I would be very grateful on any advice about this problem.
I have put down a reservation for a new-build semi house. It is still being built. Couple of days ago we went over to have a look at it, and noticed something.
The paving slabs outside the house appear to be too high - in one place, they are almost touching the air bricks. The damp-proof membrane presumably sits under the air brick.
There needs to be 150mm between the damp-proof membrane (i.e. bottom of air-brick) and the ground. However, because of the paving slabs, the "ground" has effectively come too high.
I spoke to the builders about this, and they said everything was fine! The house meets all the regulations because you are not meant to count the paving slab, and only the "real ground".
I have some photos:

I am going to speak to the Building Control department of the local council tomorrow, and hopefully the NHBC to see what they have to say.
Can anyone here offer any advice? Am I being stupid or missing something?!?!? Of course I could be completely wrong, and the DPM might be in a different place altogether!
Possible problem with dpc and path on new build!
