Very easy to bring the level down (if you feel this is necessary; but
that's a different story) by increasing the ventilation. What are the
current ventilaltion arrangements for each room?


Normal BCO resolution in cases like this is to insist on suspended
floors with underfloor vents I believe.

Its a bit of a pain to mod an existing house.
