A once-in-a-generation opportunity in original Rob Roy, one of Westlake’s most prestigious gated enclaves within Eanes ISD.
Spanning an extraordinary 8.5 acres, far exceeding the community’s typical 1 to 1.5-acre homesites, this hilltop estate commands sweeping 340-degree panoramic views across the rolling hills of Westlake and Lake Austin creating a setting that feels both expansive and intensely private.
The 5,223ft home is thoughtfully arranged across three levels, with spectacular views from nearly every room. Entertaining is effortless both indoors and out, with multiple living spaces oriented to capture vistas on every side of the home. Feel on top of the world from the large covered patio off the living room.
The home also features an oversized three-car garage with a work area, along with a large motor court and circular drive that welcome visitors to the front of the home, where some of the most breathtaking views are revealed.
While a substantial home currently exists on the property, the scale, elevation and view corridors present a compelling opportunity for a legacy new construction estate. The buildable area extends well beyond the footprint of the existing residence and driveway, allowing exceptional flexibility to position a future home for maximum views, orientation, privacy and lifestyle. This is a site that invites architectural significance.
To inspire what is possible, conceptual designs have been envisioned by some of Austin’s most respected architectural minds, including Steve Zagorski, Paul Clayton and Brian Korte of Clayton Korte. Their ideas, featured in the listing photography, offer a glimpse into the caliber of estate this extraordinary setting deserves.
Residents of original Rob Roy enjoy 24-hour guarded gate access and a super low 1.46% tax rate. This remarkable property is just 15 minutes from downtown Austin and 20 minutes from ABIA, yet feels worlds away in privacy and scale. Living photo virtually staged.
