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.
