Broad topic I know:
But I am going to post a picture of our layout so far. The island will extend a bit longer in front of the fridge/freezer (elux), and there will be a prep sink it the island (but where?)... But otherwise I think it will be about like this. The pantry is 36" pull out next to the fridge and there will be additional pantry space in the laundry room.
The range is a 36" range.

Does it look ok?
I am really not sure about the size of the range, and what type of microwave or speed oven we will need.
I currently use my toaster oven about 90% of the time, and don't want to have a toaster oven on the counter in this house. So I am wondering if I am making a mistake with that large of an oven.
The problem is that a 30" range would look tiny in this kitchen, and if I do a 36" cooktop then I would need to do wall ovens and I don't know where we would put them.
We can put a speed oven or mw in the island undercounter...

Any opinions or ideas for us? The windows on the cooktop wall are not there currently and so could be reconfigured.
