Environmentally Conscious

We believe that the Built environment meets principles of ecological sustainability.


The intention of sustainable design is to eliminate negative environmental impact completely through skillful, sensitive design.


Built Prefab designs its homes as a system. Our focus is on creating a superior building envelope utilizing the latest techniques in creating superior weather, air, water and thermal layers and increasing building performance through efficient mechanical systems.


Our operations focus on continuous improvement and the ongoing reduction of waste.


By building each structure offsite, there is less traffic, fewer disturbances to the land and reduced construction schedules all benefiting the environment.
