Looks good Chris, and pleased to hear it's still standing. I want mine to be about 4-6 times bigger covered area, because I want to be able to sit out next to the smoker, I also want to be able to fit a sturdy table in there to prep meat on.
Unfortunately, because of the orientation of our garden, if I were to go down the route of only fixing to the wall, I fear it may blow down in the wind.
