I'm having an artists studio built in the garden. It's for my wife - she paints.

I can't make up my mind about the flooring. The building is 6M x 4M, is on a concrete base and will be 4x2 construction with builders paper & shiplap on the outside.

The options for the floor (on top of the concrete base) I have been considering are...

1. To lay 22mm T&G Chipboard on 50mm of Celotex. Then a covering of Lino. My only concern with this is that my wife wants some storage/work areas that are moveable - on wheels. I'm a bit worried they re going to be a bit heavy for this type of floor.

2. To have 75mm screed on 50mm of Celotex. Then paint with two coats of two part Epoxy paint.

Any other thoughts?

Thanks,
