Earthbag Studio Apartment
Specifications: 264 sq. ft. interior, fold-out bed, 1 bath, Footprint: 14′ x 26′
Description: This extremely efficient earthbag apartment utilizes all natural building materials and reduces energy costs. Building multi-unit structures reduces the number of walls required. They can be joined side-to-side and back-to-back. I used 24″ bags for this design for multi-story construction. Note: this plan is now listed in the free shelter category.

Can I get this plan free?
I’m too busy now to do free plans. The plan is simple enough you could figure out on your own with a little study.
