Damp Proofing Question

Damp and mould in upstairs bedrooms

Hi, I live in a 3 bedroom house with my fiancé, our 2 other rooms are empty most of the time (the 2nd bedroom is used when people stay the night which is not very often, the 3rd bedroom is just used for storage). We have the heating off in both rooms and the windows shut, so this time off year it is quite cold in those 2 rooms.
We have just been in the 2nd bedroom and noticed damp and mould on the outside wall and ceiling, in the corner next to the disused chimney breast. The chimney breast goes into the next room, the 3rd bedroom, which also has damp and mould forming on it. It is very difficult to get into the loft to check damp there, we have a very shallow roof. The roof from the outside looks ok, no missing tiles. Is this just a condensation problem? It worries me that there is quite a large damp patch in one of the rooms, about 1sq foot.
The house is dorlonco construction, steel frame and concrete, and we don't have wall ties.
Thanks in advance for your help.

The type of construction does help condensation form,its a pity you can not check the loft in this area as it may not be insulated properly which could also add the issue try to vent the rooms to allow for some air flow as poor ventilation is the most common cause of this type of damp.
