I had a teeny galley kitchen in my London flat. I could cook more easily in that, than my current kitchen, which is 4 times the size but layout like a bag of shite and tons of space wasted.
It's probably 3 times the size of that kitchen but that one has double the usable counter tops for actual prepping / working etc.
It's certainly usable in the short term, unless you're running a small catering firm.
Store the crockery etc in the dining room.
