Listing timeline with current price, original ask, and market time.
Perched on approximately 4.5 private acres atop a high bluff with 400 feet of waterfront on the Pedernales River arm of Lake Travis, this award-winning custom home is a rare expression of architecture, landscape, and sustainability. Designed in 1998 by Kevin Alter and David Heymann, the residence received the AIA Austin Honor Award and was featured in Texas Architect magazine.
The home is organized into north and south wings connected by a dramatic 96-foot covered deck facing west—ideal for cool morning breakfasts, Hill Country sunsets, and near-constant breezes. Floor-to-ceiling windows, clerestory ventilation, fully insulated 6” exterior walls, and ceiling fans throughout support a thoughtfully engineered, energy-efficient design that encourages natural cross-ventilation and minimal HVAC use.
The north wing offers an open living, dining, and kitchen space with granite counters, custom cabinetry, limestone fireplace, and expansive glazing for abundant natural light. The primary suite features granite finishes and a large walk-in shower. The south wing includes three bedrooms, a full bath, laundry, and a two-car garage, separated by a breezeway that channels prevailing southerly winds.
Notable upgrades include solar panels (2020), rainwater collection providing the sole water source since 2010, two new Trane HVAC systems (2024), updated septic pump, and a private dock with boat slip. Cat5 ethernet outlets throughout support modern connectivity and home automation.
This is a distinctive, architecturally significant waterfront retreat offering privacy, sustainability, and timeless design—ready for its next steward.
