Roger Warren just sent this, along with this description of his studio on an island in British Columbia:
Something you have never mentioned in any of your books (I have them all): Any building should be designed around multiples of 4. This fits in with standard construction lumber; i.e.: If you build 10 × 10, you (have to) cut off 2 ft. of floor ply.
I also designed and built the house, shown in my website.
I also have the same tools you do.
