Set within the scenic hills of Diamond Ridge, you’ll find architectural design with refined luxury and craftsmanship. Expansive windows and living spaces create openness while framing the surrounding landscape. Within the kitchen, a limestone hood, imported from Canada, anchors the space above stone countertops, while more than 5,000 pounds of granite are incorporated throughout the home’s surfaces. Heated floors add comfort, and two paneled drawer refrigerators are built into the oversized island.
Indoor and outdoor living blend effortlessly. The upper deck, accessible from the kitchen, great room, and primary suite, captures panoramic views and features a built-in grill, custom cabinetry, and overhead fans. Below, the walk-out lower level opens through large glass doors to a second deck. A spacious bar and kitchenette include a sink, dishwasher, microwave, ice cabinet, and two illuminated mini refrigerators. The level also features guest bedrooms, including one with a jetted tub and one with a private bath, along with a fitness studio with direct access to the putting green and front yard.
The primary suite offers an architectural sloped ceiling design and a stone fireplace. Its spa inspired bath features heated floors, a circular walk-in shower, and a freestanding soaking tub beneath a crystal chandelier. The main level also features an executive office with classic wainscoting and custom built in library with a rolling ladder. Surround sound speakers in the kitchen, dining room, office, throughout basement, and primary suite. An automated LED lighting system activates at sunset, illuminating the property’s front and backyard.
Additional highlights include a laundry room with custom cabinetry, an elevator shaft built for future installation, and a four-car garage with custom shelving and dual interior entry points leading to both the basement and laundry area.
