The chef's kitchen is truly a culinary masterpiece, featuring three sinks, Wolf, Subzero, and Kalamazoo appliances, a butler's pantry, a wet bar, custom white oak cabinetry, and a stunning Tuscan-white waterfall marble island. The dining area boasts a center fireplace opposite the breakfast nook, overlooking the breathtaking nature preserve.

Step outside into the screened-in porch, where eight operable skylights illuminate the space. The outdoor kitchen, equipped with a Kalamazoo BBQ and wine storage, perfectly complements the picturesque pool area. Enjoy serene views of the protected forest and glimpses of nearby horse pastures from the terrace, with access to the sparkling gunite pool and newly constructed white stone patio.

Retreat to the regal primary suite, featuring vaulted ceilings, a large sitting room/home office, double bathrooms and dressing rooms, a steam sauna, a power shower, and a therapeutic whirlpool tub. Additional luxurious amenities include a saltwater hot tub, a dry sauna, multiple fireplaces, and seven zones of central air and hydronic radiant floor heating throughout.

The connected pool house serves as a sanctuary, complete with a cedar sauna, workout area, and a king-size master en-suite bedroom with direct patio access. The finished basement offers ample entertainment space, including a screening room, lounge, and billiards area.

This gated flag lot, perched atop a hill, ensures privacy and tranquility, enhanced by security cameras and custom night lighting. The three-stall heated garage and private motor court comfortably accommodate up to 20 vehicles.

Experience the best of both worlds with this exceptional property—just 90 minutes from Midtown Manhattan, eight minutes to Southampton Village, and 10 minutes to Flying Point Beach.
