The microwave. It's an essential everyday appliance for many people despite its countertop-hogging footprint (a serious consideration if you cook in a small kitchen, and the reason some eschew the microwave altogether). To save on flat surface space, I've seen microwaves installed above the stove or in an island, but in a cupboard? It's new to me, and I like it!
This kitchen, though grand-looking with its marble counters and white and silver color palette, is actually quite small. So the owner, Kelly Giesen, installed a small microwave in one of her cupboards, and looped the electrical cord through to a power outlet. Smart!
