At a superb location on the Baltic coast near Lisön, Ralph Erskine designed a vacation home in 1955 that also had to be suitable for year-round living. The client, Engström, was the owner of a steel construction company, and he collaborated with Erskine on developing the self-supporting dome construction of the house. The dome is comprised of 16 prefabricated segments of 3-mm-thick steel. It was meant to serve as a prototype for large-scale factory production, which was never realized. The ideas behind it show parallels with Buckminster Fuller’s Wichita Dymaxion House, the production of which also remained limited to a single proto-type. For both houses, new techniques that had been developed in the defence and aerospace industries were applied in order to come up with affordable, prefabricated homes that could be placed in different locations.
