Straw Houses on a Firm Foundation
Habitat for Humanity goes low-tech with big results.
February 3, 1997
With gray clouds overhead and a biting wind whipping across Tucson's desert hills, many Arizonans early this Saturday are indoors, sleeping in.

The straw-bale home, constructed by volunteers with Habitat for Humanity, Tucson, is part of a model project to demonstrate how straw can be coupled with solar energy to build better homes at a lesser cost for low-income families. Habitat Tucson was chosen by the city government to partner with the Tucson Urban League for the model super-insulating, straw-bale home effort. Habitat also received a grant from the National Urban Consortium to help with the construction costs.
Low cost, low maintenance
A house of straw? It's no longer just for the three little pigs. As modern research has discovered, straw-bale homes provide temperature insulation three times greater than conventional new homes. ...
