403 Brookhaven Trl, Austin, TX 78746

In Austin’s Westwood neighborhood, this single-story residence sits on a landscaped 0.43-acre corner lot and reflects a comprehensive architect-led transformation by Alterstudio Architecture. Originally built in 1970, the home was taken down to the studs in 2016 and reimagined to improve structure, light, and livability, introducing vaulted ceilings, expansive windows, and a more open interior layout across approximately 2,804 square feet (per FPG).

The three-bedroom, three-bath floor plan centers on bright living spaces with wood flooring and a custom indoor fireplace. A reconfigured layout created a larger primary suite and an expanded, sound-isolated media room, while custom Crystal Cabinetry, updated appliances, and new plumbing and electrical systems were installed throughout the renovation.

Additional improvements included new windows and doors, insulation upgrades with spray foam, integrated Control4 smart home and security, and built-out attic storage above the garage.

Outdoor spaces were designed for both function and scale. The backyard features a pool and spa added in 2018, surrounded by substantial hardscape, lawn areas, and mature trees, with utility connections already extended for a potential future cabana. More recent capital improvements include a standing-seam metal roof, updated cedar siding and eaves, refreshed front and side yard landscaping and hardscape, a new HVAC unit serving the bedroom wing, and a Speed Queen washer and dryer.

A carefully modernized Westwood property combining architectural clarity, thoughtful systems upgrades, and a generously sized lot.

Benefits from a low 1.45% tax rate because property is located in the West Lake Hills ETJ.

An Alterstudio-led, down-to-the-studs renovation on a 0.4336-acre corner lot is what sets 403 Brookhaven Trl apart, especially at $794 per square foot in Westlake Hills. At 403 Brookhaven Trl in Austin 78746, you are getting a single-story residential single-family residence with 2,804 square feet, 3 bedrooms, 3 baths, a pool, and a rare mix of architectural discipline and everyday function inside Eanes ISD.

Originally built in 1970, the house was reworked in 2016 with the upgrades buyers usually hope for but rarely find already done: new plumbing, updated electrical, new windows and doors, spray-foam insulation, Control4 smart home integration, and a layout that opens the main living spaces while still giving the bedroom wing privacy. Vaulted ceilings and larger expanses of glass change the feel of the interior in a real way. Light moves through the house differently, and the living areas read larger than the square footage suggests. The primary suite was enlarged, the media room was sound-isolated, and the kitchen received Crystal Cabinetry and updated appliances. A standing-seam metal roof and newer HVAC work help keep the near-term maintenance list short. The fireplace adds a grounded focal point to the main living area, and the 2-car garage includes useful attic storage above.

The lot is one of the strongest parts of the value story. At 0.4336 acres, there is real breathing room around the home, and the backyard was designed to use it well. The pool and spa, added in 2018, sit within substantial hardscape, lawn, and mature trees, with utility connections already in place for a future cabana. For buyers comparing Westlake options around this price point, outdoor usability matters as much as interior finish, and this property covers both.

Location is where 403 Brookhaven Trl gets even sharper. Westlake Hills sits just off Bee Caves Road with fast access to MoPac and Loop 360, which usually puts downtown Austin, Zilker Park, Barton Springs, and Barton Creek Square within about 10 to 15 minutes depending on traffic. School alignment is a major draw here: Eanes ISD, with Eanes Elementary, Hill Country Middle School, and Westlake High School. In Travis County, that combination continues to anchor demand, especially for buyers who want Westlake access without giving up lot size or a usable one-story floor plan. With only 7 days on market and a reported 1.45 percent tax rate in the West Lake Hills ETJ, this is the kind of Austin property that fits how people want to live now and should continue to hold value well over time.

Westlake Hills is an incorporated city in Austin's 78746 ZIP code, five minutes west of downtown via Bee Caves Road. Eanes ISD - ranked #1 in Texas by Niche 2026 - draws most buyers. Median home price $2.4M, with estates from $1.2M updates to $10M+ hilltop compounds.

Roughly 1,000 total homes sit on wooded lots averaging half an acre to two acres, spread across the hills south of the Colorado River. Lost Creek, Davenport Ranch, The Oaks, and Bee Caves Woods each have a different character - from 1970s ranches on established lots to new-build Hill Country Contemporary estates with 20-foot ceilings and limestone facades.

The housing stock is in a generational transition. Original 1970s-80s ranch homes sell as teardowns at $1-2M for land alone, replaced by $3-8M contemporary builds. At any given time, 25-30 homes are actively listed. Inventory is tight, and a meaningful share of deals happen off-market through agent networks.

What defines daily life here: morning coffee at Swedish Hill, school drop-off at Eanes Elementary or Bridge Point, a trail run at Wild Basin Preserve, and dinner at Sway or Las Palomas without crossing MoPac. This is a quiet neighborhood built around schools and outdoor access, not nightlife or walkable retail. The people who live here chose it for exactly that trade-off.
