Brand-new, never-lived-in custom residence by award-winning Younger Homes, thoughtfully designed to blend modern Hill Country architecture with low-maintenance, healthy, energy-efficient living. Situated on just over one acre and backing a greenbelt in the desirable Northlake Hills community, the property also features an oversized 2-car garage with additional space for storage, hobbies, or outdoor gear. The highly desirable Reed Park Road location offers convenient access to FM 1431, making commutes to Austin a breeze.
Inside, the open-concept living, kitchen, and dining spaces are filled with natural light and anchored by soaring double-height ceilings with clerestory windows and an impressive 16-foot sliding glass wall that seamlessly connects indoor and outdoor living with room for a future pool. Designer finishes are featured throughout, including exposed ceiling beams in the kitchen, a gas cooktop, and an oversized walk-in pantry with abundant storage.
Designed for flexibility, the spacious third bedroom was intentionally planned to function as either a private bedroom, media room, home office, or bonus living space. For buyers desiring a more traditional bedroom layout, a privacy door can be added with ease.
Built to Energy Star certification standards with a HERS Rating of 56 and constructed to EPA Indoor airPLUS standards, the home delivers exceptional comfort, energy efficiency, and indoor air quality. Unlike many resale homes, this residence was designed and built with a focus on energy efficiency, durability, and healthier indoor living, helping provide lower operating costs, improved comfort, and cleaner indoor air for years to come.
The private rear patio overlooks a tranquil greenbelt setting, while the second story captures glimpses of Lake Travis. Located within the Northlake Hills POA, the neighborhood maintains elevated architectural standards that help protect long-term value and community character.
