We did go via the architect, who instructed the engineer to do revised calculations. Does this help our case?

The missing chimney was directly over where they put the staircase, so had to be redesigned. The beam structure was very different to the original plans also. We have 4 beams instead of 1 (which also cost us a fair whack in extra steel!)

I will be having a chat with both engineer and architect shortly, I just wanted to understand my position a bit better before I make that call. So thanks very much to all posters the advice is very helpful.

I'm a bit confused. If the chimney is above the new staircase I'm guessing the chimney is redundant with no live flues? Surely it would have been cheaper to just remove the chimney?

Anyway, if it required 4 new beams and possibly some changes to the floor the engineer should have been able to do the calculations for around £500. I would be asking the architect how he missed the chimney and how much of a contribution he would like to make to the engineer's re-design fee?
