About this home

Ready for Spring 2027 This Exceptional New Construction Modern Chateau Estate in Muttontown is located within the renowned Syosset School District. The Chateau sets a striking new benchmark for refined living. This exquisite 8,000-square-foot residence offers seven bedrooms, 15 rooms and a fresh, contemporary layout designed for today’s most elevated lifestyles. A grand courtyard entrance leads to custom-crafted oversized iron doors that dramatically unveil a breathtaking two-story entry foyer. The formal dining room shimmers and the grand living room is anchored by a commanding two-sided modern fireplace that offers open views of the lush 2 acre property. The bespoke chef’s kitchen serves as a true centerpiece, equipped with premium appliances, designer cabinetry and a spacious layout ideal for both everyday living and large gatherings. A fully equipped scullery kitchen adds an additional layer of convenience and sophistication for those who entertain on a grand scale. The main level further unfolds with guest quarters, a private study, media room and a secondary staircase. Ascending to the primary suite is to enter a private world of luxury with a serene balcony overlooking the property, a spa-inspired bath, refreshment area and expansive walk-in closets befitting the most discerning wardrobe collections. The second level continues with a spacious lounge and four additional en-suite bedrooms, each a haven of comfort and privacy. Outdoor living is equally impressive, with fully approved plans to consider upgrades for a resort-style spa pool and an open-air pavilion. The 10-foot lower level also stands ready to fulfill any vision. The Chateau is not merely a home, it is a residence designed for the discerning, where high-style luxury meets the ease and functionality of everyday living. Meticulously envisioned with master craftsmanship and aesthetic precision that blends seamlessly with classic architectural detailing, light-filled interiors and a seamless flow between indoor and outdoor spaces. Ready to customize. All images virtually rendered to illustrate design possibilities.
