Creating a small office/gym in detached garage

Hi all, we have a detached double garage and I am wanting to create a small (8ft x 8ft) “box” to use as a home office when working from home, and as a gym. Will be relatively temporary

Planning to use 63mm CLS studwork, with 12.5mm plasterboard on each side. Not bothering with skimming etc. 3 walls will be internal, one will be external, against the single skin garage wall. Am I right in thinking I need a damp proof membrane here? I have a load of rockwool left over from doing our loft, so was planning to put this in the walls too.

Whole garage ceiling is already done in t&g chipboard, so will be adding some rockwool above this.

Garage floor is concrete, what would be the best way to insulate this a little? Again, I assume a plastic sheet damp proof is needed?

Thanks, any advice appreciated.
