304 Duffy Ln sits on a greenbelt lot in Rough Hollow, the Lake Travis community in Lakeway. At 4,131 sq ft with 4 bedrooms, 4 baths, a separate casita, and a 3-car garage, this 2014 Grand Haven home gives you a lot of house for the price, and it’s move in ready. The house and casita were freshly painted in October 2026 (walls, ceilings, doors, and trim), along with the front of the home, the garage doors, and every exterior door. The upstairs media room has brand new carpet, and the primary suite is on the main level. The casita sits at the front of the home, separate from the main house, so it works as guest quarters or an office where you can actually close the door on work at the end of the day. Outside, there’s a courtyard with patio space for entertaining. Rough Hollow is the real draw, and a community pool and amenity center are within walking distance. The Yacht Club on Lake Travis has a marina, bar and grill, resort-style pool, paddle boards, and yoga overlooking the lake. Highland Village adds four pools, including a lazy river and an adult pool with a swim-up cabana bar, plus a splash pad, clubhouse, playscape, tennis and basketball courts, soccer fields, sand volleyball, and hike and bike trails that run down to the lake. Zoned to Lake Travis ISD.
