Fair point woody, but what if the 'professional' disappears a few years down the line.....you maybe left scrambling a bit?
Cutting a few inches off a proposed extension isn't really a redesign is it? I guess it depends if the OP is gonna be using somebody who is reasonable, or alternatively will try to take them for a ride.
I'd propose submitting the drawings for the Cert. with dims taken off, but showing the new extensione line flush off the existing cormer. If they pick it up fair enough, but there's no need to point it out with a dimension saying 3.1 or 3.2m is there?
So in my opinion anyway, still say go for a Cert. of Lawfulness.
