Hello. I have a back-to-back red brick mid terrace house in the UK.
There is a
large crack in an internal wall on the 2nd floor. The wall between the
bathroom and the bedroom. The crack runs diagonally up in a step
pattern from
the bottom corner where the wall joins the external wall. The crack
is visible
on both sides of the wall. It is no more than 5mm wide at its widest
parts. I
cants see signs of cracks on the walls below. Can this be due to the
support
of the 2nd floor weakening? Or is the wall bowing. Please can anyone
help me
work out what is happening and what might need doing to fix it please

You need professional advice from a Building Surveyor.
Contact your Buildings Insurance Company.


'Terraced back-to-back'

This this mean potentially 5 party wall agreements to fix this ?.
(2 on one side, three on the back).

I think only the two immediately adjacent party walls are relevant.

The way I remember terraced back to back there was always a high walled
paved back yard containing the outside loo, coal bunker and sometimes a
token garden about one flagstone in size. Rows separated by a narrow
alleyways where the bins lived at the backs and a road at the front.
