air brick / conservatory

[ricky101]

Hi,

Because the land slopes down from the back of the bungalow, errecting a conservatory in the typical manner would probably not meet planning regs as the ground level to ridge would be over 11ft, plus it would look really odd being so elevated.

The back wall brickwork DPC is about 5ft above ground level, so the obvious thing would be be to fit a 8ft high conservatory just below the back wall window sills which are all on the same level.
However that would mean the four air bricks would also be covered and know it would not be correct to block them off.

We would also like to use the conservatory partly as a greenhouse so again cannot see it would be good for its sometimes moist air going back though the air brick to the suspended timber floor in the house.

Is there a 'proper' way around this airbrick problem eg truncking / ducting of some form ?

Yes that is essentially what is done. But normally the ducting would be straight through. In your case it would have to be stepped and although this should allow your existing floor to have cross ventilation, I have never seen it done like that and would speak to a building control officer for an opinion.

Its quite normal to have staggered ducting of airbricks, usually where you need to vent a suspended floor under a solid floor. You could use some variant of that.
