    Perched atop more than three acres in the prestigious gated community of Barton Creek's Mirador Escala, The Prominence of Austin is a private estate offering an extraordinary blend of scale, privacy, and modern refinement. With a rare seven-car garage, secure guest accommodations, and sweeping views of the Hill Country, this grand residence has been completely reimagined to meet the expectations of the most discerning buyer. Located just 15 minutes from downtown Austin and under 20 minutes from the airport, the home is also minutes from Barton Creek Country Club, known for its world-class golf, tennis, and wellness amenities. A gated entrance leads to a long, winding drive that opens to manicured grounds and an architecturally striking façade finished in hand-applied LaHabra stucco—a premium exterior treatment that elevates the home's aesthetic and speaks to the uncompromising quality found throughout. From its commanding position, the property enjoys complete privacy, a serene natural backdrop, and ample space to add a tennis or pickleball court, gardens, or additional structures. The estate underwent a comprehensive transformation between 2018 and 2023, with no detail overlooked. Floor-to-ceiling Venetian plaster, new Presidio steel-framed windows and doors, and bespoke millwork create a timeless interior rooted in craftsmanship. Inside, soaring ceilings and arched openings are complemented by mesquite hardwood floors with inlaid ebony, solid walnut trim, and refined textures throughout. The two-story foyer stuns with a vintage chandelier and curved staircase, setting the tone for a home that is as grand as it is welcoming. The living and dining spaces strike a balance between formal elegance and relaxed everyday living, each framed by walls of glass that open to expansive terraces and capture natural light at every turn. The chef's kitchen is the heart of the home, featuring custom cabinetry, quartz countertops, dual islands, and a full suite of Wolf and Sub-Zero appliances—perfectly suited for entertaining or quiet evenings at home. The owner's wing is a private sanctuary, complete with a sitting room and see-through fireplace, two oversized dressing rooms, a wet bar, and a spa-worthy bathroom wrapped in Calcutta Gold marble. A steam room and fitness studio are also tucked within this wing, offering wellness and comfort in equal measure. A highlight of the home is the secure guest quarters, privately situated with its own entrance and dedicated garage. Complete with a living room, full kitchen, dining area, bedroom, bathroom, and its own laundry, this space offers privacy and flexibility for extended guests or multigenerational living—all while remaining seamlessly integrated into the overall design. Outdoors, the property continues to impress with multiple covered patios, a summer kitchen, a tranquil spa, and a dramatic infinity-edge pool that appears to spill into the greenbelt below. Surrounded by lush landscaping and protected views, the setting is both peaceful and visually stunning. An elegant art gallery hallway leads to a custom wine cellar designed for tastings and entertaining, while a theater and game room with full bar provide even more space for leisure and hosting. With modern systems including Lutron lighting, new HVAC, and upgraded electrical, this estate is as advanced as it is beautiful. Every surface—from the LaHabra stucco exterior to the Venetian plaster interiors—reflects a commitment to enduring quality and timeless design. The Prominence of Austin is more than a home—it's a private sanctuary, a work of architecture, and a rare opportunity to own one of the most refined compounds in one of Austin's most exclusive enclaves.
