Paving above DPC?

[T5GRF]

We have been talking to landscaping companies regarding a new patio. We would like to raise the level of our new patio to bring it above DPC to keep the floor level of our new extension the same height as the hard landscaping outside. We would look to install a French drain or Aco drain to carry water away from the wall but I understand that covering over air bricks is not a good idea so will need to find a solution to keeping the air bricks free of obstruction.
I have asked 3 landscaping companies to quote for the job. I got a mixed response from them regarding raising the level of the paving above DPC level and in relation to drainage and keeping the air bricks open.
Is it just a bad idea to raise the level of the patio up in terms of damp issues even if we use a French drain and have the patio falling away from the house? If we do put a French or Aco drain in, what is the best way of keeping the air bricks un obstructed?

Thanks for the advice. It looks like a no then however, so many projects I see on line seem to adopt the approach if raising the height of the paving to match the inside floor height, I just wonder how they achieve this without damp problems!
