Thanks for the replies.
Indeed it is would add about 5m2 to the size of the loft bedroom, which isn't a great deal, but I guess there is every chance an inspector would deem the increased occupancy a fire risk.
Hi guys, I'm wondering if anyone can help me please, as I can't find anything on the internet about building regs on alterations to existing loft conversions.
Basically our loft was converted 25-30 years ago and has a building regs certificate, so it was signed off when rules were more relaxed...
