Perched atop one of the most iconic elevations in Central Austin, The Ridge at Mount Bonnell presents a rare opportunity to craft a world-class estate on nearly six acres of private, blufftop land. With panoramic views over Lake Austin and a front-row seat to the Pennybacker Bridge, this one-of-a-kind homesite offers a setting that’s as awe-inspiring as it is exclusive.
Located within minutes of Austin’s best shopping, dining, and entertainment—yet wrapped in natural serenity—4323 Mount Bonnell Road invites you to build a home that is both a personal retreat and a bold architectural statement. Included in the offering are conceptual plans by globally acclaimed architect Tom Kundig, whose work is celebrated for its seamless integration with the land. His vision here imagines a sculptural modern residence that disappears into the cliffside while maximizing light, privacy, and views.
This is more than a homesite—it’s a legacy property in one of Austin’s most historically significant and sought-after locations. Whether you realize the Kundig vision or bring your own design team, the result will be something truly singular: a custom home at the apex of Austin, surrounded by nature, overlooking the water, and unlike anything else on the market.
There are many beautiful spots in Austin. There is only one Mount Bonnell.
