I found this site while looking for a how-to guide for timber frame houses, and just had to share it. There are plans for virtually anything! They were probably done in the 70s or something because I see asbestos and asphalt recommended.
Interesting. I didn't have that much of a look around until I found this http://bioengr.ag.utk.edu/extension/ExtPubs/Plans/6002.pdf . It is a 1 bedroom house, 24x24 and I know where there is one built exactly to this specification. Down to the window sizes and door placements, arrangement of the bathroom, everything identical! (it was a house I was interested in buying). That makes me wonder, how did these plans originate and how many homes were built using them?
