Architect Ralph Erskine’s unbuilt proposal of 1958 featured renewable energy and protection from the north wind. Lars Harald Westman, illustrator. [ArkDes Collections] A sturdy reindeer stands in the foreground of architect Ralph Erskine’s 1958 conceptual drawing, “An Ecological Arctic Town,” its head bowed toward a cozy, colorful settlement ringed by a circular megastructure topped with windmills and solar panels. The town opens to the sunny south and walls itself off from the harsh north.
