I cant think of many post war houses that don't have cavities. But
plenty of 30's style ones with solid walls exist.
There was a great drive to regulate everything in the post war labour

Lots of houses were built without cavities after the war, including many
thousands of system built ones like Smith's houses.
My house was built in 1928 with 11" cavities
...or rebuilt ones like mine (built 1949 to the original non-cavity

My house is circa 1922 with cavities although the gable ends are
without. Anyone know why the trend in those days, as I have been
told, was not to make gable ends with cavities?
The cavity is 11 inch - or the whole wall?
If you mean the cavity - did you ever lose any cats?
Youd get value for money getting them insulated.
Done that years ago... Maybe it is a 9" cavity. Recently a
builder was surprised to find the flooring screed was "coke"
fused by heat. The place was like a coal mine for weeks.
The reason for adopting cavity walls, contrary to what we were
always told at school (insulation) was to prevent damp penetration,
so there would be no particular reason to include a cavity on gable
walls - a damp patch in the loft wouldn't affect anything.
In my BCO patch, SW London, solid walls were the norm up to WW2,
which appalled a colleague who came from Portsmouth where they were
adopted much earlier due to the greater amount of driving rain.

No change there, then.
I suspect that it was less to do with regulation and more to do with
the realisation that with cavity walls you could use something other
than brick (e.g. breeze blocks) for the inner skin, all building
materials being in short supply after the war. All the pre-war cavity
wall houses I ever saw were brick/brick.
Cavity fill that and your house will be like toast and no heating bills.
A good thing Matt. They haven't gone far enough. You need regulation
The cavities were to stop damp. The skill levels were not high, so putting
two walls reduced the likelihood of a damp claim
Poor brickie skills after WW1. Many were trained quickly. They failed in
the detail aspects around doors and windows. A whole blank wall was fine
And very low heating bills. Make the house air tight and near an eco house.
