Interested in building a log cabin from scratch, just like our pioneering ancestors did? Well, I haven't found a web site yet with step by step instructions, but "Cabins: A Guide to Building Your Own Nature Retreat" is a pretty good book to check out.
It goes into how to build different types of cabins like pole-built cabins, stick-built cabins, post-and-beam cabins, stone cabins, and cordwood cabins. It doesn't have any big colorful photographs, but there are a lot of sketches and drawings showing cabin plans, designs, and constructions tips. There aren't any actual blueprints though, so I probably wouldn't recommend the book as a definitive guide to building a cabin from scratch, but it looks like a good jumping off point. It really gets you thinking about everything from where to buy land (what to look for when you buy) to the nitty gritty necessities (foundations, insulation and roofing, plumbing & sanitary systems, etc.).
If your libary has it, it's worth reading even if you're planning to have someone design and build your cabin for you. It's about $13 for the paperback version at Amazon: Cabins: A Guide to Building Your Own Nature Retreat
