About This Home
BELLAGIO FALLS ON LAKE AUSTIN
Bellagio Falls is a preserve-backed Lake Austin estate spanning over six acres with approximately 600 feet of waterfront. Completed in 2018, the nearly 10,000-square-foot residence offers six bedrooms and 6.5 bathrooms, blending Texas ranch character with refined Santa Barbara architectural influence.
A defining feature of the property is the series of cascading waterfalls integrated into the landscape, creating a natural soundscape and visual focal point that frames long lake views. Combined with its extensive frontage, the estate provides meaningful separation and privacy rarely found on Lake Austin.
The residence includes expansive living areas, inlaid Texas mesquite flooring, a media room, billiards room, and a game room with an official-size shuffleboard. A newly constructed resort-style pool and two-story boat dock extend the estate to the water. A four-car garage, private orchard, and ample room for future additions such as a casita or sport court provide flexibility without compromising scale.
The property is surrounded by greenbelt secured through recorded deed restrictions filed with the county, ensuring long-term protection from future development. Across the water lies the Balcones Canyonlands Preserve, federally recognized conservation habitat managed by the City of Austin. The result is open shoreline, reduced congestion, and enduring privacy.
Mature oak trees, a century-old heritage pecan, bald cypress, sycamore, mulberry, and fruit trees anchor the grounds, reinforcing the estate’s established and intentional landscape.
Bellagio Falls represents a rare combination of scale, protected surroundings, and architectural presence in one of Lake Austin’s most desirable stretches.
The 9,725-square-foot residence at 15016 Flat Top Ranch Road in Steiner Ranch commands approximately 600 feet of Lake Austin waterfront with 5.94 acres of preserve-backed land, creating a private resort environment within the 78732 zip code of northwest Austin. Completed in 2018, this six-bedroom, 6.5-bath home merges Texas ranch authenticity with refined Santa Barbara-influenced architecture-a design philosophy that extends seamlessly from interior to waterfront.
The defining architectural feature is a series of cascading waterfalls integrated directly into the landscape, generating natural water sounds and visual depth that frame unobstructed lake views across Balcones Canyonlands Preserve, the federally managed conservation habitat on the opposite shoreline. This preserved greenbelt, secured through recorded deed restrictions filed with Travis County, eliminates the development pressure that typically constrains Lake Austin properties and ensures the open water views will remain permanent.
Interior spaces flow through inlaid Texas mesquite flooring across expansive living areas, with dedicated leisure rooms including a media room, billiards room, and game room featuring an official-size shuffleboard court. The newly constructed resort-style pool and spa anchor the outdoor entertainment zones, while a two-story boat dock accommodates watercraft and extends usable waterfront space directly from the home. A four-car garage and private orchard occupy the northern portions of the property, with flexibility for future additions-a casita or sport court-without compromising the estate's established scale.
The landscape is anchored by mature native oaks, a century-old heritage pecan, bald cypress, sycamore, mulberry, and productive fruit trees. These established plantings provide both privacy screening and the visual weight that distinguishes properties developed with long-term intention rather than recent construction. The combination of this vegetation buffer and the recorded deed restrictions protecting surrounding greenbelt creates meaningful separation rarely available on Lake Austin's developed shoreline.
At $20 million ($2,057 per square foot), the property sits within the Austin luxury market's refined tier, reflecting both the waterfront acreage and the architectural execution. The 155 days on market reflects the selective buyer pool for estates of this scale and price within the Austin market. Living here means permanent vacation amenities-the pool, spa, boat dock, and lake access-without leaving the Travis County tax jurisdiction, positioning ownership as both lifestyle acquisition and geographic stability in one of Austin's most protected waterfront communities.

Lake Austin is Austin's most exclusive waterfront corridor - 22 miles of constant-level shoreline in 78732, 15 minutes from downtown. Waterfront homes start around $4M and trophy lots with 200+ feet of flat shoreline trade at $15M-$35M+. The lake is controlled by Tom Miller Dam, which maintains consistent water levels year-round - the key advantage over seasonal Lake Travis.
This is one of Austin's thinnest markets. Roughly 22 miles of total shoreline, and at any given time only 3-5 homes are actively listed. Many of the best lots trade privately through agent relationships before they ever reach the MLS. The finite supply creates a structural price floor that insulates Lake Austin from broader market cycles.
Buyers here want water access as daily life, not a weekend plan. Morning paddleboard, afternoon ski run, burgers at Ski Shores by boat, sunset from your own dock watching Hill Country ridgelines. The practical side matters too: you are inside Austin city limits with full services, 15 minutes from downtown, 10 from the Domain.
Four Seasons Private Residences is under development on 145 acres with 188 planned homes - the first significant new inventory since the lake was established. Eanes ISD and Leander ISD serve different sections of the corridor, both with strong school ratings.
