Futuro

A Futuro house, or Futuro Pod, is a round, prefabricated house designed by Finnish architect Matti Suuronen, of which fewer than 100 were built during the late 1960s and early 1970s. The shape, reminiscent of a flying saucer, and the structure's airplane hatch entrance has made the houses sought after by collectors. The Futuro is composed of fiberglass-reinforced polyester plastic, polyester-polyurethane, and poly, measuring 4 metres high and 8 metres in diameter.
