I have liked the concepts to do with natural building since the 1970's. The latest edition of Fine Homebuilding has an article in it about the history of homebuilding in the USA. It discusses how the industry got off track and possible solutions.
In Canada we have followed the building trends of our southern friends. It is sad to see unsustainable homes being built now. I hope to see more green building happening in the near future. Our Guild members have lots to contribute to green building and new trends in Timber Frame construction.
