About Us

Our Values

We started our company to address the need for truly sustainable construction company for homeowners and businesses in the Front Range of Colorado. Our values are important to us, and we try to honor them in all aspects of our process.



Build using materials that are found or produced locally and have as little embodied energy as possible. Use local labor to build the local economy.



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



Not only do we want the inhabitants and environment to be healthy, but also the building itself.


Low Impact

We use materials with low embodied energy, sourced using the least extractive methods possible.
