Hello. We would really like to air bnb our annexe. It was built in the 90s as a 1 bedroom, 1 living area, kitchen and bathroom. Own front entrance and interconnecting door with main house in coridoor on first floor. Building permission stated it could not be rented out. When we moved in, we removed the kitchen and turned into an office/ utility area, to avoid paying 2 council tax bands. We are considering reinstalling kitchen, to air bnb. We have contacted planning consultant to apply to council for change of use. Has anyone else had any experience in this area? What was your outcome? We are also unsure if we could rent it under the rent a room relief and pay council tax, or go via business rates route, again does anyone have any experience or advice? Sorry for long question. Many Thanks
