Hi, I am wondering as to what people's experiences are on the differences between what a Quantity Surveyor prices things at as opposed to what the 'real' costs for work are? I have been told repeatedly by two architects now that they 'overegg' everything. I am needing to do house renovations (we have recently bought a 1800's cottage with low attic rooms) to get my infirm parents moved in with us. Thank you.
