OK, so what I'm missing is what is wrong with the plan you have posted?
You have the hob and the sink on the outside wall?
Is the issue that you think that the corner sink is too small?
300x400 is a bit, isn't it. Is this their Papillon PAX 652-E?Generally having the hob a long way from the sink is not a brilliant move, especially as it would be diagonally across the room and presumably the room is a thoroughfare? This could create a real danger.
Moving the hob to the other side of the room creates a major PITA, because you have to get the services over there and I agree, given the layout, you don't want a duct across at ceiling height. The only way that I can see that would make that half reasonable would be to run a flyover shelf across the top of the arch, as I mentioned earlier, effectively continuing the cornice line around the arch end of the room. You could use an extractor built into a top cupboard unit to complete the line, effectively stopping to the right of the window. The only thing is that that might make the room seem a bit narrow at that end. I wouldn't do that for either aesthetic, but more important safety reasons because of the hob location.
It seems to me that a better solution would be to keep the items roughly as you have them and do something to achieve a larger sink or a second one.
Can you put the washing machine anywhere else like the garage for example? Otherwise I wonder if there is a way for it to go the other side of the room on the oven wall?
Alternatively, could the washer go in the space the other side of the sink as you have it now where the plinth heater is shown?
This frees up 600mm under the window and you could put a second sink in there and a smaller one across the corner perhaps. It looks like you have about 300mm to play with between dishwasher and hob so you could perhaps move things around a bit in that respect.
The little vegetable sinks are a dead loss in practice - too small to do anything useful apart from deliver stuff to a waste disposer if you have one.
If you are tight on space, the best option is generally a double bowl sink You can drain things in it, stick a board on top for more space
- a lot more flexible than a drainer.
You might be able to fit in a double bowl or larger sink by moving the dishwasher closer to the hob and moving the washer as mentioned.
Corner sinks are deceptive - they appear to be large and make use of the space but are not as big as you think in practice.
