Does anyone know what the rules are with regards to having an open plan kitchen on the ground floor with stairs to the first floor. Does there need to be a door between? Do all of the upstairs doors need to be fire doors? Do things change if a loft extension is added? Any advice much appreciated.
How many floors are there in total ? In general if there's more than two floors you need to keep the stairs and exit safe from fire, so open plan is only possible if you install a mist or sprinkler system.
At the moment we just have two floors but I would like to convert the loft at some point in the future. Downstairs there are four small rooms and a large hall and I would like to open up to over the rooms to hall. Any idea how much a sprinkler system costs if that's whats required?
