Bump...

I have your setup #1 and it works well, we do drip a bit of water on the floor between sink and dishwasher, but you learn not to!! Also it gives a full clear bench on the peninsular for eating, setting out, or working or whatever. Your kitchen is slightly narrower, from memory ours is 1.6M not 1.3 as you have yours, Our peninsular has a circular end which has actually proved very beneficial for sitting round, and seats up to 5, meaning you are not sitting in a long line, but facing each other round the end, - I love it, it is a real gathering point.

The outer side of the peninsular curves in to the centre, then flows out to make the circular ending, so its not protruding into the kitchen but into the other side, sorry I don't think I can add a sketch to this.

you could move your fridge down near the pantry to give less congestion, its not that far to walk and near your other supplies (pantry) I'm not sure what you have that little bench area as?

The little bench area is for the toaster and jug - it means the youth can get breakfast and snacks without having to come into the main part of the kitchen. There's also a window out to a courtyard about where the fridge would go if it were on that wall; and the bench is only 450mm deep there, so not really deep enough for a fridge - making it deeper would shorten the rest of the kitchen and the peninsula.

Thanks Nicola and Marg, that's two votes for the sink in the window, both based on experience, which seems solidly conclusive.
And I didn't think of using it as cutting out table, that's an important point - a much better height than the kitchen table too I'd imagine?

Hi Lucy

My vote is also for under the window. Who spends heaps of time at the sink?

I agree with everything Nicola said re entertaining.

Good Luck.
