Property Description

Privately positioned on 0.57 acres behind a dramatic, illuminated gated driveway, this architecturally distinguished estate, renovated by Harvey Hine, reflects a refined mid-century modern aesthetic and offers a sophisticated balance of timeless design, privacy, and effortless livability. An oversized pivoting wood door provides an elegant introduction to the home. The living room features a vaulted ceiling, a statement tiled fireplace, and maple hardwood floors, while large windows and glass doors create a natural connection to the elevated rear deck, ideal for entertaining or quiet evenings at home. The chef’s kitchen blends mid-century-inspired warmth with modern performance, featuring custom walnut cabinetry, a dramatic waterfall stone island, designer tile backsplash, walk-in pantry, Wolf range, and Sub-Zero refrigeration. A refined library lounge transitions to a flexible office or fifth bedroom with direct access to the front patio. The main-floor primary suite offers a serene retreat with a generous walk-in closet and spa-inspired bath, allowing for luxurious single-level living. The fully finished lower level includes a media lounge and private guest suite, with architectural renderings available to reimagine the space as a wellness retreat. Outdoors, the grounds unfold as a secluded oasis with towering 50-foot evergreens, natural boulders, a stone patio, a seasonal water feature, and multiple intimate seating areas. A heated bonus studio provides exceptional flexibility as a gym, art studio, or private office. With its scale, privacy, and layout, the property also presents compelling Sundance Film Festival 2027 rental potential.
