The traditional work triangle that separates the sink, range and refrigerator has evolved into a more practical "work zone" concept.

"We have gone from the traditional kitchen, where one person prepared meals to a multi-purpose room and a multiple-cook room, and this evolution has changed us from looking at one work triangle to multiple triangles, or 'zones,'" says Mary Jo Peterson, principal, Mary Jo Peterson Inc. "With that in mind, we have to increase clearances and look at adding comfortable spaces in the kitchen."

Still, these tried-and-true kitchen layouts still apply to today's lifestyles—with modifications.

Basic Kitchen Layout Types

One-wall. Originally called the "Pullman kitchen," the one-wall kitchen layout is generally found in studio or loft spaces because it’s the ultimate space saver. Cabinets and appliances are fixed on a single wall. Most modern designs also include an island, which evolves the space into a sort of Galley style with a walk-through corridor.

Galley. This efficient, “lean” layout is ideal for smaller spaces and one-cook kitchens. The galley kitchen, also called a walk-through kitchen, is characterized by two walls opposite of each other—or two parallel countertops with a walkway in between them. Galleys make the best use of every square inch of space, and there are no troublesome corner cabinets to configure, which can add to a cabinetry budget. Download a sample floorplan.

L-Shape. An L-shaped kitchen solves the problem of maximizing corner space, and it’s a smart design for small and medium sized kitchens. The versatile L-shaped kitchen consists of countertops on two adjoining walls that are perpendicular, forming an L. The “legs” of the L can be as long as you want, though keeping them less than 12 to 15 feet will allow you to efficiently use the space.

With an L-shaped layout, you’ll eliminate traffic: The kitchen will not become a thoroughfare because it’s just not logistically possible. Plus, you can easily add a dining space and multiple work zones to this layout. However, avoid this layout if your kitchen is large and can support other configurations, such as adding an island, or if multiple cooks will be using the space. Download a sample floorplan.
