Earth Architecture. Eco Homes from the Earth: Rammed Earth. Wouldn’t it be nice to own your own green dream home, made with recycled and natural materials and packed with custom features? Whether you’re an experienced builder or have never picked up a power tool in your life, you can build a natural eco-friendly home with user-friendly, low-cost materials like cob, cordwood, straw and the dirt and wood from your own land.
These natural building techniques produce beautiful homes with a small ecological footprint and tons of personality. Rammed Earth (images via: rogers rammed earth) Fireproof, termite-proof, storm resistant, extremely low-maintenance and literally dirt-cheap: all of these qualities make rammed earth an attractive natural DIY option for owner-builders.

Earthen floors are ubiquitous in most of the world. They are the most accessible type of flooring to a vast portion of the human population. In the modern world earthen floors are still something of an oddity to most people, that is until they step foot on one. And then they are hooked for life. As a simple mixture of sand, clay, water and fibers, more and more people are installing them in their new modern homes with stunning results. Today’s practitioners of earthen floors are able to create extremely beautiful, deeply rich wearing surfaces in our most refined spaces. The techniques used to accomplish such enjoyable surfaces have been honed through trial and error by a handful of people who readily share their knowledge. Any modern home being built today with natural fibers or earthen walls should also include earthen floors. Sukita Crimmel and James Thompson have put together a work of art matched only by the sheer beauty of their floors.
How to build a durable Adobe Floor. An adobe floor, or earthen floor, relies on the sticky binding properties of clay...one of the most versatile building materials I know of. Clay expands when wet, creating sticky platelet particles, like a bunch of suction cups. Add to the clay ample course sand, to increase compressive strength and control shrinkage as the clay dries. Finally add fiber, to increase tensile strength and knit everything together, like reinforcing bar in concrete. The finish mix is essentially the same as adobe or cob. A typical adobe floor includes a build-up of layers, each with a purpose. You want your floor to rest on solid ground (or a stiff framed floor with little flex)...movement below translates to cracks up above.
Next you install several inches of gravel to provide a capillary break that prevents any potential liquid water in the ground from rising up into the floor. . #3: The vapor barrier Next you lay a vapor barrier that covers the entire floor area. . #4: The insulation #5: The base layer.

We are now onto building the second rammed earth wall in the UBC botanical garden. This wall is 55 feet long, curved and fades into the grade. Thanks to Katie who works at the garden for providing a few of the pictures scattered through our posts on the amphitheatre. The footing for wall 2 is ready. The round circle to the right is where the fountain will be going. Putting up the walers. Adding sheets of plywood to the walers. 1 side of the forms is now up and defining the shape of the site now.
Not every day can be sunny so here we are putting up tarps in the rain. Rudy is a happy man now that the sun is back. Delivering material up the hill. Quality control on the rebar placement. The pneumatic ramming in dramatic fashion operated by Rama. Ramming is complete. Beautiful layers…we love these walls. Wall 2 from a distance, it will eventually have a fountain if front of it. We are totally delighted with the wall texture and layering. The walls are tarped and this part of the project is done.
