Typical wall thickness

[ScottishGasMan]

Might be a "how long is a piece of sting question"

But in a semidetached property, what would the typical dividing wall between the two property thickness be?

Houses are 1900-1915 Sandstone bungalows, Roughly 400mm sandstone round the perimeter but brick/block in between the two property's where the chimney breasts are.

Just doing a few drawings and heat loss calcs and no idea if its single/double/other brick.

Internal walls are mostly 15cm thick including the old plaster on each side.

Scottish domestic construction differs from English, but generally the party walls - if of brick - are 9" (215) thick. (Though plenty of Victorian houses down here have half-brick party walls).

The vast majority of brick buildings I've dealt with had party walls 225mm with a few that were single leaf but very rare.
Stone buildings I dealt with were generally 450-600mm thick with corresponding party walls, the thickness gave you a rough indication of age, 450 -500mm approx 100-120 years old, 500-550mm approx 120-150 years 550mm+ 150 +years old.

If you're just worried about heat loss, assuming the other bungalow is heated then it should be roughly zero through that wall, no matter how thick.
