Laurel bathroom wall addition

I agree about the stairs ending up in a room where I wouldn't want them too. This looks like a good solution! If you haven't permanently attached the new wall yet, I'd paper the tiny hallway and paint the ceiling first though, that's an awful tiny area to get your hands into!

Ah, hindsight! I didn't paper before attaching unfortunately. That's today's fiddle job. Keep your fingers crossed for me.

If you have problems doing it, try to loosen the glue with a heat gun or hair dryer, then replace the wall when you are done.
