slr2679 Posted March 1 Posted March 1 (edited) Hello. Looking for some advice re the need for fire doors. We have a dormer bungalow, so there is an existing front dormer and bathroom upstairs as per the original build in 1968. We have planning approval to install a rear dormer and in the architect plans, they include all doors to be installed/replaced with fd30's, even including the bathroom, downstairs wc, foyer door and under stairs cupboard door. I'm not sure if this is a requirement under building regs as all the information I can find relates to the build of a dormer/loft conversion in a bungalow where there is no reference to existing rooms in that space, so therefore there is the addition of a second floor in the roof space. There are three other bungalows with the exact same build situation on the the same street, who have had works completed in the last 6-18 months and none of them have had the fire door requirment with their plans and all have been signed off by building control. Is anyone able to help clarify? Thanks so much in advance for any help or advice Edited March 1 by slr2679
Mike Posted March 2 Posted March 2 No, you don't need fire doors if you're converting the loft of a bungalow. Building Regs Approved Doc B1, section 2.21, requires fire doors only "where a new storey is added through conversion to create a storey above 4.5m". My guess is that they've copied and pasted from a previous job. 2
DevilDamo Posted March 2 Posted March 2 Do all upper floor habitable rooms have an external window or door that meets the escape window requirements? 1
ETC Posted March 2 Posted March 2 Standard two storey house fire doors not needed (except between an attached garage and dwelling). You’ll need EEWs to new created bedrooms on the first floor. No new rooms = no new EEWs. 1

But having read through Doc B1, point 2.10 for the general provision of an emergency escape window states 'The bottom of the openable area is a maximum of 1100mm above the floor' so not sure if that means we won't be able to use this as an option? Sorry if that's a stupid question. I want to make sure my ducks are in a row before approaching him with the information. Edited March 2 by slr2679

Don't forget - if you are NOT introducing a new bedroom AND you didn’t have an EEW in the bedroom before you did the work BC won’t ask for a EEW. Edited March 2 by ETC

Thank you, so just to clarify, that measurement for the window from the floor is internal as I was reading it as external!?
