A tiny earthbag house

05/02/2009

Earthbag construction is one of the newest types of sustainable building techniques. I’m so inspired by this little earthbag dome that I just might have to build one someday.

This igloo-like tiny house was designed and built in New South Wales, Australia by Rob & Steph and a steady stream of eager learners. It is 13 ft. in diameter and utilizes passive solar design and a living roof.

They used 700 cubic feet of fill sand and about 700 total man hours (not including finishing work such as plaster, windows, doors and flooring). Total cost was $2,500.

Here’s the view looking up at the loft.

Yes, it does look really nice, but 700 man hours just for the shell?! That’s WAY too much effort for the end result.

Hi Neil,
Michael agrees with you — way too many hours. To their credit, Rob & Steph had to spend a lot of time training the people who came onto the project. They wrote that they could cut the hours by two-thirds if using a consistent team of 3-4 people.

Is the ledge around the roof for collecting rain water?

Yes I believe they are collecting rainwater.

Over here in the states, we have Cal-Earth that creates structures in a similar method. What did you use for your bags? They look like plastic?
