(I am the author) Yeah there are tons of architects that specialize in traditional (and even ultra-traditional reproduction) custom houses. But I don't have that kind of money. I needed to simplify as much as possible and do as much as possible myself while trying to keep the spirit of the thing I wanted.

Still if I had the money I suspect I'd want to be very involved in the design. Your living quarters are not a trivial part of your life!
