cracking.

Hi, We are trying to buy a 3 bed mid terraced house that was built in the late 1800’s but the rear extension is on its own as the house next door was built later. As it’s an area with lots of subsidence - south London. We only got a valuation completed as we didn’t want to pay £’S for a survey...

I have a wall that is breeze but has thermalites built onto the end, what mesh (am assuming galv) arrangement might be necessary at the transition between the two to prevent cracking? Do I need special fixings for mesh? Thank you.
