Specialty builders Jon and Amanda D'Aleo design and build "earth-sheltered" homes for clients in southern Colorado, but they weren't expecting a project this far off the grid. They'll have to work overtime to get a house constructed and buried before the Colorado winter hits.

He teams up with world-renowned natural builder SunRay Kelley to experiment with a never-before used building material: mushrooms! Follow along as they not only design a mushroom-shaped house but virtually grow one.
