Description

This rare multi-residence estate in Rob Roy on the Lake in Eanes ISD offers a 5-bedroom, 6.5-bath main house plus a single-story 2–3 bedroom, 2.5-bath guest house. Together, the two structures provide more than 7,500 sq ft of flexible living space on 1.58 acres. The 5,859 sq ft main residence features elegant formal spaces, generous living areas, a chef’s kitchen, main-level owner’s suite, office, multiple terraces and a negative-edge pool. Four oversized bedrooms and three full bathrooms lie upstairs along with a spacious game room will full kitchen. The 1,677 sq ft guest house lives independently with its own private driveway, garage, full kitchen, laundry and separate living spaces indoors and out. A beautiful rear terrace overlooks the canyon below, creating a peaceful retreat ideal for extended family, guests, older children, work-from-home needs or potential rental use. This gorgeous estate covers over 1.5 acres and has a super low property tax rate of just 1.6% due to its location in Travis County (not in City of Austin). Properties like this are rare in Westlake and should not be overlooked if you are in need of proper guest house for elders, a work from home solution or a luxurious space for guests when they come to visit, 405 Barrett Lane is your answer! And Eanes schools too!
