Right now I have a large and stylish open kitchen but there are times where I miss having a galley kitchen, where I could stand in one place and reach everything I needed - pots and pans hanging from the ceiling, knives and accessories on magnetic racks on the walls, fridge contents reachable while standing at the stove... somehow it even had enough prep space.
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.
I have a large open plan kitchen with one counter surrounded by hanging pots and pans, knives on a magnetic wall mount, all chopping boards stored vertically in racks and most of the condiments on a wall rack or in the drawers
