Air brick, solid wall goes 33cm into the house, ground floor, concrete floor, ideas why?

The 9” square airbrick looks like modern clay type to me, post war at a guess.




The airbrick is below DPC level, how does that equate to the internal floor level?


Also do you have a fireplace in the room? If so is there an air vent in it?

Floor is solid floor screed or concrete, tiled on top

May help or not, but this was originally a stables many many years ago

Probably a suspended floor converted to concrete and the air brick wasn't removed.

The OP, suggest it was originally a stable. It would be a solid floor for the weight of a horse, if true.

Is the internal floor higher than the DPC level?

So it would’ve had a stone floor of some sort.

Airbrick isn’t likely to be an original feature.

The airbrick where it is with ground level coming across the front of it, makes it vulnerable to water going in

OP,
The air brick - the DPC - & the common bricks are all modern, definitely not 1780 - what the pic shows looks more like 1980?
Why not lower the ground level by about 100mm?
After removing the plasterboard then why not post some pics?
If the air brick is a vent duct to the room beyond then the duct must come up & show itself in the room beyond?

It's too cold to remove the rad on the inside, to then cut into plasterboard, so that will need to wait until April time. But yes will do.

I have the architects set of blue prints and work docs from 1971 as we're given to me by estate owners on moving in, when they converted the stables doesn't mention this area. Next door (all houses listed) found at 15m deep void below their kitchen (was parallel to the well in their garden), so who knows might be that.

Thanks all, I think will look later.

If you meant remove on outside.. 100mm, I did have building control here about a year ago wanting to see how far down the building went for a different face of the building. We went down 9 courses of bricks below ground before guy said stop as we could not get to the foundation start point which he said would be below the bricks. Mystery maybe a cellar. Anyway that camera endoscope thing ordered so once arrives I'll take some photos and upload.

OP,
Yes, on the outside.
