Hi,

I am thinking of putting a conservatory on to the back of my house,
and am wondering how I am going to keep the use of my airbricks. The
house has a suspended floor, with 3 airbricks across the back wall of
the house. I want to put a base down for the conservatory, but this
will involve blocking two of the airbricks. Can I put some form of
ducting through the concreate base of the conservatory to enable air
to still pass through the airbricks, or do I need to build some form
of suspended floor for the conservatory, and place further airbricks
in the outer wall of the conservatory base ?

Hope this make sense to you...

Paul..

Either solution is acceptable.

I used the suspended floor solution, although this was mainly because it
would have been extremely difficult to get sufficient concrete in for a
conventional base, as I have a mid-terraced house with no rear access and
access through the house would have precluded wheelbarrows.

Run 100mm diameter pipes under the concrete slab to telescopic vents
in the external wall.

If yo have a suspended (timber) floor for the conservatory, there
should be at least 150mm clear air space between the underside of the
joists and the top of the concrete oversite. Your external ground
level should be no higher than your oversite, otherwise you run the
risk of water collecting under the floor.

When I did a simiar thing in my house we used 4 inch frain pipes to
duct the air bricks under the floor. You get into issues with cavity
trays and stuff in the cavity of the new wall.
