girlfriends house is late 1980's build & the part wall is light blocks
(can see in loft). Not sure if cavity (suspect not) but can hear just
about everything from next door through this. Next house will
definately be detached.

I have a pal with an '80s Barret's box terraced house (timber framed)
which although badly built in general has excellent sound insulation. They
appear to have two separate studding walls between them with double
thickness plasterboard and sound absorbing/insulation between them.
