Frank participated in a brief interview on green building in Colorado with Boulder, CO radio station KGNU. Both Living Craft and Rodwin Architecture were represented after our joint presentation at The Eco-Social Solutions 2018 conference at CU Boulder.

The Philosophy of Natural Building

What is Natural Building?

This is a hard question to answer, and has been the topic of many classroom and late night bonfire discussions. For us, it breaks down to a few basic principles:


We try to use materials that are found or produced locally and have as little embodied energy as possible. We want to support the local economy and the people within it. I would love to use bamboo, but if I have to ship it across the Pacific, it’s probably not the best material to use.


We use materials that are not harmful to the people producing, installing, or living among them.


Not only do we want the inhabitants and the environment to be healthy, but also the building itself. Too many of our new homes are riddled with moisture issues and bad air quality. By creating a vapor permeable wall system, we don’t trap moisture where it doesn’t belong. Instead, we allow it escape harmlessly, without negatively impacting the performance or longevity of the building.

Low Impact

Low embodied energy, with the least extractive methods possible. This allows an efficient building to begin immediately having a positive effect on slowing down climate change, rather than having to “pay back” the energy that went into and emissions that were produced while creating the materials.


This term gets thrown around a lot, and seems to have lost some of it’s true meaning. There are three tiers of sustainability: Economy, People and the Environment.


We want to use products that are literally dirt cheap. With cheaper materials, the customer saves money. Sometimes these materials require a little more labor, which puts more money into the pockets of local tradesmen instead of going to the large corporation.


We prioritize the use of local materials that help support people in our community. We also try to make sure these materials are non-toxic to anyone who comes in contact with them.


Our focus is on finding and incorporating into our design the materials with the lowest embodied energy possible. We also try to think in a cradle-to-cradle mindset. We want our buildings to last forever, but at the point it reaches its end of life, it shouldn’t contribute to the waste stream. With natural materials like clay, hemp, and straw, much of the building is compostable or can be put back into the natural environment after its disassembled.
