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.
