    You can’t duplicate this home—plus seller financing! Imagine arriving home to a rare estate where 43,000 protected Hill Country acres stretch endlessly before you, yet you’re minutes from city life. Tucked in gated, amenity-rich Belvedere, this masterpiece delivers serenity without sacrifice—15 min to the Galleria, 35 to DT Austin, 40 to the airport. Recreating it today would cost well over $5M—without the vision, artistry, or years invested in every detail. This is your moment to claim an Architectural Digest-worthy compound of scale, soul, and brilliance. Designed and built by the owner-architect with zero compromise, it sits on 2 manicured, fully fenced acres backing to forever views. A French Tudor work of art, it fuses maximalist interiors with world-class craftsmanship: double island kitchen w/ 3-inch mitered Quartz, European frameless cabinetry, a new Thermador & Bosch suite (48” range, 3 ovens, 2 refrigerators, wine fridge, 2 dishwashers, espresso machine), solid brass hardware, solid-core doors, free-form staircase w/ brass spindles, South African chandeliers. Spaces are made for living boldly—6-car garages, pool lounge/gym or 2nd office, library, game room, craft room, massive home theater, prep pantry, oversized utility, extra W/D in primary linen, future elevator access. Outdoors, it’s your private resort: 12-person spa, oversized pool w/ water arcs, LED & fire features, sport court, turf field, covered dining & lounges. Belvedere offers miles of trails, a private amenity center, fishing pond, and nearby Hamilton Pool. Buyers are circling—when it’s gone, it’s gone.
