Air Brick Query in Bungalow Small Side Extension All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

[French Chris]

Hi guys,

I hope someone can help.

Just about to move into a 1960´s bungalow with a 1980's small side extension for an en-suite which replaced the original path between house and garage. The extension/garage roof is flat felt.

As you can see from the photo, on the rear return wall is a square ventilation brick. Not sure why it is this size rather than the usual brick sized ones, nor why it is so high.

I want to install a bathroom ventilator fan and the best place would be just where this air brick is !

Can anyone tell me if this can be replaced with a smaller one lower down and perhaps why it was put in this position in the first place.

Thanks in advance for your opinions.

Chris

Hi frenchchris.
It was quite normal in the 60s to provide ventilation using a 9x9 airbrick - the room it serves was probably a bathroom or toilet. Just fit an extractor in its place, don’t bother to fit a replacement airbrick.
