I know this is a bit of a 'how long is a piece of string ' question. But I am just trying to get a sense. We are offering on a run down house and trying to work out our offer. We don't need to extend externally. It would be removing a wall or 2 to combine kitchen and dining room and then refitting kitchen etc. Is it like 20 grand or 60 grand or more? I've simply no idea!
