We decided some time ago that we'd really like a pizza oven, and deliberated for ages on if we'd get enough use and where it could go. In the end we made the decision and decided to put it off the end of the outhouse and turn that area into an outdoor bush kitchen type area.
So stage 1 was to push the back wall out 400mm to make room for a bench along the back wall, and to ad a 600mm extension off the front for a seating/prep bench area, and the shade cloth roof was redone with old corrugated iron.
