We have included one sample page from the plans in this web site. The plans are written for the average person and first time builder. The most important skill required is the discipline to consistently read and follow a large number of written instructions. You do not need to be an engineer to understand the plans. They consist of over 100,000 words, over 1,000 illustrations and photographs, and full size drawings to lead you step by step.
