I am applying for planning permission to install a new staircase up into an attic trussed loft therefore converting the property to 3 storeys. The foot of the staircase is in a storage room (not a bedroom or otherwise habitable room) which has a window in it. The door to the storage room leads onto a landing which then has bedrooms off of it which have fire escape windows. The new loft area will have a patio door leading onto a small balcony. My question is, does the window in the storage room need to have fire escape provision as it currently doesn't and I don't want to replace it.
Many thanks in anticipation,
Alan T
