Also, I'm looking to purchase book(s) on designing and building with raw timber framing type construction. Any suggestions on what I must have and what I should not waste my money on?
I have printed a book list here on this forum section, I'll have to find it and bring it to the top of the list, but you should try and learn how to do "square rule" joinery. It is described in Jack Sobon's second book "How to build a classic timber framed house". If you go the the timber framers guild website and look in their online store under publications you should be able to see and purchase a copy.
When people tell me this is idea, cut my own timbers and make my own addition, I usually tell them to start by having a conversation with their building inspector (if you have one) and see if he will allow it do be done at your site. Sometimes it's no problem, sometimes you have to meet his rules and requirements. You need to know whether or not you can actually do this at your home.
And with just about every timber frame being a unique thing, it's hard to find a set of "stock plans" that will fit your needs. Most frames are custom designed for the client's needs and location.
