thanks for your replies:
i just have one query: how is it a change of use to convert an attic? the house is a domestic dwelling and will still be a domestic dwelling if we go ahead? the change of use regards, using the house for the means of running a business etc. surely not using space that is already there for a means by which the rest of the house already serves.
Could you please explain how its a change of use? at present it has none.
Also if this is the case,
would it even be worth converting the attic?? how much would it cost to be able to get permission.
