does anyone know of a good on-line site giving details of how to
construct cavity walls

I guess you are asking how to build a brick wall, a cavity wall, is
just 2 walls, with a gap between. and some ties joining them together.
The two walls do not need to be of the same material, mine, for
example are stone & block.

The ties give extra strength for "wind loading", the BCO made me cut
all the ties out where the wall was not gonna get any wind (cause it
was below ground).
