Here's a list of the Traditional Layout books that I have. Some of them are the same books, french vs german. These are not roof framing books for stick framing. These books are for the art of line. However, anyone wanting to be a master roof framer must be able to build a roof using geometry only and these books present the different geometric layout methods for using the art of line to draw out and build any type of roof. Also, there are some angles that just can't be calculated with a calculator.

Buy the books in this order:

The new Book on the ancient knowledge of Roof Framing
by Bernd Küppers.

Bernd's book is the first book written in English on complex roof framing geometry.
