Architect Tim Cuppett designed a new farmhouse accented with imperfectly layered Texas limestone. The purposely rambling plan looks like it was added onto over time. A windowed entry connects two structures in the spirit of a Southern dogtrot, yet the floor-to-ceiling glass gives it an updated feel. "So many of the elements on this house are familiar—white clapboard, metal roof, stacked-stone chimney," says Executive Editor Jessica Thuston. "Yet the windows are the first clue that it has a modern spin."
