If you cook with a partner, a kitchen with a wide enough aisle so that one can open a dishwasher and also open a cabinet on the opposite side makes life so much easier, since it means it is also wide enough for 2 people to move past each other easily.

Big tub sink on one side, range on the opposite side of aisle, and at least 3ft/1m of countertop space on both sides of each those is my ideal. One side of the sink will have a dish rack, leaving 3 sides. That means 3 available spaces for prep, eventually turning into 2 as dirty kitchenware piles up next to the sink.
