Room with a room - 2x3 instead of 2x4?
Has anyone used 2x3 stud work for a room within a room, instead of the normal 2x4?
Room is only 12ft x 13ft - I'm in the UK and rooms tend to be much smaller here I think. Studs will be then 16" or 24" centres. Single layer OSB and then drywall. Will the structure be rigid enough and be able to support decoupled joists?
I'm sure I've seen it done before, but I know most on here go for 2x4 timber.
