About this home

Set on two magnificent acres surrounded by open farmland and natural landscapes, 23 Castle Court is an exceptional Hamptons-inspired country estate offering a remarkable balance of architectural refinement, modern engineering and resort-style living. Thoughtfully conceived and custom-built in 2018 by an accomplished homebuilder, the residence encompasses approximately 8,410 square feet, including its lower level and unfinished spaces, with 4,740 square feet of finished living accommodations. A sophisticated interpretation of the modern farmhouse, the property combines timeless craftsmanship with an extraordinary collection of amenities and advanced residential systems. Gracious interiors unfold beneath 10-foot first-floor ceilings, with wide-plank rift-and-quartered white oak flooring, custom-milled shiplap, recessed paneling and exceptional millwork throughout. A custom masonry fireplace with handcrafted herringbone detailing anchors the gathering spaces, while expansive windows and a dramatic 16-foot Andersen French wood sliding door invite natural light and connect the home to its pastoral setting. At the heart of the residence, a beautifully appointed chef's kitchen showcases custom Ted Wood cabinetry, quartz countertops and a substantial 4-by-8-foot center island with a two-inch-thick butcher-block top. Professional appliances include a 48-inch Wolf six-burner range with griddle and dual ovens, Sub-Zero refrigeration and integrated conveniences. Adjoining entertaining spaces include a dedicated bar room with beverage center, ice maker and access to the rear grounds, complemented by integrated Sonos audio and Dolby surround sound. Five bedrooms and six-and-one-half baths provide generous accommodations, highlighted by a primary suite with private balcony and an elegant marble bath featuring a clawfoot tub, steam shower, custom Ted Wood vanity and Hansgrohe fixtures. The expansive lower level, with 10-foot ceilings, offers a golf simulator that doubles as a home theater, a dedicated fitness area and additional space for future customization. Beyond the interiors, the grounds unfold into a private recreational landscape centered around a magnificent 20-by-50-foot swimming pool with sun shelf, automatic cover and heating and cooling system. Bluestone and Cambridge stone terraces, covered porches with mahogany soffits, a propane fire feature and sweeping lawns create an exceptional setting for outdoor entertaining. A substantial climate controlled three-car garage with a car lift provides versatility for collectors, while an additional detached three-car garage offers flexibility for workshop, recreation or future living improvements, subject to applicable approvals. Equally impressive is the infrastructure supporting the residence. Radiant heating extends throughout the home, basement and garage, with 20 independently controlled heating zones, four-zone central air conditioning, whole-house water filtration and three dedicated reverse-osmosis systems. A 20 kW ground-mounted solar array, 20 kW backup generator and advanced home networking reflect the same attention to performance found in the home's James Hardie siding, Andersen windows and carefully selected exterior materials. A distinguished offering where architectural craftsmanship meets extraordinary technical sophistication, 23 Castle Court presents the privacy of a country estate with the amenities, comfort and infrastructure of a thoughtfully engineered modern residence.
