Two private office spaces, a hidden room behind a bookcase, a separate entrance casita, and a 0.44 acre greenbelt lot. One of the largest homesites in the Las Brisas neighborhood of Rough Hollow. A rare opportunity: the expanded Zilker II offers the same layout as the Westin Homes model with nearly 500 sq ft more, on a floor plan no longer offered in Rough Hollow. Both work from home? Two private office spaces: one traditional office with French doors and built-ins on the main level, and one study loft tucked above the owner's closet. And then there's the room nobody sees coming. Pull the bookcase and step into a hidden flex room: home gym, yoga sanctuary, craft room, it's up to you. Parents visiting for a month or moving in for good? The private entrance casita gives them their own front door, full bath, and dedicated central air. Kids? A large game room, a media room wired for Dolby Atmos, and nearly half an acre of greenbelt backed yard with room for a pool and a sport court. Consider yourself a chef? The chef's kitchen anchors it all with a Thermador, Wolf, and Cove appliance suite, massive granite island, and custom cabinetry. Entertain across two patios: one with a wood burning fireplace, the other with panoramic greenbelt views and a built-in grill area. Owner's suite on main level with casita and three bedrooms up with ensuite bathrooms. $200K+ in builder options and upgrades, plus $60K+ in owner improvements, including a fully customized owner's closet, water softener, and epoxy finished garage with ceiling storage. A walkable 100 yards to Rough Hollow Elementary, with a public park and playground planned beside it for 2027. A quick drive or golf cart ride to the Yacht Club, marina, and lazy river, all in acclaimed Lake Travis ISD. Schedule your private showing today.
