I was half listening to one of those home renovation programs over the weekend and I thought I heard them say that planning permission (as opposed to building regs) was required where a steel beam over 3 metres in length was required, though I didn't hear what it was to support.
I've done a search but can't find anything about any 3 metre limit, is there such a rule/reg?
