Dave you are slightly incorrect. If you are running a business from home do not designate any specific room as your 'office' or you run into trouble from the tax man and Capital Gains when you come to sell. You do not need to do any building work to fall foul of 'change of use.' Home to commercial premise is enough. Also insurance if the general public are coming on to your property.
Sorry Chloe, I don't want to dissuade you, I think it's a great idea. Good Luck.
