Architects Mark Hammer and Don DiRocco have a reverence for a golden age of modern architecture on Cape Cod, Massachusetts. After International Style opened up views and floor plans in the 1920s and ’30s, a group of architects applied those principles in homes at the very tip of Cape Cod, and like-minded artists followed. New modern homes were built in Wellfleet and Truro to interact with nature and float lightly on the land. Many now are part of the National Park Service’s Cape Cod National Seashore, founded by John F. Kennedy in 1961.
