We're thinking of converting a walk-in pantry off the kitchen into a downstairs toilet.
In the belief that you can't have access to a toilet from a kitchen, the idea is to put a studded partition across the pantry around a foot in from the door and hang shelves from it. Behind the partition would be the new toilet with access through a door newly installed in the hallway/pantry wall. Drainage would be through the wall opposite the new door and into an existing cast iron toilet downpipe which runs down the inside wall of the garage.
I'm sure that all of this would need building regs permission (but not planning regs) but I'm being told that I'm wrong and no permissions are needed. Can we really go ahead with this with no permissions?
TIA
