Hi, I have applied for building consent and signed a statutory declaration which was required by auckland council that states "I will carry out restricted building work myself or with the assistance of unpaid friends and family members"

Also may father in law has a mill to supply 90% of the timber

The council don’t have any figures based on my situation so wont to place my project value application fee higher then needed,

Where do I find supporting historic prices for my problem above to send to council as proof ?

cheers
Brett
