Ventilating existing timber floor

[sintra]

Hi,

I wonder if anybody could point me in the right direction on this one please.

What would be the best way to ventilate an existing suspended timber floor when building a new concrete slab for an extension next to it ?

Cheers

If your covering over existing air bricks your ment to pipe them out beyond the extension, but most building inspectors will allow for additional air bricks in adjacent walls.. best ask BC
