    Permitted conservatory size


    How large can a conservatory be before planning permission is necessary? Does it vary for height, length, width or is it based on area alone?

    "Single storey extensions the rules are a lot more relaxed now pretty sure it’s up to 30m2 now without planning will still need building regs though but any decent builder comply with them anyways"

    "The possible size of your conservatory depends on the size of the property that you're extending. To build without the need for planning permission, a conservatory can't be any bigger than 50% of the area around the original house (including sheds and outbuildings)."
