Striking modern architecture features walls of glass, soaring ceilings, skylights, and white oak floors throughout. The dramatic great room opens to covered and open terraces and a level lawn just off the living room patio, with rear grounds anchored by a heritage oak. The designer kitchen showcases Calacatta marble surfaces, a waterfall island, and high-end appliances. The main residence includes a dedicated office, four bedrooms, and three and a half baths, highlighted by a serene primary suite with Windy Hill views and a Zen-inspired bath with private garden. A privately located bedroom suite is ideal for guests or an au pair.
