we're thinking of swapping our kitchen & lounge over and wonder how much it could cost & where to start. I guess we can re-use all the units as they're fine but am thinking the granite work surface might need to change as it has been cut to fit the kitchen as it is and I wonder if it might not fit in a new layout. We'd need to factor in new wall tiles, plus flooring, lighting, plumbing. Is there something else I haven't thought of? There is gas in both rooms but guess it'll need piping adding to it maybe. I don't really know where to start...do I call a builder or an architect? Would also like bi-folding doors in the new kitchen and again have no idea how much these cost or how long it would take to do. Any tips, advice, recommendations please!!!
