Almost all the wood was certified by the Forest Stewardship Council, which verifies it was grown and harvested in local forests in a sustainable manner. The rest of the wood was either reclaimed or salvaged, including wood from a hickory tree used for flooring and wood from a cherry tree used to make the dinner table. They weren’t able to find an FSC-certified cabinet shop in Michigan, so Beacon Springs Farm became a certified site and the Burbecks hired a carpenter to specially make cabinets and doors for the home onsite. Some of the reclaimed materials in the house include a bath tub, chandeliers and light fixtures.
