i'm using an architect, which when we first met it all was great we discussed what we wanted, we agreed that a deposit would be paid and the rest in instalments. then the plans came back, entirely different to what we had requested, so we ended up giving the architect plans that we had drawn up a few years earlier. the plans that came back pretty much resembled what we had given him.
There was a problem with planning and the architect had to slighty revise the plans, a simple set back on the extension, everything got passed, but now he says he wants another £275 for the revised plans, or he won't release the structural calculations. I really feel that he didn't do much apart from the slight change on the plans we supplied to him. also the agreement of all the other charges to be paid in instalments went out the window, before he would submit the plans to planning he demanded the balance in full. he will never answer my calls only email and txt messages. can he just add this extra charge after everything was previously agreed.
