Well, it’s certainly more than just mud and straw! Natural Building is a construction and design methodology that utilizes minimally processed, naturally occurring materials, which are often locally and sustainably sourced.

Choosing to design and build with natural materials is important not only for reducing the environmental impact on our planet but also for creating healthy, non-toxic living spaces that we, as humans, need to thrive.

Think of building codes as guardrails. For the most part, we take them for granted as we drive over bridges or navigate curving roads. But in those unfortunate cases when we need them, we’re glad they’re there.

As is often the case with most building and design topics, the classic response is, “it depends.” However, we can generally say that if your project or site can safely support infrastructure, there is a natural building system that can be utilized for it.
