Help, we are building a self build conservatory, and have in writing that we don't need Planning permission. I have contacted Building Control and they say conservatory excluded, even though we go over a shared drain. We are planning to dig down to drain and support drain with concrete, and lintle over drain. Do I or do I not need building control involved !! They have been quite dismissive, but reading mail on here, everyone seems to say you do.
Thanks
