OK, it's white stucco with black frame windows! I like the shape and the fun whimsical cottage look. lots of light inside. Could use native materials to give a more hill country aesthetic without it becoming too kuntry kitchen.
Reminds me of the house/cabin we stayed in in North Carolina overlooked the wine cellar. House with roof terrace and underground kitchen (Thatcher's old house, redeveloped in Chester Square, Belgravia)
