Astronaut Alan Shepard's historical landmark home in Lakeway is available to the market! One of the original Mercury 7 astronauts and the first American launched into space in 1961 later commanded the Apollo 14 moon mission in 1971 becoming the only Mercury astronaut to reach the moon. He hand-picked this lot on a rocky promontory 140 feet above Lake Travis on the main basin across from Point Venture. In 1967, Commander Shepard built this 3,339 square foot property which includes an 85-foot back deck with sweeping views of the skies, hill country and lake. All four bedrooms offer ensuite baths located on the main level with a game room, large storage closet and a fifth full bath including a sauna on the lower terrace. Renovations over the years include upgrades to the kitchen and bathrooms in 2010. A pool was added shortly after and the current owners have further upgraded the home with hardwood floors throughout and all new windows. All 8 sliding patio doors were replaced and the A/C ductwork was replaced and rerouted along with a complete insulation package enhancing efficiency. Along with the lake being the main focal point in the living room, a large wood burning stone fireplace offers warmth and comfort. Within the two-car garage is a closed off work room with a built-in storage system. In addition to great shopping, restaurants and golf courses close by, the community benefits from no HOA fees and a low tax rate of 1.7%. 818 Mariner provides a piece of American history while enjoying breath taking starry sky views and Lake Travis.
