Dramatic yet also comfortable, unique but also classic, this modern house in Armonk, N.Y., was thoughtfully designed by noted architect Roy Johnson, a disciple of Frank Lloyd Wright. The semi-circular open-plan home includes a two-story living room with dramatic beamed ceiling, river rock fireplace, huge windows, and views of nature. The semi-circular Bilotta kitchen also has windows rising two stories, a breakfast room, and access to a large and beautiful screened porch.
