Can anyone tell me if I need full planning permission to convert an already partially converted, attached garage to a downstairs reception room? (A surveyor recently suggested we could do this for around £5,000)
The previous owners informally used it as a 'den' and have an old (currently not working) gas fire and what I think is hardboard covering walls, carpet tiles on floor etc and a skylight, plus bed platform accessed by ladder. As far as I know, they never got planning permission and so the room doesn't count as 'residential purposes' - only as 'storage'/garage. But their teenage children used to live in it as an annexe, some years ago (It has an internal door that leads onto a hallway, shower/toilet/ cloakroom area in the house.)
It'd need fitting out properly to make it liveable - especially in the winter and possibly need a window at the front too. DCs currently use it to store toys/ summer playroom.
I know nothing about planning permission but I do know that the neighbours (not attached) on that side of our property are very difficult and we've not been on speaking terms for the last 2 years.
I guess I'm wondering about the feasibility of turning this room into a proper reception room but not at all wanting to face hassle from neighbours, IF that might be the case (although we happily accepted their extension on that side a few yrs ago, with no complaint).
Is it a major deal to change an attached garage into a reception room? What kind of planning permission do we need and what else should we be considering?
