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. 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. 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 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. Ideally located on one of the most desirable streets in coveted Newlands, just minutes to downtown Boulder, open space, trails, shops, and schools. Explore the 3D tour and property video.
