I am hoping to get away with a 1M deep strip foundation but there is a hedge on one side so I assume I will need to go a bit deeper on this side.
The bigger issue, though, is that a sewer pipe run under where the garage is to be built and this will likely clash with the foundation concrete. I would rather not move the sewer pipe. What are my options?
Can I run the foundation concrete round the pipe if I somehow line the outside of the pipe so as to leave a gap for the pipe to move within the concrete? Would this be allowed and would this work? I know I have to get the building inspector involved at some stage but I want to do a bit of research first.
If this is not possible then can I build a raft foundation slab instead and build the garage in this slab?
Or what other options do I have?
