Had a couple of days off with man flu. Meanwhile, neighbour's been having work done. Making a right racket, heavy drilling at/near the party wall for several hours. The room's a kitchen - about 3mx4m. It's stopped now and this has popped out:
I don't think that's a normal extractor - it's way over the (what I thought was) standard. That must be 25cm . . .
Any idea what it might be for?
I would/will ask but far too ill to venture out :-)
