Need to increase room size of 0.2 m2, per HMO regulations

[badhairday]

I have a house that I have been renting out to sharer's. One of the rooms is 6.32 m2. Too small to be rented out by 0.2m2.
I was hoping that replacing the plasterboard with a thinner plasterboard might do the trick, but honestly, there is still not much space. It was already optimally used. Can anyone recommend an ultra thin plasterboard?

Hi,

Changing the plasterboard seems a pretty drastic solution that might not buy you those extra 2000cm2!

For a start, I would get a definitive set of dimension, are the walls truly parallel and are you measuring above the skirting boards etc.

If you can post some pictures / plans, we may be able to come up with some ideas.

For instance, can the door be moved further out of the door frame?

I also hope that the occupant of this room is going to get a decent discount!
