Exterior Concrete Flat Mid-Century Photos

Designed by Arthur Witthoefft of Skidmore, Owings & Merrill in 1961, this five-bedroom, five-bathroom midcentury house is set in the woods of Armonk, New York. The 5,000-square-foot home features full-height walls of glass, a wraparound floating terrace, and a quiet deck that overlooks the site's sylvan surroundings.
