Hi, As Ian has said, you do have a thing called permitted development, you architect should be able to help you there. You will also have to check that you are not to close to a boundary. Permitted development does not apply if you live in a listed building or in a designated area e.g. National park or world heritage site etc. if you google planning portal there is all the information you need on there. Proper plans and building regs will still apply though. Good luck Ian.
