Hi, we have recently extended our kitchen and knocked through to the dining room. Our kitchen cupboards run down one side (the outside wall) of the kitchen and an island in the middle. The kitchen cupboards on the wall are absolutely freezing and there is such a draft coming from the plinths. Our plates/glasses feel like they have been in a fridge and things like chocolate spread is a solid block not spreadable, as silly as that sounds it’s an example of how cold the cupboards are. Why would this happen? And what can we do to stop it? It’s very upsetting after spending so much money.
Are you a tradesperson and able to answer this question?
Good evening,
The draft from the plinth could be coming from the bottom of the wall if it has had plasterboarded stuck on it with adhesive and the boards don't reach the bottom. If you take the plinth off and can see plasterboard and then bare blockwork then this may be issue and can be resolved by expanding foam in the gaps and the bottom of the boards. If this is not the case you may have a air brick on that side allowing cold air directly in. It is hard to say too much without being able to see the area

There is no way a new extension can ever be cold if built correctly ,best contact the builder and check the works have been carried to to building regulations and passed.
From the description the Cupboards are freezing so I would think that the wall has no or not enough cavity insulation i don’t believe a gap at the bottom of the plaster board would make the Cupboards freezing especially when the description said it was an outside wall
If the outside is built in brick it’s not hard to remove 4 bricks and inspect the cavity for depth and insulation if it had a 70 to 100 mm cavity and there is no insulation present it could be blown in , its not expensive and easily done that said your builder should have under building control ?!
I don’t think that is correct . Sounds like not enough insulation in cavity wall to me . Needs investigating . Chop out some bricks and investigate firstly . Does all the wall feel cold to touch on the inner skin ?
Dot and dabbing plasterboard would not cause the problem . Was it insulated board that was dot and dabbed ?
