I'm currently excavating my half cellar in a Sheffield terrace and am looking for some advice about a) council regs and b) using concrete to underpin the shallow foundation walls.
I'm at the stage where I need to decide whether to just leave it as it is or commit to a bigger and more costly project. I either need a good builder to give me a quote or advice, or someone with a good knowledge of foundations etc.
I'm pretty experienced at building work and haven't done anything daft yet, like digging below the level of the existing wall....
Any advice, suggestions welcome,
