About this home

Steeped in architectural pedigree and timeless elegance, this extraordinary Muttontown estate, on 3.84 bucolic acres, was designed by renowned architect Marion Sims Wyeth. Privately tucked behind an impeccably landscaped half mile-long drive off Route 106, the property unfolds as a secluded North Shore sanctuary of exceptional beauty and distinction in the acclaimed Syosset School District. Set amidst sweeping lawns, manicured gardens, and picturesque equestrian grounds, the stately brick residence, crowned with a slate roof and introduced by a charming courtyard entry, exudes enduring sophistication. Inside, grand formal entertaining rooms showcase exquisite millwork, original hardwood floors, dramatic wrought-iron railings, and an abundance of French doors that flood the interiors with natural light while seamlessly connecting the home to its breathtaking surroundings. Offering five bedrooms and five-and-a-half baths, the home masterfully balances grandeur with comfort. The formal living room, complete with a fireplace and built-in wet bar, creates an inviting setting for entertaining, while the sunlit breakfast turret and updated chef’s kitchen, appointed with premium professional-grade appliances, provide effortless everyday functionality. A spacious family room and elegant powder room complete the main living spaces. The first-floor primary suite serves as a luxurious private retreat, featuring dual full baths, a fireplace, expansive walk-in closets, and an intimate sitting room. The upper level offers two generously proportioned bedrooms and a beautifully appointed full bath with a thoughtfully separated vanity and shower area. Completing the space is an expansive unfinished attic, presenting exceptional potential for storage or future customization. Additional highlights include a walk-out finished lower level with laundry, bedroom with full bathroom and direct access to the attached two-car garage. Designed for both gracious living and sophisticated entertaining, the residence boasts expansive slate terraces spanning the length of the home, overlooking the stone courtyard driveway, private gardens, charming pergola, and in-ground gunite pool - evoking the romance and refinement of a storybook North Shore estate. A true horse property, the fully fenced equestrian amenities are equally exceptional, featuring a pristine multi-stall barn built-by Morton, thoughtfully designed grazing paddocks, and scenic walking trails woven throughout the grounds. A truly rare offering, this remarkable estate presents an unparalleled opportunity to own a significant piece of Long Island history.
