Welcome Rikki,
It looks like you intend going to a lot of effort to make sure your CT build is:
# Safe
# Legal
# Covered by insurance in the event of a claim..
Once you start reading many of the build threads on here - you may be surprised to see how many backyard jobs don't seem to be that concerned about these matters..
You being a responsible builder - I will be very interested in following how you go with everything...
Very well done indeed for the attitude to want to do the right thing... Our country needs more of this, I reckon..
