What other provision for venting the underfloor void is there?

Usually they're designed with cross ventilation to ensure rot doesn't
occur in the floor joists.

There are too few airbricks i fear. but absolutely no sign of rot -
timbers completely sound. (we have a 2-3 foot crawl space that I have
investigated. There used to be 4. Two each side of the 10m square
bungalow. One has now been blocked up because of an extention. I'm
looking into getting another two added along a third side of the
bungalow, but these will need to go down first as the ground level is
high (but not over the DPC)

Another thought was to put some electric fans under the floor for
active ventilation - any thoughts on this idea would also be welcome
(I'm contemplating this because we have just found mould on some of
the kids toys and on the underside of our matress - urgen action is
required!)

Cheers for your input.
