Air brick at paving level

Hi folks,

I own the flat in the picture below (left hand one). You can just about see there there is a small air brick built into the concrete step into the building.

Inside this there's a suspended timber floor leading immediately to the stairs (it's an upstairs flat).

It's damp in there, I reckon because this air brick thing is flush with the pavement. I guess the council raised the pavement at some point. The other properties all have the original stone step with no air brick.

Any ideas what I should do to ventilate the underside of the floor if I fill in the air brick? Or should I even bother (it's only 1sqm)? There's no room for another air brick as the floor level is the same as the outside ground level.

Should I just install an internal vent cover into the floor so it breathes into the main building?
