A prefab home designed by the University of Illinois Small House Council

Here's a different kind of prefabricated house. It doesn't come from factory or prefabrication dealer but from the local lumber yard. It is built of standard 4' x 8' wall panels (there are solid panels, window panels, door panels) and roof trusses which can be assembled by the lumber dealer and put up by any builder. This system was developed by the University of Illinois Small Homes Council who also designed this compact 1,008-square-foot house.
