Hi the house is approx 100 years old and in the lounge diner it has a lower floor by 2 inches that the rest of the house. I think this was just so it could be insulated with wooden floor boards as it only has one living room downstairs.
The old structure was concrete floor (rough) and a little damp then bits of slate laid with mortar on top of them then wooden bearers on top of this with floor boards over.
There was a lot of wood worm and rot so the whole structure has been removed and I have fixed the source of the water and treated the area with a biocide.
My question is what to replace with bearing in mind I want to keep the depth approx the same to meet with the kitchen and hall concrete floors which are just over two inches higher.
My initial thought was a DPM sheet but not sure on what thickness or weight then build a timber structure of 50by50 again or a bit wider, I'm guessing that would just sit on the sheet and not be screwed through it, maybe some mortar on top of the sheet to level the new floor bearers or is there a better way to do it, then 22mm P5 chipboard flooring on top.
Any views/advice greatly appreciated
