This rare offering in Rob Roy on the Lake spans over 7,500 square feet across two thoughtfully designed structures, creating a true multi-generational estate with limitless flexibility. Built to adapt to evolving lifestyles, the property can offer three independent living quarters while maintaining a unified sense of luxury. The 5,800-square-foot main residence features elegant formal living and dining rooms, a chef’s kitchen with breakfast room overlooking a serene courtyard, and a grand family room that flows effortlessly to the backyard retreat. A negative-edge pool, multiple covered terraces, and panoramic Hill Country views set the stage for unforgettable entertaining and fun. The owner’s suite and dedicated office are located on the main level, while the upstairs level can function as its own private four bedroom retreat, with three full bathrooms, a large kitchen, dining and living space as well as a beautiful covered terrace to take in the hill country views. The 2025-built single-story guest house offers 3 bedrooms, 2.5 baths, a 2-car garage, and sleek contemporary interiors all in 1700 sq ft. With expansion potential beneath the structure, this space is equally suited for extended family, guests, or long-term rental income. Together, these homes create an estate that is as versatile as it is beautiful. Whether designed for large families, multi-generational living, or investment potential, the property offers unmatched possibilities. Situated in the prestigious Eanes ISD and feeding to Forest Trail Elementary, West Ridge Middle, and Westlake High School, this estate also boasts an incredibly low 1.6% tax rate and just a $1,000 annual HOA fee—making it one of Westlake’s best-kept secrets.
