Offered fully furnished, this home is truly turnkey. In today’s market, it would cost well over $5M just to replicate the land and construction—without the vision, artistry, or time that shaped this estate. This is a rare opportunity to own a luxury compound with scale, serenity, and architectural soul. An architectural tour de force in gated Belvedere, this is a one-of-a-kind estate imagined, built, and curated by the owner-architect with no compromise in design, quality, or detail. Set on 2 manicured, fully fenced acres backing to protected 43,000 Hill Country acres, this French Tudor masterpiece blends maximalist interiors with world-class craftsmanship and a layout made for elevated living. Every finish tells a story—a double island kitchen with 3-inch mitered Quartz countertops, custom European frameless cabinetry, Thermador appliances, solid brass hardware& fixtures, solid-core doors, free form staircase w/ brass spindles, and hand-crafted chandeliers from South Africa. Artfully designed living spaces include 6 car garages, 5 bedrooms, 8 total baths, a pool lounge that currently serves as a 2nd home office, library, game room, craft room, theater, additional washer/dryer connections in the primary linen closet, & fully engineered, future elevator access. Outside, it’s your own private resort: a glowing 12 person spa, oversized pool with water arcs,LED lighting & fire feature, full-size sport court, turf field, & multiple covered lounge and dining areas. All surrounded by native landscape, big Texas skies, and protected greenbelt views—thanks to over 43,000 AC of adjacent preserved land. Located in the heart of Austin’s Hill Country, Belvedere offers miles of scenic walking trails, a private amenity center, fishing pond, and close access to natural treasures like Hamilton Pool and Reimer’s Ranch. Enjoy serenity with convenience—just 15 minutes to the Galleria, 35 to downtown Austin, and 40 to the airport. Live boldly. Live beautifully. Live Flagler.
