Hi Bobby,
I found that picture on the web by doing a search of Japanese pages under 'azumaya' (written in Japanese characters) - so I can't refer you to a book for further pictures, and that picture was the only one on the page.
If you can find any books on Japanese gardens, you may be able to come across a picture of an azumaya, but I can't think of any titles in particular to refer ypu towards. Sorry!
There are some books in Japanese that I have which have drawings of designs for Azumaya, but those books are not available except from Japan - and they are in Japanese anyway, which i will assume you don't read. I'd send you a picture or two from the one I have, but unfortunately that book is in storage back in B.C. and I am currently in the Eastern US.
Thanks for your interest in the workshops . There is something scheduled for Spring in Seattle as far as what is upcoming. It will be a two week class.
Do you have the skills currently to frame a hipped roof? I'm afraid you will need to deal with a bit of mathematics for that, or have facility with descriptive geometry.
If you want something quick and durable for 10-20 years, requiring no math or geometry, then you might want to consider a wired-pole structure. There was an old Fine homebuilding with an article on that from many years ago. I've done it - it just involves learning how to do a simple knot with wire to lash timbers together. If the timbers shrink, the wire knots can be readily tightened. It's an idea.
