After researching many different types of housing for individuals, the houses built in Quixote Village appear to be the best selection for a couple of reasons. First, the materials are the least expensive (see material's list below). Next, the skill set used in the construction is easier to learn and more universally applied. Skills learned are framing, roofing, window & door installation, plumbing, hvac, electrical, etc. In addition, the size and simplicity of these houses makes it possible to build offsite and transport to the site location. This makes it possible for churches and other organizations to build the house at their location and transport it to the final site.
