-bathroom Colonial sits proudly on two lush, beautifully manicured acres within the Syosset School District. A long, scenic driveway framed by tall Green Giant hedging leads to a breathtaking grand foyer, custom archways, and exquisite ceiling details. The main floor features a dramatic, double-sided natural stone fireplace connecting the formal living room and cozy den, alongside a premium chef's kitchen equipped with a custom copper hood, gas cooktop, and warm radiant heated flooring. For maximum efficiency, a highly functional mudroom entrance offers an abundance of storage to match the deep closets throughout the layout. The upstairs layout is reserved for private relaxation, highlighting a dedicated second-floor laundry room and a luxurious primary bedroom suite boasting expansive walk-in closets and a custom steam shower with radiant heat. The expansive, fully finished basement features a dedicated home gym while still leaving massive additional space for recreation, a media area, or leisure, complete with a code-compliant egress window. The resort-style backyard is an entertainer's dream, featuring a heated in-ground pool with a propane heater, sprawling grounds with ample room for a tennis court, and a spectacular covered backyard portico. Premium infrastructure includes a whole-house Cummins generator, 4-zone climate control, an electric car charging port, buried utility lines, and a newer roof (less than two years old) that covers specifically the primary bedroom section and the backyard portico.
