Just been reading this thread and I was really hoping that the OP or anyone else in a similar position was still around to offer us advice.
We bought a house where the double garage (joined via a small hallway next to our kitchen, so no separate entrance) was converted into an annexe. The previous occupants had the garage converted to accommodate an elderly relative, but unfortunately the relative died before it was completed I believe. When we bought it they were using the 'kitchen' as a utility room, extra bathroom (house has one other bathroom),extra living room and home office.
Now that we have bought the property the VOA have written to us to say the annexe is to be rebanded to have its own council tax band. When we phoned to query this they offered to come round to have a look and are coming next week.
As I see it the utility room is just that. It is tiny, has a sink and space for a washing mc, a drier and an undersink cupboard. It has no cooking facilities, although I suppose that you could squeeze an electric oven under the counter where the washing mc or drier are. Fitting a hob would be very difficult though. Technically i suppose you could squeeze it in next to the sink but would have to remove an electrical socket behind it, or you could put it in front of the window which is the only ventilation point. I really find it hard to believe it could be classed as a kitchen though and it has never been used as one. There's no gas supply either.
We are not allowed to rent the annexe out separately under the planning permission rules and to be honest would never consider it as it is part of our home and is used daily.
mylovelymonster could I ask exactly how you convinced the VOA to reband your property as one? Does anyone else have any idea how we can make the VOA see that the whole thing is just to provide us with extra living space?
Thanks for reading and I hope someone can help.
