A once-in-a-generation offering in Marlboro's prestigious Triangle Estates, this extraordinary full-brick custom contemporary ranch stands as a true architectural masterpiece. Privately positioned as the final home on a quiet cul-de-sac, this estate was built with an uncompromising appreciation for luxury, design, and enduring craftsmanship. Offering over 4,900 sq ft not including the full finished walk-out basement, this 6-bedroom, 5.5-bath residence delivers a scale and presence rarely seen. A semi-circular driveway introduces the home's commanding exterior, complete with full brick construction on all sides, a concrete block foundation, and an exceptional 4-car-wide, double-depth garage with parking for up to 8 vehicles. Inside, dramatic cathedral ceilings, custom windows, and abundant natural light create an atmosphere of elegance and grandeur. The sunken family room soars with 23-ft ceilings, while the dining room impresses with 19-ft cathedral ceilings. The private primary wing is a retreat of its own, featuring vaulted ceilings, serene views of the resort-style backyard, an expansive bath with jacuzzi tub, separate shower room, dual vanities, large walk-in closet, and private study. A separate living wing offers 4 bedrooms and 2 baths, along with dedicated butler's quarters. Outdoors, the property transforms into a private resort with a heated gunite pool, expansive gazebo, and beautifully designed paver walkways and borders. Complete with generator support for essential systems and moments from shopping, Route 520, Route 18, and Route 9, this is a landmark Marlboro estate for the buyer seeking something truly irreplaceable.
