Garage wall cavity or solid?

[MarcoM]

Hi my house is a 1984 Barratt house detached with attached garage.
I would like to know if the wall between joining the house section to the garage is cavity or solid?
The house is two storey but the garage only one. I think the garage wall may not be cavity but then I wonder if the wall
elevation above the garage would have been built as a cavity wall? would they have used a steel beam across the garage wall and then built the cavity for the upper floor on that?

thanks

Can you check the wall thicknesses or take some photographs?

It's most likely a cavity wall, otherwise there would be a greater heat loss into the garage from a single skin wall.

As above, deffo cavity if it was done nowadays and it’d be a bit odd if it wasn’t. Easy to do a hole and check

Cavity, and I've not even seen it!
