Headwaters Seat Covers is a manufacturer of high quality custom seat covers located in Three Forks, Montana. This year, they decided that they needed more space. We built a 600 square foot commercial addition and tied it into the existing building. The addition sits on a concrete slab and has conventional 2x6 wood framing. The exterior has metal siding, roofing, soffit and fascia and the interior is also finished with metal.
