A HOME. A CHAPTER.
A place in our portfolio.
An extraordinary life begins here - A true luxury masterpiece, this extraordinary estate offers over 12,000 square feet of impeccably finished living space, gracefully positioned on five acres of private, manicured grounds. Designed for those who demand excellence, the residence blends timeless architectural elegance with modern amenities of the highest caliber, creating a lifestyle of sophistication and tranquility rarely found at any price point. From the moment you enter the grand foyer, soaring ceilings, eight-foot solid doors, and exquisite millwork set the tone for the refined craftsmanship that defines every room. The main level is designed for both lavish entertaining and intimate living, anchored by an impressive executive office finished with custom woodworking, coffered ceilings, built-ins, and a gas fireplace. The family room is equally captivating, appointed with intricate base and crown moldings, a wood-burning fireplace, and three sets of French doors opening to the expansive bluestone terrace, seamlessly blending indoor and outdoor living. A parlor or piano room also spills onto the terrace through French doors, while the sun-filled living room offers a gas-burning fireplace and additional sets of French doors leading outside. The breakfast room overlooks the grounds and connects to a chef’s kitchen of exceptional scale, featuring a large center island, dual Viking wall ovens, Viking gas cooktop, Sub-Zero refrigeration, two dishwashers, and a fully outfitted butler’s pantry with wet bar and wine refrigerator. A formal dining room, a private guest bedroom with en-suite bath, and a full laundry room complete the main level with effortless function. An elegant staircase leads to an opulent primary suite designed as a private retreat, offering a sitting room, tray ceiling, dual walk-in closets, and a spa bathroom with steam shower, Jacuzzi soaking tub, and radiant heated floors. Additional accommodations include two bedrooms both with an en-suite bath, and one with a walk-in closet, and two additional bedrooms with walk-in closets connected by a Jack-and-Jill bath featuring both a walk-in shower and separate soaking tub. A spacious second-floor living room adds further versatility and comfort. The walkout lower level is a destination unto itself—an entertainer’s universe featuring a movie theater, gym room, 500-bottle temperature-controlled wine room, billiards room, game room, memorabilia room, and a large living room with a wood-burning fireplace. A full bathroom, half bathroom, cedar closet, and abundant storage enhance the functionality of this spectacular space. The resort-inspired exterior rivals world-class vacation properties, offering a sweeping bluestone terrace, a heated saltwater gunite pool framed by a brick patio, and two beautifully designed cabanas—one with a full kitchen and one offering a changing room and bathroom for convenience. Athletic enthusiasts will appreciate the oversized T-shaped sports court equipped for tennis, basketball, and pickleball. The property further includes a three-car heated garage with storage systems and Garage-Tech flooring, a gas generator, Sonos sound system with built-in speakers, a security system, and an unfinished walk-up attic with over 2,000 square feet of potential expansion space. Estate homes of this magnitude and craftsmanship are exceedingly rare and virtually impossible to replicate at this scale. This is more than a residence—it is a private retreat, a statement of achievement, and a once-in-a-lifetime offering in ultra-luxury living.
