speaking of a million years old. the house i moved into a few years ago has this weird concrete stump thing in the cupboard under the stairs... any kind of builder/maintenance type people know what this thing could be?im willing to take a sledge hammer to it to get rid of it. but i fear that something bad may happen if i do... i've asked the previous owner about it and he doesn't know what it is either...take a look folks. the pic is on its side btw...

Urban_Tribesman said:Hey Cookie. Is the air brick directly in line with this lump inside? If so, air bricks are for ventilation, not flooding, and it would suggest something is being ventilated and this 'stump' is it turning down to go below ground level.
Is the floor solid or suspended? ( does it sound solid or hollow when you stamp on it?) air bricks are usually associated with suspended floors. If not ventilated, these will decay and rot if the moisture level gets too high.
Does the house have a cellar? Difficult to tell for sure without seeing the room in context with the rest of the house.
I am sure Appy61 will have a view but more pics would help. How old is the house? The pic suggests 1930's or before?

Urban_Tribesman said:Sounds like the external ground level is too high allowing dampness outside to penetrate the wall which, I would guess, is a solid wall not a cavity. That would be the cause of your efflorescence.
Do you, by any chance, go down a step into the 'office'? I wonder if the room once had a raised timber floor that has been removed in the past, resulting in this stump to cover the air brick.
I still think the most likely reason for the 'stump' is to turn the air flow from the air brick down to a lower level, hence the question about the cellar.
Can you see through the air brick from outside? Use a torch to see if you can see anything. I doubt there is a water or gas main as Satori has suggested as these would be obvious externally. Do you even have gas? Where do these (gas/water) come into the house? If somewhere else, then they won't be here as well.
Ideally, your external ground level will be 150mm below the internal floor level to prevent the ingress of damp. People mistakenly raise external levels all the time and cause damp issues inside, so worth looking at.
Have you got access to some net curtain wire? If so, get 3 or 4 foot and fish it through the air brick and see if it keeps going in, which would suggest it is passing down to a lower level.
Still,waiting for @Appy61 to comment. Where are you in the country BTW?
