RSP,

No I have not heard of this idea, and you may want to get some engineering advice before you do this, as it would considerably weaken the slab. Keep in mind your obligations under section 116 of the act, which would require you to submit engineering certification regarding these proposed works.

I have seen an owner install a false floor within their apartment to accommodate the plumbing under the floor, but I understand that there is a minimum floor to ceiling height defined in the building code, so this could be an issue.
