I initially thought halls together would be preferable, due to TV noise
etc. But I actually find it a lot more disconcerting to be having a
quiet bath when a trumpet-nosed neighbour next door can be heard
blowing his nose. I guess with small bathrooms, you are often closer to
the party wall. Also, banging of kitchen cabinets travels easily
through a solid party wall. An front doors / stairs also tend to be
loud. If I had a large house where rooms could shrink, I would be
tempted to build a cavity wall onto my side and move all the joists
etc. Or better still, win the lottery and buy a detached house.
Any experiences or preferences?

I've got 9" brick party wall, with hall/stairs/kitchen/bedroom1
mirrored. The only sounds I hear through the wall are creeking
staircase (which was more noticable with previous occupants)
and someone stirring a mug of coffee on the kitchen worktop
with a teaspoon.
