Structural Building Materials: There are numerous building materials that can be used for residential and small business buildings including some proven alternatives.
In earlier years homes and business buildings were built using balloon framing but in recent years platform framing has become the norm. There are advanced building materials and techniques that work as well or better than using wood (Aka: Stick built) for framing and these are covered in the kit.
Other materials that are used for rough-in construction are flashing and trim plus caulks and other compounds. Detailed lists of structural materials, techniques, and alternatives are covered in the GBDKit.
