The strawbale studio is built post and beam and the roof erected before
bringing the strawbales into play...that way they were not exposed to
possible rainstorms prior to enclosure.  A concrete footing is waterproofed
beneath the bales.  The roof has 3 foot (1 metre) overhangs all around to
act as a grand umbrella.  The bottom metre of the outside wall has
waterproofing material placed over the bales prior to application of stucco
exterior, which helps to protect from "splash".
