We are Bill & Stephen Betzen, a father and son team who started the planning process in 2004 to build a rammed earth home in Dallas, Texas by 2009. We are on schedule. We want to share research we have done and make connections with similarly interested Do It Yourself (DIY) people also interested in rammed earth construction and benefits.

Our home is planned to be a 2400 sq ft, 2 story home with a covered balcony and porch surrounding the home. The ground floor earthen walls will be 2 ft thick with 18" thick walls above the second floor. The goal is a home that will be as cool as possible in the hottest Dallas summer. With a home fully surrounded by both a shaded porch and a shaded balcony, as well as many trees, we hope the worst Dallas summer sun will never heat the thermal mass of the rammed earth walls. Combined with a ventilated, reflective metal roof over insulation, we hope that annual air-conditioning needs will be greatly reduced if not totally eliminated.

Our research shows rammed earth construction to be the most simple, environmentally responsible method for building the thermal shell of a home. It will be a strong, quiet, healthy, termite-free, fire-resistant, comfortable home, one weighing 300+ tons and lasting many generations. It will save thousands of dollars annually in utility and maintenance costs along the way.

Some of the negatives of building anything is that there is a footprint. We tried looking as many locations for the building and the one we settled on happens to cover 2 beautiful cedar trees. This location was the best location…

On 1-14-12 I drove with a good friend to show him the rammed earth work that was already happening in Dallas. We drove to the work being done at the facility just east of the Walnut Hill Lane Dart station. As we looked over the…

Unfortunately This project has been put on hold once again. The city shut us down... but the good part is that it had nothing to do with it being rammed earth. They stopped the project because they said we could not have another…

Eight questions collected on the design chosen, why rammed earth stayed rare in Dallas, what changes for a Texas summer, what the work was expected to cost, and whether earth walls stand up to heavy rainfall.
