May buy a house in need of renovation / extension. I've never done this before and haven't got much idea where to start. So far my action plan reads - contact local planning office for general info; find someone to design it ( how? Is it better to hire an architect or do builders offer a design service) find a builder; Any advice welcome. I'd prefer not to go down this route but I need to have it as an option because there's not a lot on the market that doesn't need major work and we're beginning to get a bit more interest in "our lovely home"..
