Pros: Concrete countertops are durable, resistant to heat, and can be less expensive than natural stone, especially when completed as a DIY project. Cons: Concrete must be sealed before being used; otherwise, its porous nature means that it will stain very easily.

Guess used inexpensive graded pine plywood so that he would get heavy grain patterns on the surfaces. One of the main goals in the kitchen was simplicity. To that end, he opted for a poured-in-place concrete island. "We didn’t know if we could afford to do that, but we found a great subcontractor [Nate Francis of Countertop Creations] here who had never really built anything like that," Guess says. "Because he was interested in giving it a shot and adding it to his portfolio, he didn’t charge an exorbitant amount of money because it was sort of an experiment for him as well." The kitchen features a GE Profile refrigerator and KitchenAid range, microwave, and dishwasher. The sink and faucet are from Kohler. The project's builder was Joe Doherty with Custom Homecrafters of Austin.

At a seaside New Zealand house, the simple kitchen has strandboard cabinetry and an MDF island that conceals a fireplace at one end. The bright green cabinetry of the island are a happy pop of color that references the native greenery outside.

The kitchen features a concrete island topped with marble. Deja-Vu stools by Naoto Fukasawa surround the island. A print by Guy Gormley, as well as a painting bought during holiday in St. Tropez, hang on the walls.

Island Life The appealing, handcrafted appearance of the concrete kitchen island is a happy accident, the result of the concrete not settling fully in its timber framing. When the framing was removed, the builder, Peter Davidson, was worried that Davor and Abbe would be disappointed with the bubbled result and offered to start the process again, but they loved its one-off feeling and persuaded him to keep it that way.

Lambert pours wine in the kitchen, which is defined by a low concrete-block wall and serves as the home’s central core. The seating-area chairs are from Herman Miller.

The large, naturally lit kitchen is the heart of the house. Messmate-clad cupboards and huge expanses of glass dominate the space where Angelucci uses the sink, Gorman works at the kitchen island, and Pepa and Hazel look on. Play in the courtyard between the kitchen and garage is easily supervised and enclosed from the alley behind the house.

Concrete floors and an Ikea kitchen and spice rack make for an affordable, cleanly geometric aesthetic at the back of the bottom floor. The appliances are by Frigidaire, and the black countertops are sealed with Eco Tuff by Eco Procote.

"We really love to cook and much of our home life revolves around our kitchen. When we have friends over it’s great to buzz around here; it’s almost like a cooking show. We’re a very equal couple. We wanted the kitchen island to be a single form that we could both use. We can both cook and we can both wash the dishes. The whole thing is really easy to clean as it’s just one main surface that you can wipe down. So the preparation surfaces, the hob [cooktop], and the sink are accessible from both sides. It’s a simple, fun, form-follows-function principle: Store, wash, prepare, cook, eat."

Impromptu reading time in the open-plan kitchen is encouraged.

The kitchen worktop is framed in iron, and functional wheeled storage fits perfectly underneath. The full-wall shelving system offers ample storage for dishware and cooking accessories.

A nine-foot-tall door covered with quarter-inch white oak slides along a ceiling rail and can be moved with just a finger to close off Don and Lisa’s kitchen or bedroom. Made of wood and metal, and welded onsite, the door moves along 400-pound-capacity rollers by McMaster-Carr. A matching sliding door opposite hides a storage area. “Because of their size, the doors had to be made inside,” says Don, who did the job himself. mcmaster.com

Get the whole family involved in the kitchen, whether it be teaching young ones a tried-and-true recipe or exploring a new dish together.

At a home about half an hour from Lake Tahoe, architect Jack Hawkins and interior designer Cheryl Chenault built a house that would support their clients’ unique requirements in a home that would be 8,000 to 10,000 square feet. In the kitchen, two islands, one in the shape of an L and the other a smaller rectangular island, are layered table over one portion create generous space to spread out. Norman Cherner barstools from Design Within Reach line the island in the kitchen, which is crowned by an open loft office. The faucets are from Dornbracht; the countertops are Caesarstone. Hawkins integrated a steel-clad casual eating nook, at left.

In this kitchen, an exposed brick wall stands out against the milky smoothness of the marble tile floors.

The clients and design team chose to forego an open floor plan in favor of defined, separated spaces. In this scheme, the vertically oriented spaces act as a cinematic "hard-cut" to their horizontal counterparts. The custom hot rolled steel kitchen, one of these vertical transition spaces, receives light from above through a Velux skylight. A GE Profile Induction cooktop and oven and Miele refrigerator complete the space.

Jean-Christophe Aumas’ multihued Paris apartment houses both the highly sought artistic director and the stunning assemblage of furniture he’s brought back from his travels. Aumas designed the kitchen island, which is covered in marble tiles from Carrelages du Marais—the geometric floor tiles are from the same place—and strung the matrix of lights up above it. The barstools by Charlotte Perriand were discovered in a vintage store in Antwerp, Belgium. The green wall is covered in paint from Emery & Cie.

At breakfast, Arthur multitasks while seated at the dining table. He hand-stenciled the pattern on the wall in the background.

Stepstone's narrow concrete pavers add a graphic touch to the garden.

Don designed and built the white-oak kitchen table, which is cantilevered so knees don’t bump the underpinnings.

The cabinets are from Ikea, the range is by GE, and the Jenn-Air refrigerator is tucked unobtrusively into the pantry wall. The troweled concrete floor was poured in place by the builder, Peter Knudsen.

Six-year-old twins Nicolas and Constanza use Pentimento as their “little battleground,” says Pasternak. “They have some options here that they will not find anywhere else.” Among those options are a climbing wall offering easy access to the roof.

A spacious deck was created as part of the addition. A cantilevered concrete bench stretches out to the rear garden and complements the adjacent concrete wall.

When Belgian fashion retailer Nathalie Vandemoortele was seeking a new nest for her brood, she stumbled upon a fortresslike house in the countryside designed in 1972 by a pair of Ghent architects, Johan Raman and Fritz Schaffrath. While the Brutalist concrete architecture and petite but lush gardens suited her tastes to a tee, the interiors needed a few updates.

O’Sullivan designed the ceiling “to have a knitted or woven quality like that of wool or silk.” It dives down over the kitchen and dining area, eventually reaching a point at the entry that is low enough to touch. Here, resident Jes Wood leans against the onyx kitchen island while her daughter Ruby hangs out. Replica Jean Prouvé chairs surround the dining table; a vase by Bruce and Estelle Martin for Kamaka Pottery sits on top. The Reel table under the television is by Atelier Oï for B&B Italia.

In a couple’s Mexico City apartment designed by David Levy of Flexform, a Murano chandelier hangs above a marble-topped dining table from the showroom.

The Antonio Citterio walnut-back Morgan chairs are also from Flexform.

Just because your kitchen is on the smaller side doesn’t mean you can’t make it as efficient and effective as possible.

No whiteware here. In this moody apartment in Berlin, multi-toned charcoal gray subway tiles make up the backsplash, which contrasts with the pop of rosy color on the kitchen cabinets.

A new kitchen at the front of the house completes the trifecta of reworked rooms on the main level. It fits nicely into the notion of balancing new and old elements throughout the house, with oak detailing married to exposed brick, offset by strip lamps. The Hee bar stools are by HAY, the Caravaggio P3 pendants are by Light Years, and the range oven is from Britannia.

Make sure your kitchen fits seamlessly with the rest of your home. A good entertaining space should have a look that's consistent with the overall design, so use finishings, colors, and other elements that compliment the rest of the space.
