Well, Markus, except for the complicated joisting, the "plans" are pretty much represented in the pics. Help yourself.
And, if you are serious, I still have the blueprints somewhere of how it all works. Google "Marpa" and take a look at some more of Martin's work. You will see a common theme as with many designers. You might see a tea house you like better.
Another story: We also worked with another local designer from Pasadena named Van (somebody). He's pretty famous, too. This was when Martin was running out of ideas with respect as to how to tie all of this to the house itself. There was no direct way from the house to the garden. So, Van what's-his-name comes out to look things over.
One afternoon after we had finished (I had hired a furniture maker as a helper) sanding the decks ready for the tung oil finish and left for the day, ol' Van walks down a dirt path picking up some cement powder on his shoes (from another part of the project) and walks up on the deck. As anyone might know, cement makes wood black. The next morning, I could see every footprint on this beautiful wood. I could have killed this bastard. Another jerk.
I've never been able to work well on large projects with a lot of people involved. The incompetence and stupidity is overwhelming. We have a guy here on Pelican who goes by "lonewolf." That really should be my handle.
