Readers liked Caleb Schafer's $70k Simple Modern Home, so I thought it'd be interesting to quickly mention his thesis project, which was all about green design and construction. The project was to design and build a modern, straw bale bunkhouse for his parents. Caleb and his dad built the structure with reclaimed barn beams (power washed and sealed), reclaimed Malaysian hardwood flooring, local straw, locally harvested lumbar, and materials from the Habitat for Humanity ReStore. It's a reclaimed straw bale bunkhouse!
Update: Caleb tells me they spent a total of ~$15k to build this.
