Interesting... and yeah, how did you guess? Into a boiler cupboard? Or rather, almost into, but next to, another foot and it would be.
Other freeholders can do one, bunch of jokers. Will contact council though. Thanks!
edit: sod that, just seen the form, just going to do it.
@chrisbmx116 Just because it's a drywall doesn't necessarily mean it's not structural.
Are you widening a doorway into a boiler cupboard? got any floorplans you can show?
And, technically, yes you will need permission from the other freeholders.
Building control approval can either come from your local council or an approved inspector (a privately run company)
