Semi detached Party walls

[omph]

Does anyone know about the building standards with regards to semi detached party walls ? Were all properties designed to have cavity walls ? I have a 1950s no fines property so I am guessing the party wall is of a similar make up, but I'm not sure whether cavities were ever installed in no-fines party walls, or whether that was even possible.

Probably solid, one brick thick (215mm) walls, of that period.

[Wimpey] no-fines was a system were all the wall panels were of solid concrete, the party wall typically 250mm.

Just drilled into it, its not a no-fines. Drilled material is light grey so looks like a standard block thankfully. Weirdly enough, I have gone in about 2.5 inches and can feel a cold breeze?? This is ground floor of a 2 storey building.

Any complaint, from next door, about a new hole in their wall

Could be hollow clinker blocks.

In my quest to discover the underlying issue I drilled another hole, albeit smaller (20mm) and that too had air emanating from it.

Could be hollow clinker blocks.

Not sure, it seems to be dense for all the holes drilled. I can't see or feel any voids when poking around.

If this is an ex- council house, get in touch with the council's housing department and they will tell you what system it is and the construction.

I was once chasing a wall in an ex council flat ,20mm max when I saw the back of tiles in next doors flat .
