Recently started renovating kitchen diner in 1870's house. In kitchen diner there is a vent around 1ft below the ceiling which presumably once was to an air brick. This has been bricked up on the outside wall however in the past only one brick thick, internally there is still the vent cover behind which is a void to the single brick.
No damp issues etc. are visible in this room, lots of windows with trickle vents etc. allowing for air flow with condensing boiling (I presume this vent was once for an older boiler). We were planning on filling and plastering this hole, however is this advisable? Would we be better fitting a nice vent internally should we need to open this up in the future if probably arise? Any suggestions?
