Air bricks being blocked up? Why?

Surely, by 1935, all houses were being built with cavity walls?

I think i read recently that 1935 was the year that they started putting them in all houses.

Just like i think it's cruise control that came in on my car on the 51 plate...except my car doesn't have it, but the 02 plate does.

I've done that much reading lately that it all merges into one. I think it was cavity walling that i read about that.

Seems like it became standard during the 20s (mine was built 1925) and nearly all houses were being built with them by 1930. That doesn't prove anything either way about yours, obviously, but it would indicate it was unusual if it was built without a cavity.

Interesting info. Thanks. Perhaps the house does then, i don't know.

Out of interest, how would i know?

Our house, built in 1930, has cavity wall insulation and also has one of these air bricks, up high, on the outside wall of the smallest upstairs bedroom. I have it closed off on the inside.

I always wondered why it had been put there. That room never would have had a fireplace. Could it be that it was built to have a gas heater instead and that would have been safety ventilation? The room is directly above the hall and it would have been easy to route the gas main up to it.
