Description

Down a perfectly manicured private road, discover 171 Oneck Lane - a newly constructed, estate (built by ONE DEVELOPMENT) that captures the essence of refined Hamptons living. Ideally situated on just under an acre, the property overlooks the prestigious Westhampton Beach Country Club; offering sweeping views across the lush fairways of the 3rd hole-delivering both privacy and an elevated golf setting. Designed with meticulous craftsmanship and focussed on both scale and comfort, the home offers 7 en-suite bedrooms and 11 well appointed bathrooms. A grand foyer introduces a spacious, light filled open concept layout with soaring ceilings, custom millwork, coffered ceilings and elegant moldings throughout. A private side entrance with a grand mudroom, and walk in pantry, offering effortless access and everyday functionality, complemented by the attached two-car garage. The chef's kitchen is both striking and functional, featuring a full slab Quartz backsplash and oversized island with seating, and top-tier paneled appliances by Wolf, Sub-Zero and Bosch. Seamlessly connected living and dining spaces are designed for effortless entertaining, with expansive glass sliders that invite natural light and open to the outdoor living areas. A double sided gas fireplace anchors the main living space and extends into a sophisticated lounge with a built-in bar. A first floor junior primary suite provides ideal guest accommodations with its own private bath. Beautifully detailed main and back staircases lead to all three levels. The second floor includes the primary suite- a true retreat; stunning sunsets and golf course views, a private balcony, fireplace, dual walk-in closets, with french doors and a center island, a spa inspired bath with a double vanity, soaking tub, large format slab shower, and water closet. There are four additional en-suite bedrooms, including one with a private balcony and a charming bunk room with it's own sitting area. A large laundry room with dual washers and dryers complete this level. The fully finished lower level is designed for both relaxing and entertainment featuring a recreation room with a built-in bar, Sub-Zero refrigeration, and XO ice maker, along with areas for billiards and games. A private home theatre with six reclining chairs creates a true cinematic experience. Wellness amenities include a fitness center, Clearlight sauna, changing room and full bath. An additional en-suite bedroom with bath and a powder room provide comfort and convenience for guests. Outdoor living is equally exceptional. Step outside to a resort style backyard oasis. A heated gunite pool with sun ledge and integrated loungers, along with a built-in spa is surrounded elegant stone patios and lush landscaping. The outdoor kitchen is fully equipped with a built-in BBQ, refrigerator, ice maker, and a recessed drop-down TV, and ceiling heaters for extended seasonal use. There are multiple covered patio areas with recessed lighting, fans and speakers. A private putting green and beautifully curated grounds with speciman trees, flowering shrubs & hydrangea, and a private courtyard complete this offering. This is a rare opportunity to own a newly built, fully amenitized estate in one of Westhampton Beach's most desirable locations, offering the perfect balance of luxury, lifestyle, and setting.
