So the concrete got poured yesterday and it is sufficiently hard enough for us to start building.
We have used pressure treated 4x3 for the perimeter and treated 4x2 for the joists.
All this is suspended off the floor with the steel shoes, 100x50x8mm, which are sat on the M24 threaded bar. We used a laser to level these put a spirit level will do the same job.
100mm foil backed rigid insulation is then fit using roofing battens to support,
22mm Egger Protect is then fit as a floor and screwed with 60mm screws and glued at all joints with polyurethane glue.
Thanks for watching
