Newly completed, The Onyx is among the most significant residential offerings ever brought to market in Westlake Hills. Defined by rare elevation, sweeping downtown Austin views, and exceptional execution, this architectural estate delivers scale, presence, and privacy at a level few homes achieve. A secure, gated, and privately walled arrival sets the tone for the residence. Spanning approximately 11,000 square feet on nearly an acre, the home was built by Paradisa Homes with an uncompromising focus on proportion, durability, and enduring quality. Walls of glass frame the living environment throughout, including a custom Fleetwood Edge sliding system—the largest of its kind—opening to uninterrupted city and Hill Country views. Interior volumes are striking, with ceilings reaching up to 18 feet and light moving intentionally throughout the day. The kitchen is anchored by a 12-foot Milano marble island with Gaggenau appliances, complemented by a fully equipped catering kitchen with Thermador appliances and a glass-enclosed wine vault with approximately 600-bottle capacity. An entire level is dedicated to the owner’s suite, featuring a private lounge, office, dual walk-in closets, safe room, and a spa-like bath with soaking tub, oversized rain shower, and floor-to-ceiling glass framing downtown views. Additional amenities include a private theater, fitness studio with steam shower, library, full bar opening to the pool, elevator, and a fourth-floor Sky Parlor designed for indoor-outdoor entertaining. Outdoor living includes a resort-style pool and spa, cabana with swim-up bar, outdoor kitchen, pool bath, and expansive lawns. A detached guest house offers a kitchen, living space, and en-suite bedroom. Garage parking accommodates 6–12 vehicles with lift capability. Located in Eanes ISD and minutes from downtown Austin.
