I'm installing a timber floor in my garage conversion.
I need to raise the floor 200mm to existing, so im going to lay 175mm joists straight onto floor with DPM and 22mm chipboard with 100mm celotex between joists.
When I thought it was originally going to be suspended, I was going to fit wall plates with thunderbolts and joist hangers. As they now will be sitting directly on floor, will it be suitable to install the wall plates with a few less thunderbolts and just spike the joists to it?
Also, should I lap the DPM up above the floor and trim back down, this will still be above original damp course of brickwork.
I will also install an airbrick in the new front wall to allow ventilation in floor.
Regards
Jack
