The main living spaces frame a ~9-mile Hill Country view over Balcones Canyonlands Preserve. Four bedrooms create real flexibility for work-from-home life and guests. Set on 0.42 acres outside city limits, the property offers no city taxes, and no active HOA. Three view-facing outdoor spaces anchor everyday living: an expansive main-level deck and upper balcony, rebuilt in 2025, plus a screened porch. Large windows frame the preserve view and fill the main living areas with natural light. The open kitchen, dining, and living area opens to the deck. The fenced yard offers a versatile space for dogs, play, and gardening, while mature trees add privacy from neighboring homes. Positioned at the back of a neighborhood in Lake Travis ISD, the home feels like a retreat yet is near conveniences, including Whole Foods. Outside, the home features natural limestone cladding and metal roofing. Inside, solid oak plank flooring has been refinished and extended into additional bedrooms (2022). Main living areas feature a durable concrete floor that is easy to maintain. The native, drought-tolerant landscaping helps keep maintenance low. Key updates include a septic tank rebuild (2022) and a commercial-grade water heater (2019). In 2025, improvements included a new deck and balcony, along with refreshed paint and lighting and updated switches and outlets throughout. An expansive driveway comfortably accommodates daily parking and guests. Generous closets keep daily life organized. For seasonal and long-term items, attic storage with pull-down ladder access keeps living areas clear. Per survey, the lot offers potential for a future garage or addition, subject to setbacks, easements, and applicable approvals. Homes backed by preserved land, with four-bedroom flexibility and outdoor spaces built for daily use, are often held for decades—this one was, until now.
