I'd like to look at options / feasibility / costs for knocking through a (supporting) wall, adding a back door and then a new kitchen in the resulting space.
Do I need an architect? A builder? A specialist kitchen design company? Ikea kitchen design programme??? I'm clueless!!!
Obviously don't want to waste money on services I don't need and happy to investigate the DIY kitchens plus kitchen fitter option I've read about on here. But not sure if the building work will knock that idea on the head??
How can I get a kitchen design before the space I want actual exists?? We need to get costs before we start knocking walls down 
I know this will be bigger, more expensive and take much longer than I think it will so am asking for your wisdom before I even start.
