Never having done an extension before, we paid an architect to draw up plans and see thru the process of getting permission. To cut a v long story short, he made basic admin errors (getting our address wrong, twice) which meant that 7weeks on from when he had told us we could expect PP to be thru, we are about to go on holiday still not knowing. We had hoped worst of building work would be done while we were away: instead we have not even been able to book the builder in. Architect has given loads of false hope dates, but is now saying "what do you expect me to do?". What can I expect him to do?
