The Futuro House was a prefabricated fibreglass house that looked like a spaceship and was designed in the 1960s. The original idea was that they would be mass-produced and used as chalets or holiday homes - however the rise in the cost of oil (and therefore plastic) in the 1970s meant that fewer than 100 were ever made. There are thought to be 60 still in existence, one of which is currently sitting on the roof of Central Saint Martins in King's Cross. It was rescued and restored by the artist Craig Barnes and once a month he opens it up, lets people inside and talks them through the lengths he went to to save the house. There's more information, with photos of the building in various stages of dilapidation and renovation, on the house website.
