Adding a Dormer to a pre existing loft conversion

I already have a loft conversion but I would like to extend the back of it out by adding a dormer in order to add more height and space as it's currently got an apex roof. How much would it cost to just straighten out one side of the roof to a flat top roof style dormer?

"Price all depends on size , for a 6ft wide dormer would be around £5k -£7k and a full width of roof would be around £30k . These are rough prices for complete dormers , finished inside and out"

"Hi there, do you have any plans drawn up for this as it would be very difficult to price up without them"

"It's difficult to give an accurate price without any plans or measurements, however, as a ball park figure I would say around £25,000 to £40,000. It's a big range but as I mentioned, without any plans or measurements it's difficult to say."

"Hi the price is according the task we need to do but you looking at £35,00] to £45,000 depends the size of the loft extension."
