Prefab houses are pretty awesome. Dense living is definitely awesome. And Sustainable Living Innovations is getting the prefab peanut butter in the density chocolate, designing modular high-rise buildings that unfold like cootie catchers. This video shows how it works.
The result is a block of modern, open-plan apartments that is LEED Silver certified, and maybe a little ugly from the outside but no more than any other high-rise. It costs about the same to build as a conventional building, but takes as little as half as long to construct. This is perhaps not welcome news for Teamsters, but the idea of easily-erected, efficiently designed urban living is good for the rest of us. (We'll all have to wait for now, though, because SLI hasn't figured out how to get the buildings up to code. There's always something.)
