About this property

Located in the heart of Westhampton Beach Village, this extraordinary 9,500-square-foot estate is set on 1.20 beautifully landscaped acres, offering a rare blend of historic grandeur, modern comfort, and the quintessential Hamptons lifestyle. Rich in character and timeless elegance, the residence is introduced by a grand foyer that immediately sets the tone for the home's impressive scale. Beyond, an oversized historic ballroom serves as the centerpiece of the estate, featuring soaring ceilings, a wood-burning fireplace, floor-to-ceiling windows, and custom built-in bookshelves. Originally dating to the 1800s, this remarkable space is steeped in history and craftsmanship, with rich walnut millwork and architectural details that make it truly exceptional. Evoking the glamour and sophistication of the Great Gatsby style, the ballroom is an extraordinary setting designed for unforgettable entertaining and effortlessly accommodating everything from intimate gatherings and elegant dinner parties to grand-scale celebrations and lavish soirees. The main level offers a spacious living area, billiard room, full bath, an additional living space complete with a kitchenette and bar and a bedroom with en suite bath. An oversized formal dining room and separate breakfast area provide exceptional settings for hosting, while the den/great room, anchored by a wood-burning fireplace, creates a warm and inviting retreat. The chef's kitchen is appointed with granite countertops, maple cabinetry, an induction oven, and stainless-steel appliances. A laundry room and powder room complete the first floor. The second level is thoughtfully arranged into two distinct wings. The west wing guest quarters feature an own foyer leading to a full bath, sitting area, and bedroom. This wing also includes an office opening to an own balcony overlooking the beautifully manicured grounds, along with a sitting room, full bath, additional bedroom, and balcony access. The main second-floor wing showcases an expansive primary suite designed as an inclusive sanctuary, featuring a spacious sitting room, wood-burning fireplace, walk-in closet, spa-inspired bath, and a dramatic spiral staircase leading to a lofted retreat. An additional office completes this wing. A second primary suite offers its own sitting area and en suite bath, providing luxurious accommodations for all. Blending timeless Hamptons elegance, architectural character, and exceptional scale for both grand entertaining and private living, this distinguished estate presents a rare opportunity to own one of the area's most unique residences.
