Hello
We want to knock a hole through an interior wall, which is load-bearing (it used to be the rear wall of the property before a single storey extension was added to the house long ago), to put in a window to let light through. We don't seem to be able to get definitive advice as to whether building control is required for this.
Can anyone help, please?
Thanks
J
PS - it's a Victorian terrace in London in a conservation area.
