We’ve been living full-time on rainwater, thanks to our whole-house rainwater filtration system that delivers clean, potable water for drinking, cooking, bathing, and laundry.

With good southwestern exposure on one long side and a growing interest in extending our planting season—not to mention protect plants from all of the elements and critters that do a good job of killing or eating them here in northern Arizona—we decided to build a lean-to style shipping container greenhouse, and it's become a year-round space for a variety of edibles.

This innovative building material combines the strength of concrete with the insulating properties of recycled foam.
