concrete ceiling/one brick wall condensation probs

[laneycakes]

Hi

Apologies if this is the wrong forum...Couldn't decide where this should go!

I've got a major prob in my house to do with condensation (which i know has been talked about a lot but my case is slightly diff to all posts i can find!)

one bedroom is part of an extension - it has a flat concrete ceiling, and the outdoor walls are only one brick thick, no insulation then plasterboard/skimmed. I'm getting major condensation in the corners on the ceiling (huge droplets of water across the whole corner, and above the window, as well as black mottled patches) as well as a small amount of condensation on the walls. I'm toying with looking at drylining for the walls - but any suggestions on the ceiling? one though was to lower the ceiling a couple of inches - leaving an air space, maybe some insulation and then a new layer if plasterboard...would that work?

As you can prob guess i'm no expert on building! any help appreciated

you need some serious inso' at this junction to prevent cold bridge.

messing around with dry lining and small air gaps will not be enough.

you need to fix insulation board or inso' backed plasterboards to the walls and ceiling as a minimum.

why the reluctance to fit insulation?

no reluctance really - just not sure of best option. The concrete roof is flat so other than putting a new roof there's no insulation space...i'm afraid i'm clueless when it comes to this stuff!

Basically we need something that will solve as much of the prob as possible, but as ever for the cheapest cost and minimal disruption. there is enough height on the roof to drop it a couple of inches but i don't know what we could do about the walls!
