Why wouldn't the wall have at least 30 minutes fire resistance. What do you think they would have built it of, and why would it be different to the 30 minute walls they would have built on the protected hall/landing
Btw, the requirement for fire doors is 20 minute fire door sets, not 30 minute fire doors.
The modern Part B gives little guidance on what spec is required for a stud partition to give 30 mins F.R. However, looking through my old 1851 edition of the regs, it does indeed state that a stud wall with 1/2" plasterboard and skim both sides would provide 30 minutes.
