    Change of Use Permitted Development - Class M

    Under Part 3 of the GPDO - Change of Use

    Class M allows for

    (a) a change of use of a building from—

    iii) a mixed use combining use as a dwellinghouse with—

    (aa) a use as a betting office or pay day loan shop, or

    (bb) a use falling within either Class A1 (shops) or Class A2 (financial and professional services) of that Schedule

    to a use falling within Class C3 (dwellinghouses) of that Schedule.

    The main limitation is that the area changing use is less than 150sqm

    My question is this:
    if you have a shop with residential accommodation above (say 1 flat) can you under class M convert the flat into multiple units (say 2 flats) as long as the area of the flats are less than 150 sqm?

    does the situation change if the existing residential accommodation is self contained or non-self contained? in the example above if the starting position is that the flat above the shop can only be accessed though the shop and under PD rights you propose creating a new access and 2 flats?

    Since this Class of development requires prior approval it seems logical to seek approval for what you are proposing.
    The LPA will either accept that this falls within Class M or not.


      As you are creating additional dwellings I would suspect full planning permission is required.

        Hi all

        I just want to get some help on some planning issues. An architect mentioned that planning wasn’t required for an outbuilding and would come under permitted development. I had some friend of friend builders who helped with the build and lets say took it upon themselves to add water/toilet...

        I'd certainly expect this to sound the "beds in sheds rogue landlord" alarm with the council.

        Do you live in the main property? If so, why did you not notice the water supply being laid?

        If not, the beds in sheds alarm probably just increased in volume.

        1. What was the neighbours complaint ?
        2. Was it that you just had an outbuilding ?
        3. Was it that it was a few millimetres over size ?
        4. Was it that you had put a residential building up that was clearly residential, as it had water/toilet facilities AND a bathroom.
        Certainly not an outbuilding if it...

        I’m a first time poster on the site and couldn’t see anything that relates specifically to this topic, although various forums around the subject.

        I would like to do a loft conversion on our flat and the co-freehold owner has refused consent so we want to see if there is anything we...

        LondonResident has not logged on exactly a year ago tomorrow, so don't expect a reply.

        Any new questions on lofts should start a new thread, as not all leases and circumstances are the same.

        Did your co-freeholder give you any grounds for refusing consent? I am also a co-freeholder and have refused consent for a loft conversion which was requested by my other co-freeholders. My main ground for refusing is that I don't trust one of the co-freeholders - is that unreasonable?

        I know its a lousy plan, I was just hoping I could have some knowledge behind me in helping inform him that it is exactly that.

        Thanks for the info on planning time frames, this should steady him down.

        Hi all,

        My father-in-law is currently considering splitting his house into 2 flats, either to rent one to help with income during retirement or sell to release capital from his property.

        He is sadly suffering with Alzheimer's disease and doesn't really know the implications...

        by Charles Smith 007
        I have a planning permission to build some houses. The lower section of the road that they are on has no registered owners and our checks against the title deeds for the properties it goes past, the council land ownership and historic manorial ownerships have confirmed no record of ownership. The solicitor...

        The rebuttable legal presumption " ad medium filum viae" is that an owner with land adjoining a road owns up to the mid point of the road unless it is a public highway maintainable at the public expense when the Highway Authority will own the surface and a short distance below the surface....
