Planning and building a tiny home

TinyHomeDIY is a resource wiki for building your own tiny home. It's 2017 and there is a ton of quality info for planning your tiny home, right here online. The most practical sources are blogs by individual builders who detail their decision-making processes, materials, methods, costs, and the problems and solutions they encountered. Distilling all that knowledge with common sense should result in a DIY master plan that's as close to foolproof as humanly possible. That's the attempt here, to synthesize, giving full credit and sources.
