Hello everyone... I'm new here and have a question about my new project:
I have attached a carport to my house, made entirely of concrete, with a terrace above it. The interior floor is paved with concrete pavers (underneath is mineral material and gravel). Now we want to convert this carport into a small hobby workshop/storage room. For this, we plan to glaze the entire front area and insulate the side walls (facing the ground/outside) as well as the ceiling.
Now our question is what to do about the paved floor, which so far has always been dry and level. We are considering installing an OSB board floor and thought about laying a relatively thick polyethylene (PE) sheet over the pavers, sealing it, and extending it under the exterior insulation. On top of the PE sheet, we would build a substructure with insulation in between (height?), followed by the OSB boards.
Would that be a feasible construction? The floor is level and there have been no settlements so far. Also, no particularly heavy machinery or objects will be placed inside. I would appreciate your answers and input.

To be honest, since the walls are concrete, I would tear out the paving, pour concrete, and either seal it or tile it, depending on what kind of work is going to be done.
OSB boards would remain exposed... possibly treated with oil. Concrete walls will be insulated from the inside. OSB with a substructure about 6 - 8 cm (2.4 - 3.1 inches) thick with insulation. It is intended to be a small, cozy hobby workshop for the father, where he can quietly listen to music and occasionally enjoy a beer while working.
