Single brick wall in a garage conversion

Good evening,

I have a tandem garage that has previously been converted into a room at the bk of the garage but the outside wall with a door and window is only single skin each makes the room both cold and damp I'd like some advice as to how best proceed as its used as a bed room currently

"I would recommend putting a stub wall in front and using tantalised timber if there is damp if the wall I would recommend tanking at least a metre up the wall and then insulate the timber frame board and skim should feel slot warmer"

"you could build another wall in front of it and insulate this, you could either block a wall in front or tank the wall and then stud wall and insulate off from there"

"There are lots of ways to do this but the cheeping and most practical way is to build a stud wall internally with cavity insulation between the existing 4” brick wall then plaster board the stud wall and skim and place skirting boards for a warm seal."

"Some stud work and insulation is one way to look at this, as thermal bridging is causing you all the issues buy the sounds of things. Also worth noting- is there much ventilation in the space?"

"hi, you could add the Celtex insulation 50-90mm and close that with the plasterboard that will solve that problem"

"Brick or block up a new internal skin with dpc to stop any rising damp on this new wall. The timber frame it with insulation and plasterboard. Tape and fill to finish. The outside skin I would drill and inject a doc to prevent any more rising damp and the possiblility of it bridging to the new wall above the new wall doc
Hop this helps."

"Hi ,

You could build a timber/metal wall inside and fully insulate it like a cavity wall on a house . Also i would use PIR plasterboard to give you extra warmth and prevent damp ."
