I have been refused planning by an Bord Pleanala to build on a site which currently has a derelict cottage and derelict mobile home on it. I'm now considering doing up the cottage, extending it and replacing the mobile home with a new one. I realise that I will most likely have to apply for planning to extend the cottage as the extension will be quite large but I don't know what I have to do to replace the mobile home. Is it okay just to remove the old one and install the new one or do I require some sort of licence to do this? I need to live in this while the cottage is being constructed. Also, if anyone has any experience with the planning authorities with regard to doing up an old derelict building I'd like some feedback. How much of the existing building will I have to retain? More importantly, will I be allowed to do up the cottage seeing as it has been unoccupied for a number of years? Any information would be much appreciated. Thanks.
