What is your favourite natural building technique for solid walls?
Is it Adobe, cob, rammed earth, or even h**pcrete? What are the reasons you prefer one technique over another?
We are genuinely interested and welcome robust and respectful debate.
As producers of ADOBE bricks, you could think we are biased. And, well yes, we are. We don't prefer Adobe because we sell bricks, however. After 20 years of making bricks, we can genuinely say we love this technique because it is simple, versatile, and adaptable to different climates. We also love that it is very low embodied carbon, or even carbon sequestering and that it is covered by the NZ Earth Building Standards.
We also love COB, and use it mostly in our historic restoration projects. The drying times of cob often aren't as commercially viable for us as a building contractor, but we love teaching this technique and seeing some of our students build beautiful cob structures.
We love the aesthetics and scale of RAMMED EARTH, but don't build or teach this technique, because we are not interested in the amount of shuttering and gear required, and we generally prefer a quiet building site. This decision was also influenced by the types of soil we work with, which are generally clay-rich and creamy. If we had a more rocky and lean local geology, we'd definitely consider RE.
We will only get into HEMPCRETE if we can make clay work as a binder. We work with lime for plasters, and that is quite enough... As much as we love h**p and lime, the thought of working with a caustic material day in, and day out having to wear PPE, and the higher embodied carbon of the binder makes this technique less appealing for now.
Our students often come with a preconceived idea of the
"ideal" natural building technique. We teach them to choose the technique that makes the most sense for their individual situation. Solid earth walls are often the simplest solution if building skills such as carpentry are limited, and if the building doesn't have to be transportable.

"CLAY" and I'I send you the link.
