The design layout could do with changing if this is a two chef kitchen - as currently hob and sink share same floor standing space, the DW when open blocks the walkway - oven is danger to anyone opening door... The FF is not what you want - the list goes on !!! Difficult to help further with no sizes - I could guess from the doors - but no head on shot of the right wall so a bit tricky - this could be a 'very quick' job as a sketch consult on an hourly rate, if you want pro help - drop me an email ! If you were thinking of using ikea for example - you could buy and have installed the carcase's, drawers, worktop, sink and appliances and then add the facia fronts as and when you have spare cash - this would stretch your money a little further ... £4k is still a lot of money - invest it wisely !

I would have said integrated 6 months ago, I have always has integrated appliances. My main concern with the American fridge freezer was the lack of storage on the slimmer freezer side. And the depth that they protrude from a standard kitchen. Then I discovered Fisher & Paykel. I have opted for the American look with 2x fridge freezer side by side. Using their connection kit and surround. I couldn't be happier.

I think you're rather stuck on where to put a fridge freezer now the kitchen is done because it would need to go on the end of the run because of the height. I guess you could put it in the dining area along with a couple of larder units to make it one long continuous run if you're opting for a smaller table although I do like how it currently is. Regarding corners I would always plan a 900 L shaped base in each corner because you can then open each door offering you full and easy access to the whole area. Much cheaper than installing chromeworks in a cupboard for a decent brand.
