I am in the process of building demolishing and rebuilding a small extension out the back of my semi D house. It is planning exempt. and I have employed engineers.
But it takes them an age to get back to me for this small project.
I have one area of concern. The party wall to my neighbors extension (both single story) is a cavity 100mm wall. both built at different times. my side is around 1950 and the neighbors 1991. My side is twisting away from the original house. therefor I want to demolish this too when I rebuild my extension.
We are using supergrund from aerobord for a raft foundation but this does not allow the ringbeam down the party wall side.
Is it possible to batten and slab and re insulate to the back of their side of the party wall or can anyone suggest other methods to read up while the engineers continue to do whatever they currently are doing
