About This Home

THE VISTA ON MT. BONNELL Epic Views | Downtown, Lake Austin to Pennybacker Bridge, Mt. Bonnell, & the Hills. Some properties are defined by their address. This one is defined by its horizon. Perched on one of the highest points in Austin, The Vista commands a view unmatched in the city — the downtown skyline to the east, close enough to feel within reach, and the full sweep of Lake Austin to the west, from Tom Miller Dam to Pennybacker Bridge. Sunset belongs to this house. That kind of position isn't created twice — it's inherited. This is a legacy property, waiting for its next chapter. A CANVAS The existing residence is grand in scale and rich with character — bespoke arches, wrought iron chandeliers from Oaxaca, parquet floors, a chef's kitchen anchored by a round ink granite island. Ten-foot ceilings and floor-to-ceiling windows frame the view from nearly every room, and two wraparound terraces — over 1,500 square feet combined — let you live outdoors with downtown and the lake as your backdrop. Noteworthy: every bedroom offers an ensuite bath, there's a dedicated office w/ views, a double walk-in cedar closet w/ safe, walk-in pantry and heated bathroom flooring in the primary bringing comfort. But the real value here isn't what's built. It's what comes next. Reimagine the layout, modernize the finishes, and make this legacy home your own — or start from the ground up and design a residence built to capture this view from every angle. Inspiration renderings envision one path, reimagined to match the setting. THE SETTING Just under an acre of gated, private grounds on a cul-de-sac, shaded by majestic oaks and mountain laurels — secluded, yet minutes from downtown. This kind of privacy so close to the city center is rare, and land like this doesn't come along twice. Simply put: The Vista on Mt. Bonnell is a rare offering with a view money can't manufacture — and a home ready to be reimagined, renovated, or rebuilt to match it.
