Hi,
I have now drilled through and it is a 250mm difference between the floor heights. DPM then 125mm of insulation then 125mm of concrete?
Thoughts are much appreciated.

Morning All,
I am converting my attached garage, the house is 20 years old. My semi-retired builder has suggested a wood floor, two sleeper walls at each side then two in between giving a span of about 4ft. The 4x2 joists and 22mm chipboard of the top.
My questions are is this the best...
