Earthen/Cob Floor

Straw Bale Build in Fairview, Utah

“When this home is finished and you walk into it , it will be like putting on an old pair of Levis. It’s just extremely comfortable and personnable.”

This (4H?) video shows a straw bale house under construction in Fairview, Utah. The house is a wooden post and beam house that uses straw bales as in-fill material (versus a structural straw bale house that would use the bales as support for the structure).

At the time of the video all or most of the straw bales are in place between the wooden joists and the all-ages work crew is focused on finishing the interior walls with a home made plaster (a mix of mud, sand, wheat paste and straw).
