Hi, 

I am after some advice regarding 'inner rooms'. We have been asked by the School to provide a quote for installing a stud wall in the middle of an open plan room with an opening but without a door installed to prevent 'inner rooms' been created. Does this comply with Fire Regs if we leave the Door off, therefore essentially it is still one room? 

It's in the spirit of the guidance, although if the access room will still have a smoke detector in it then  not quite necessary - you can have the vision panel (or no door) or access room detection or finish the partition 500mm below the ceiling.
