A kitchen working triangle is a design strategy that says that the three main work areas should form a triangle between 1) the sink (and dishwasher), 2 ) the stove/oven, and 3) the refrigerator.
The most basic kitchen layout is a one-wall kitchen. This simple kitchen floor plan puts all of the countertops, cabinetry, and appliances on a single wall.
This design helps keep traffic out of the kitchen, forms a natural triangle work zone, and gives you enough space for a dining table and chairs (or an island).
