If you’re having trouble interpreting the CAD drawings of your new veranda, we can certainly try to explain them to you – and if required, we will even visit you to mark out approximately where the posts, front and wall plates will end up.  However, it is your responsibility to satisfy yourself that the drawings accurately represent what you require – and if you have any doubts we suggest that you contact an independent qualified professional to help you.  We cannot accept responsibility for any mistakes unless what you receive is materially different from what is in the plans.
