Hi All, i have just submitted an application for building control, to remove a load bearing wall on the first floor of a two storey detached house. We have been asked for structural engineers calculations, which we have now organised, but the inspector is also talking about fire regulations, measuring windows and insisting on mains fitted smoke alarms! All we are doing is removing a wall between a large bedroom and a very small bedroom, so that we can balance them with a stud wall. No windows will be affected and no escape routes etc. The main landing will remain untouched, so can they insist that we fit mains smoke alarms? I know that this they are a good idea, but we'd like to fit them at our own convenience, not theirs! :?
Fitting a couple of interlinked mains alarms is not a major expense, I'd be more concerned about the window issue, they may insist you modify/replace windows which do not have a clear opening for escaping.
The Building Control Surveyor is wrong. You do not need to upgrade anything as you are only doing a sructural alteration. You are not doing anything that will materialy alter the means of escape, and you are not extending the property (i.e. adding an additional bedroom) The situation is no worse than it was before. Challange with his boss or Tech mananger.
