What changes by area
In the older core, Victorian and Edwardian semis and row houses often have shallow basements, shared walls and tight lanes, so neighbouring foundations and equipment access shape the plan.
Further out, post-war bungalows and detached houses often have more room around the foundation, which can simplify access, although soil and groundwater still need checking.
Ravine lots and low-lying areas can have higher water tables, which is why drainage and waterproofing are planned together with the lowering.
