This modernist retreat, rebuilt from the studs in 2019, is privately tucked along a quiet lane just a mile from top-rated Sleepy Hollow School. Designed for architectural distinction and a seamless connection to nature, the home captures sweeping views of Briones and the surrounding hills. Mature trees and manicured gardens frame a grassy play area, creating an idyllic outdoor setting. Inside, the open-concept kitchen and dining area sit beneath elevated ceilings. The chef’s kitchen features premium appliances, a nearly 80-square-foot waterfall island with bar seating for five, and a dining space that easily seats ten to twelve. A glass-enclosed wine cellar showcases up to 180 bottles. Expansive sliders open to a heated deck, ideal for year-round entertaining. The living room centers around a sleek fireplace and oversized windows, while a nearby office offers flexibility for work, nursery, or guest use. The primary suite includes two private decks and a spa-inspired bath with Porcelanosa tile, marble floors, dual vanities, and panoramic views. Upstairs are two additional bedroom suites and a dedicated media room—perfect for movie nights and gatherings. A fourth private suite with exterior entry on the lower level provides an ideal retreat for guests, in-laws, or an au pair.
