EXPERIENCE 6309 NORTHGROVE

A Home in Harmony with the Hill Country

Watch the cinematic tour to experience the natural beauty, architecture, and privacy that define this one-of-a-kind residence.

Overview

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.

The Story of 6309 Northgrove

Truly memorable homes are rarely defined by size alone. What sets them apart is authorship, intention, and the feeling that they could not be easily recreated. 6309 Northgrove offers exactly that.

This is not simply a home that belonged to an architect. It is a home tied to the life and work of Chuck Croslin, a lifelong Austinite whose career, creativity, and design leadership have left a lasting mark on Texas and beyond. Chuck Croslin has been a registered architect since 1979, with a career spanning nearly five decades. Over that time, his work has been nationally published, recognized with numerous state awards, and trusted by an extraordinary range of clients. His firm was consistently ranked among Austin’s top architecture firms by number of registered architects, and his 25th business anniversary was recognized by the Austin Business Journal. His body of work reflects a level of accomplishment and credibility that very few can claim.

Throughout his career, Chuck designed for institutions including the University of Texas, Texas A&M, the National Park Service, and a wide range of public and private clients. His work extended across higher education, hospitality, civic, recreational, and residential projects, reflecting both breadth of experience and a refined understanding of how thoughtful design shapes the way people live.

That legacy is what gives 6309 Northgrove its uncommon significance.

Homes influenced by a career like this carry a different level of intention. They reflect a deeper understanding of proportion, livability, flow, light, and restraint. There is an architectural clarity to a home like this that goes beyond finishes alone. It is felt in the experience of the space itself.

What makes this story even more meaningful is Chuck’s connection to Austin. He was born and raised here, making him part of a rare generation with a lifelong relationship to the city. Long before Austin became what it is today, he was hiking and camping in this very area as an Eagle Scout and member of the Order of the Arrow. His roots here are not recent. They are personal, enduring, and deeply woven into the landscape.

His influence also extends well beyond architecture. Chuck was a founder of the Austin Rodeo and designed its first facility. He served on the boards of Ballet Austin and Capital Metro, completed Leadership Austin, and contributed to civic life in meaningful ways throughout the years. He is listed in Who’s Who in Architecture, yet those who know him best would likely say recognition was never the point. He is not someone who speaks loudly about himself. His work has always spoken for him.

For the next owner, 6309 Northgrove represents more than the purchase of a home. It is an opportunity to own a property with design pedigree, local legacy, and a story that adds real depth to the living experience. In a market where many high end homes can feel interchangeable, this one offers something far more lasting.

6309 Northgrove is not simply a beautiful residence. It is a home with architectural provenance, enduring character, and a legacy that cannot be replicated.
