23705 Old Ferry Rd Unit #15, Spicewood, TX 78669

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.

A 4.5518-acre blufftop waterfront setting with about 400 feet on the Pedernales River arm of Lake Travis is the fact that defines 23705 Old Ferry Rd Unit #15. In Spicewood in Spicewood, this is not simply a 2,837 square foot single-family home priced at $1.45M, or $511 per square foot. It is a land-driven offering where shoreline, elevation, privacy, and architectural pedigree all matter at once. Built in 1998 and on the market for just 5 days, the property combines a four bedroom, two bath, one half bath layout with a site that is difficult to replicate in Travis County.

The house itself carries unusual credibility. Designed by Kevin Alter and David Heymann, it received an AIA Austin Honor Award and was featured in Texas Architect, which places it in a different category than typical waterfront inventory. The plan is split into north and south wings connected by a 96-foot covered deck facing west, a layout that takes full advantage of light, breeze, and the blufftop position. Floor-to-ceiling glass, clerestory ventilation, insulated 6-inch exterior walls, and ceiling fans throughout reflect a house engineered for cross-ventilation and reduced HVAC dependence rather than one that relies only on mechanical systems. The main living, dining, and kitchen areas are open and bright, with granite counters, custom cabinetry, and a limestone fireplace. The primary suite continues that material quality with granite finishes and a large walk-in shower, while the opposite wing holds three additional bedrooms, a full bath, laundry, and the two-car garage.

The infrastructure story is just as relevant as the design. Solar panels were added in 2020. Rainwater collection has served as the sole water source since 2010. Two new Trane HVAC systems were installed in 2024, and the septic pump has been updated. A private dock with boat slip extends the utility of the waterfront, and Cat5 ethernet throughout supports modern connectivity and home automation without compromise. For buyers who understand that long-term value in luxury property comes from scarce land characteristics, enduring architecture, and hard utility upgrades, this property is positioned as a waterfront hold with lasting relevance.
