Even if you’re more of a maximalist than a minimalist, the fewer appliances you have on display, the nicer your kitchen will feel. Can you replace a kettle with a Quooker hot water tap? Can you use the grill in your stove rather than a toaster, or can the toaster be kept in a cabinet? If you have the room in your cabinets, ideally the appliances that aren’t in constant use will be shut away, like blenders and food processors, and if you can find a way to have your microwave integrated into the cabinetry, it’s absolutely worth doing.
But if there’s an appliance that you particularly like the look of, like an artisan coffee machine or mixer, then keep them on your worktop and let them stand proud. They’ll look all the better for it with the other appliance distractions out of sight.
