    "Re-routing your drainage system because of foul smells from a sewer it’s quite straight forward, should include this on the plans of the extension!"

    "You need to comply with building regs and get them to inspect and approve any work done. Also, the sewerage utility will need to be informed in writing.

    "The sewer pipes or the sewer lid would have to be moved out before the footings and extension can be done but that can cost a bit extra to do so but new pipework would have to replaced and new put in and make sure they put pea shingle in before a ballast mix can be poured to bring up to the existing level of the old floor."
