Welcome to The Rockcliff Estate—a newly renovated, design-forward private compound where timeless architecture meets modern luxury across 3.3A± acres in the heart of Westlake. Conceived by renowned architect Luis Jauregui, this exceptional estate has been thoughtfully reimagined with sophisticated, contemporary updates, offering a rare balance of Old World craftsmanship and elevated, turnkey living. Comprising two distinct lakefront properties, the estate delivers a highly coveted combination on Lake Austin—private water access set apart from the main residence, allowing for a more secure, secluded living experience without sacrificing the lifestyle of the lake. From the moment you arrive, a sense of quiet prestige unfolds. A dramatic serpentine stone wall and gated entrance—along with a secondary service entry gate for guests, staff, or overflow parking—reveal lush, manicured grounds designed for both privacy and presence. The property spans six combined lots/tracts of land, creating a true estate setting with a flat front yard and gently sloping rear terrain that blends seamlessly into the surrounding Hill Country. The Rockcliff Estate includes the properties at 4646 & 1810 Rockcliff Road. Just beyond, across Rockcliff Road, awaits one of the estate's most extraordinary features—approximately 330A± feet of combined private, deeded Lake Austin shoreline. Mornings begin with paddleboarding at sunrise, afternoons drift into kayaking along the shoreline, and evenings invite effortless boating from your own access point. Enhancing the long-term waterfront potential, the permit process for up to three private boat docks is currently underway. Nature trails wind through the property, where abundant wildlife enhances the sense of tranquility and connection to the land. Inside, the home has been meticulously updated to reflect today's most desirable finishes while honoring its architectural roots. Soaring 26-foot ceilings, expansive walls of glass, and a sweeping spiral staircase create a breathtaking sense of scale. Newly refreshed interiors introduce a lighter, more modern palette, complemented by hand-laid Texas stone, Luders limestone detailing across the driveway and patios, warm travertine, and both traditional longleaf pine and rare “sinker†longleaf pine flooring. The main-level primary suite is a serene retreat, featuring a private sitting area, fireplace, and coffee bar. The spa-caliber bath showcases custom travertine finishes, an oversized walk-in shower, freestanding soaking tub, and an expansive dressing closet with bespoke built-ins—creating a true sanctuary of comfort and sophistication. At the heart of the home, the fully remodeled chef's kitchen has been transformed with modern luxury in mind. Taj Mahal Perla Venata quartzite countertops, designer lighting, an oversized island, and top-tier appliances—including dual 48" SubZero refrigerators, a SubZero wine cabinet, and a Wolf drawer microwave—anchor the space. An expansive butler's pantry with new appliances enhances both functionality and flow, making the home equally suited for grand entertaining or intimate gatherings. The adjoining family room, framed by floor-to-ceiling windows and a statement stone fireplace, offers warmth and connection. Designed for expansive living, the estate includes four additional en-suite bedrooms, a dedicated home gym, and an oversized four-car garage equipped with a 50-amp EV power outlet. Comfort and efficiency are elevated with newly installed Lennox dual-fuel HVAC systems and the option for a separate water treatment enhancement system. Outdoor living is equally impressive. Two sprawling covered patios overlook a resort-style setting complete with a heated pool, spa, stream, and waterfall features. A newly constructed, oversized lighted pickleball court offers recreation day or night, while panoramic views stretch across the Hill Country to the iconic Pennybacker Bridge in the distance.
