About This Property

Nestled on a hillside in Austin's most exclusive gated neighborhood of Rob Roy, this charming, remodeled estate offers breathtaking panoramic views of the scenic Hill Country, combining exceptional craftsmanship with luxurious living.

The main level boasts over 7,000 square feet of single-level living, with 10.5' vaulted ceilings that soar to 20 feet in the kitchen, common areas, and owner's suite, creating a breathtaking sense of space. The 1,300 sq. ft. owner's suite is a private retreat, complemented by an artisan soaking tub, spacious freestanding shower, and an adjacent gym and office space, with direct access to the deck and pool. The heart of the home is the master chef's kitchen, outfitted with high-end appliances and an oversized dine-in island, perfect for both everyday living and entertaining. Wine enthusiasts will appreciate the dedicated showroom for 600+ bottles nearby.

The property is listed with TCAD square footage at 8,685, but the total finished-out square footage is 9,828, providing ample space for both relaxation and entertainment. Bonus space on the lower level offers flexibility, with a guest suite featuring a private deck and entryway, along with a theater room and multi-purpose craft space.

Outside, the southerly-facing backyard is an entertainer's dream, with Brazilian IPE decking surrounding a resort-style pool with adjacent chef's gazebo, an 1,800 sq. ft. sports court ready for your custom touch, and an outdoor full bath and changing room conveniently situated between the two. Two private courtyards, enclosed by 8' brick walls, offer serene outdoor escapes just off the kitchen and secondary bedrooms.

Conveniently located within minutes of Austin's top private schools, cultural landmarks, and tech hubs, this home also falls within the award-winning Eanes ISD school district. Live luxuriously just a stone's throw from everything Austin has to offer.
