This had been plaguing me for a while. Many years ago - nearly 30 years - we made some changes to our house. We turned one small room into a bathroom, took down an extension at the back of the house, knocked down an internal wall between the tiny kitchenette and the back room, changed the doors at the back-installed an RSJ etc, added a small window. We didn’t get any buildings regs or planning done by the council -we simply didn’t realise we might have had to. The house is still fine and dandy. Only reading stuff on here makes me wonder if we should have. What’s best to do? Do we approach the council, or is it too long ago? Is it necessary or am I worrying about nothing?
