Thanks for your help, there are no building defects that I’m aware of at the moment. So far I have been our developer / builder have been 100% straight with us and I have no complaints. Given our experiance so far I would imagine any potential problems will be fairly resolved.
I will keep a record of your response and refer to it if I need it.
But to be clear, if building faults, snags come to my attention do I complete or not?
