The Colorado-based Formworks Building Inc. has been specializing in earth sheltered building technology since 1979. The main idea behind their buildings is the creation of sustainable, affordable housing. Formworks structures have an estimated usable life span of over one hundred years without any major maintenance. These houses are built into the earth surrounding the building site, which has the added bonus of protecting the home from raging storms, tornadoes, hurricanes, fires, mudslides and so on.
