Set on a rare 1.2-acre private lot, this custom modern estate delivers the scale, privacy, and architectural precision today's luxury buyer is searching for. The first floor unfolds beneath soaring 12 to 22-foot ceilings, striking a rare balance between open-concept scale and defined living spaces. Marble and premium hardwood flooring run throughout, and a sculptural floating staircase with glass railing anchors the main living area as a genuine architectural centerpiece. Step outside into true resort living. A 60-foot pool and spa are framed by expansive granite decking, complemented by an outdoor shower and restroom for effortless indoor-outdoor living. Two full outdoor kitchens - each equipped with Sub-Zero and Wolf appliances - make this a home built for entertaining at scale, whether it's an intimate dinner or a full-scale event. Mature trees and a tall aluminum-composite fence wrap the grounds in natural seclusion, while 4K security cameras add peace of mind without compromising the resort-like feel. Arrival is just as considered: an automatic-gated front entry opens to a granite-paved driveway leading to a 4-car garage finished with metallic epoxy flooring and an EV charger. Inside, the craftsmanship continues with a chef's kitchen outfitted in Dacor appliances and premium European cabinetry that extends into the bathrooms, laundry, and master closets. The primary bathroom features a built-in sauna, adding a spa-like retreat to the private wing of the home. Frameless interior doors with European magnetic hardware, energy-efficient reflective aluminum windows and doors, modern touch-control lighting, and a striking 6'x9' ceramic pivot entry door bring the same level of detail to every corner of the home. Beyond the home itself, the expansive lot offers rare upside: ample room to add a tennis or pickleball court, basketball court, guest house - or all three.
