A kitchen can have a simple phone and message area.
Early kitchen researchers defined three pri-mary kitchen work centers reflecting three different sorts of kitchen work: cleanup, mixing, and cooking. The cleanup center includes the sink, a place to stack dirty dishes, probably a place for a drainboard, cleaning supplies, and often storage for everyday dishes. Today, the cleanup center would usually include a dishwasher. A trash can is essential, and the countertop should be waterproof or water-resistant. A cleanup center may also be a place for good preliminary recycling. The mix center (or food-preparation center) should be organized around the premier work counter, with easy access to favorite knives, utensils, bowls, and small appliances, as well as to the most frequently used supplies, such as oil, salt, flour, and such. Sometimes butcher block is used here, though many people prefer movable chopping boards. The cooking center includes the stove, another counter, a heatproof place to set down hot dishes, and tools and supplies used primarily at the stove, such as pots, pans, lids, spatulas, pot holders, and perhaps spices.
Today we cook very differently than early researchers did, but these three basic and relatively distinct work areas are still helpful design building blocks. Many designers rightly add a fourth function, the serving center, which is often near the table. It has a place to set hot pans, and it houses serving dishes, perhaps the good tableware, and napkins. Many cooks also define other centers for inclusion, particularly a baking center. A message center might be as simple as a wall phone with a pad of paper, but it could be large enough to include a desk with a computer for doing homework and paying bills. Your kitchen might be large enough to include a recycling center, where newspaper, bottles, and other recyclables can be organized on their way out of the house. As I survey and evaluate any kitchen layout, locating the basic work centers on the plan, I have a specific range of dimensions in mind.
