In 1953 Utzon won a swedish architektural-competition on new types of small family houses. Utzon proposed a nordic atriumhouse, but his houses were never build.
Later on ,Utzon continued to work on the idea of atrium-houses and succeded to get through with an ambitious plan about building 60 atriumhouses in the outskirts of Elsinore, - the Kingohouses.
These were the first houses of that kind and became inspiration for many architects from the1960´s and till now.
