A once in a decade opportunity in Northwest Hills, 6309 Northgrove Rd offers 3,752 square feet on an exceptionally rare 5.09 acre estate lot in the heart of Cat Mountain/Northwest Hills. Designed as an award-winning architect's personal home and perched at an elevation of 870 ft, nearly 100 ft higher than Mt Bonnell, the setting delivers sweeping Hill Country panoramas and unforgettable sunsets from nearly 1,600 square feet of porches and balconies. This is a true sanctuary in the city, where mature landscape, long-range views, and the sounds of nature create a sense of privacy that is almost impossible to find in Austin. A private walking trail offers a unique way to experience the natural setting, and after rainfall the property comes alive with a natural waterfall and a creek-like flow across the land. A 1,200 Gallon rainwater collection system supports thoughtful water use for landscaping. The setting is rich with wildlife and a variety of bird species. Tucked at the end of a quiet cul-de-sac with only three homes, the neighborhood feel is equally special, with friendly, active neighbors and seasonal traditions that make the community feel vibrant throughout the year. Recent major improvements include a roof installed in 2024 and HVAC replacements in 2024 and 2025. Select double pane window replacements, and landscaping was redesigned in 2023 with installed Zoysia grass, prized for its dense, luxury carpet-like feel and water conservation friendly performance. According to the City of Austin, the property may allow up to three dwelling units, creating potential for an additional home on the flat portion of the lot closer to the cul-de-sac. Pool potential plans available on request. Near Doss School Park, Shinoak Valley Greenbelt, and the 10-acre Allen Park. Zoned to top schools like Doss Elementary, Murchison Middle, and Anderson High, and located near HEB, CVS, and UPS, with an easy drive to Downtown and dozens of nearby restaurants, including Grove Wine Bar.
