materialicious covers a different sort of prefab product that's been around for a while. From the company site:
The Igloo Satellite Cabin is designed to provide safe, reliable accommodation in remote areas. It has been used for over 25 years in conditions ranging from the tropics to polar icecaps. Units can be flown by helicopter fully assembled, and often fully equipped, to locations inaccessible by road transport. Igloos are ideal short-term accommodation for exploration and research, as well as an attractive alternative for eco-tourism.
Igloos can be lengthened to six or more metres by adding sets of extension panels, or interlinked by tunnels to provide a complete weatherproof base.
The Australian Antarctic Division has a bit more info on the history of the cabins:
2007 marked the 25th year since the first fibreglass Igloo Satellite Cabin was designed and manufactured in Tasmania. As at January 2008, 159 Igloos had been purchased by 45 institutes and individuals in 18 countries, with the majority for use in Antarctica.
