Why Koti picked this home
This 11-acre estate features private waterfront access and a spacious layout with 5,275 sqft, 4 beds, and 5 baths.
Set on 11 acres with several hundred feet of waterfront on a quiet lagoon off Lake Austin, this estate offers a rare level of seclusion rarely found in Westlake. A long, winding drive crosses a stone bridge over a gentle creek before arriving at the home, creating the feeling of a hidden retreat completely removed from the city. Designed by Shiflet Group Architects and built by renowned builder David Dalgleish, the home was crafted with a quiet, understated elegance that stands in sharp contrast to the typical “showplace” lake home. The single-story floorplan unfolds naturally with subtle level changes, multiple screened porches, walls of windows, and seamless connections to the surrounding landscape. The home features 4 bedrooms with ensuite baths, formal living and dining spaces, an inviting family room open to the kitchen and breakfast area, a detached 3-car garage, pool, and a brand-new two-story boat dock. A private trail leads directly to Austin Country Club, offering a truly unique lifestyle opportunity. Zoned to highly acclaimed Eanes ISD including Bridge Point Elementary, Hill Country Middle, and Westlake High School. Rarely does a property combine this level of acreage, privacy, waterfront, architecture, and location in the middle of Westlake.
