We'll probably need to complete the space elevator before any sort of large scale extraterrestrial construction becomes really feasable. I heard a quote on that for about 2020, we need to increase our technology surrounding carbon nanotubes a bit first. It's supposed to reduce the cost of transporting materials to space to only a few thousand dollars a pound or less.
