Right plan...can you increase distance between island and range? can you cut back pantry allotment and increase counter to right of range....the island could be 39 in deep instead of 48 in that you show. consider that. The island plan with some fine tuning is my vote.

I think that is called a "G"! I like it better but might shorten the peninsula a bit to open up the bottleneck a bit.

The one on the left is far more functional and versatile.

I prefer the L-shape for the way I like to cook. Fridge, counter space for landing, sink for washing, counter for chopping then stove for cooking. I'd like to have additional counter space to the right of the range for plating or for letting food rest. But the island can serve that purpose. The island can also be used as additional prep space if you have a helper.

The U-shape is good, too, but the draw back for me would be having the fridge across the room from my sink. I'm all about efficiency for cooking and I think those added steps might interrupt my groove.

Would what the people sitting at the island look at make any difference to you? Or if you are working at the island would one be a better view advantage over the other and be something to consider, too?
