We asked at our building regs dept about removing this wall and told we to ensure there was escapements from upstairs windows as a fire in living room would prevent getting down the stairs. We’ll probably put rad in place of door to kitchen from hall as we’re going to block it up.
Hi Kenneth, that’s a slightly tricky one. It will partly depend on where the existing pipes are and their diameter. In our house they radiate out from the boxed in flue and are microbore which fit through the small gap between the ceiling and floor beams. I’d probably go for the wall between the living room and kitchen/dining room.
Removing a wall that encloses a staircase does remove a barrier to fire spread, whether significant or not I don’t know. Personally I wouldn’t like the stairs to open into the living room, but that is personal opinion.
