Really cold bedroom and condensation

Hi!
I bought a doer-uper earlier this year and I've done a lot of repairs but one thing I haven't yet done is repair the windows or radiators.
but in the bedroom, I don't use. I noticed some mould on the skirting board this morning I have since removed it but the wall was really cold and had condensation my wall in my bedroom that I use sometimes just get cold but not as cold as that back bedroom. I haven't got round to renovate that room yet.

But I'm just wondering if anyone has any tips or tricks to prevent? It's a really cold room, but it does face the wind. I turn my heating on when it gets to 17 and heat the home until it's 20 (naturally I prefer a cooler home)

it's a 1960s flat

Thanks

I'd get someone to fit insulating plasterboard on the external wall.
You lose an inch or 2 in room space, but so worth it
We had this in a small bedroom and bathroom in an 1850's cottage and that (and new windows) sorted the problem.
We did get a decent dehumidifier to help too, but the main thing was those walls not being so cold.

Also used dulux kitchen and bathroom paint with 'mold-tec' in this rooms. Great stuff.
Tried the cheaper b&q versions and it was pants.

Edited

I'm against this as I don't really want to lose space in there in case I ever sell it's a flat as well so I feel like people want even more space in a fact not less space.
I think in summer, I will get someone out to see if any other brickwork needs to repointing on the balcony, as that isn't a job that can be done when it's cold and wet
