5 bed, 4 bath, 6,750 sqft on 330.40 acres in Round Mountain. Round Mountain, TX 78663. $12,900,000. Johnson City ISD.
Luxury Hill Country ranch with a 6,750 sq. ft. main home showcasing chef-caliber Sub-Zero, Miele, and Wolf appliances, 2 laundry rooms, a wine room, 2 primary suites, and views, views, and more views. Includes a guest house, resort-style pool, expansive outdoor entertaining area, and a barn with 4 stalls. One-third improved pasture and two-thirds native landscape with mature oaks, 3 ponds, wet-weather creeks, and abundant wildlife create prime hunting and ranching opportunities. Ideally located just 20 minutes to Horseshoe Bay Jet Center, 60 minutes to Austin, and 90 to San Antonio.
The private drive winds through a wrought-iron gate and climbs across 330 acres of sculpted Hill Country terrain at 4529 Ranch Road 3347 in Round Mountain, where manicured pasture transitions seamlessly into native oak woodland and limestone formations. The 6,750-square-foot residence sits commanding views across carefully managed acreage that balances active ranching with the preservation of natural landscape-one-third productive pasture, two-thirds preserved native ecosystem with mature oak specimens, three spring-fed ponds, and seasonal creek flow that draws native wildlife year-round.
The approach reveals a property designed for serious land stewardship and entertaining. The main residence, completed in 2017, anchors the estate with commercial-grade culinary infrastructure: Sub-Zero and Miele refrigeration, Wolf range and ovens, dual laundry facilities, and a dedicated wine room for serious collectors. Five bedrooms with two primary suites provide guest capacity without compromise. A separate guest house extends hospitality options while maintaining privacy.
The grounds function as an extension of the home. A resort-style pool and expansive stone entertaining terraces open to panoramic Hill Country views. Mature oaks provide natural shade corridors. A four-stall barn with proper pasture fencing establishes working ranch capability-these are functional acres for horse boarding, breeding operations, or livestock management, not decorative backdrop.
The location operates on a dual timeline. The property sits 20 minutes from Horseshoe Bay Jet Center, positioning owners for regional and national travel without the airport commute burden. Austin's downtown core and major employment centers reach within 60 minutes via Highway 71 and US-183. San Antonio's medical, cultural, and business districts sit 90 minutes south. Blanco County's rural character and property tax structure create significant financial advantages over comparable acreage within Travis or Williamson County limits.
The combination of working ranch infrastructure, guest amenities, and unobstructed sightlines across 330 acres positions this property for owners seeking legitimate Hill Country ranching operations alongside luxury entertaining-not a lifestyle property wearing ranch aesthetics, but genuine land management with the residence as its anchor point.
