A small, single-story addition to the row house adds a playroom without eating up too much outdoor space. A green roof also helps makes up for lost garden beds, while creating attractive, leafy views from the second and third floors. In summer, when the sliding doors are left wide open, indoor and outdoor spaces blend together.

The master bathroom’s countertops are detailed with the same Carrara marble seen in the kitchen. The faucet and shower trims are by Kallista.

Purple thistles, California poppies, clover, and dandelions have all taken root in the roughly 10-inch-deep, lightweight humus and grape-husk soil in this 580-square-foot green roof. Designer Peter Liang says that he "wanted to plant a green roof for its thermal mass, but I wanted it to be as natural as possible."

The long rectangular Field House abuts what Burnette describes as a “memory orchard,” a grove of fruit trees just beyond the deck that was planted in honor of Geller’s late father.

Tina and Matthew Ford, here with daughter Daisy, are the owners of Shade House Development, the company that designed and is building the suite of houses that comprise Row on 25th in Houston, Texas.

The series of pitched white buildings was inspired by the work of architect Hugh Newell Jacobsen. “The shell of the house is a very simple form,” says Matthew Ford, “no turns or intersecting roof sections. This allowed me to use solid but inexpensive framing and roofing crews. We are always looking for the point where simplicity and luxury meet.”

Author and French designer Daniel Rozensztroch's industrial loft was a 17th-century manufacturing plant in the Marais, a historic district that abuts the Bastille. A row of vintage iron cabinets, mostly recovered from doctors’ and dentists’ offices, separate the kitchen from the dining area. The Gervasoni table was designed by close friend Paola Navone. Architect Dominique Perrault and designer Gaëlle Lauriot-Prévost are responsible for the the tubular pendants over the dining table, which resemble old subway lamps.

Stainless steel was selected for the kitchen countertops, and the pair relied on a local industrial sheet metal fabricator to help them prepare the material for residential application. The mix of warm and cool adds depth and dimension to the space.

Heywood lives in Oakland with his wife, two small children, and lots of books. The young boys provide the abstract paintings that grace the walls.

Childrens’ bedrooms are reimagined as cozy private cubbies, much like sleeper cars on a train. These compact rooms were designed to encourage outside interaction with the rest of the household during the non-sleeping hours of the day. Sliding doors and baltic birch built-ins complete the rooms.

The owners toured this home, which surrounds a mature tipu tipu tree, while visiting relatives for the day. The brick is original to the 1947 construction.

Sliding doors by Quantum were made to look like the original panes that couldn't be saved, and they lead to a fire pit outside.

At the top of the stairwell, a sitting area is outfitted with a vintage Eames lounge, a large Jack Goldstein painting, and a 1970s light fixture found by Marcovitz in Paris.

The view!

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.

Light from a new skylight pours into the home's entryway and living room. Steel columns and beams were added for structural reinforcement, and the couple left all beams, old and new, exposed.

"I always wanted to have my very own yellow brick road," says Viviana de Loera, whose favorite part of the home is the playful staircase. The original stairs and handrail were preserved in the renovation.

In the living room, and throughout the home, recessed "book nooks" are used to provide space-saving storage. The only seating in the room is a sleek black faux leather and steel daybed, fabricated by Montreal-based Surface Jalouse. Walls were removed to cohesively unite the living space and kitchen.

Rustic meets modern in this bedroom, where white track lighting beautifully illuminates a black wall and serves as accent lighting for vintage wall art.

Take a look at some of the most exciting, sustainable buildings around the world, and you may notice something they have in common: green roofs, or rooftops covered with a thin layer of soil to allow for grasses and other low-lying plants to grow.

“We brought the cedar siding of the exterior inside strategically, both to blur inside and out and to give texture,” Young says. “Simple forms and clean lines, if done right, have a calming effect and nicely contrast the furnishings.” The master bedroom features the same western red cedar as the exterior, and lighting by David Weeks Studio.

Not everyone has a credibility bookcase. Your kids’ discarded toys and jackets may be strewn on the floor, or your roommate is in the throes of an online boxing class. Perhaps your cat is licking its unmentionables, and it’s not quite the scene you want to set for your one-on-one. Luckily, Zoom makes it easy to manifest the environment we want if the environment we have isn’t ideal. If you’ve ever wanted to dial in from a Dwell house, now’s your chance.

New Depths Inspired by a local winery, George Kyprianou wanted a glass top on his subterranean wine cellar. The interior is lit, casting soft light into the living space at night and revealing the 132-year-old stone foundation. The three-quarter-inch glass lid sits flush with the floorboards; it opens with an ingenious device that Kyprianou devised using a 12-volt air compressor and a remote-controlled switch. When you push the button, the glass lifts just enough to be removed by hand.

Fleetwood Windows & Doors gave the home ample access to sunlight. Matching CB2 lounge chairs face the pool.

For a concrete guesthouse in Stone Ridge, New York, LevenBetts designed an onsen-inspired bathroom with a steam room and a hinoki tub.

Antarctica - Setting foot on the 7th continent Private tour groups have been visiting Antarctica since 1969. Today there are lots of choices among operators sending ships, planes, and helicopters to Antarctica between November and March (the summer season). Many trips start in Southern Argentina, and ship-bound journeys include on-board lectures and access to experts on the ecology of the Antarctic during the cruise. Passengers can kayak around icebergs, or spend a day watching penguins, seals, and whales off the coast. Photo by: Christopher.Michel

North America - Biking the wine valleys of Northern California Almost half of the wineries in the United States are located in California, and many of those are in the valleys north of San Francisco. Wine tasting and winery tours are a drunkenly entertaining way to learn how grapes become wine, but the process involves more than crushing and fermenting grapes. One needs to see the agriculture that goes into America’s wine making, and touch the grapes on the vine, to really appreciate the drink. Work off that hangover by cycling along the winding roads of Napa and Sonoma. Photo by: needoptic

South America - Volunteering in the Peruvian Amazon The Peruvian Amazon is only home to 5% of Peru’s human population, but about 5,500 plant species and 760 animal species unique to Peru live here. Animal rehabilitation centers protect sections of this diverse ecosystem, and trained conservationists help create a safe place for wounded and sick animals. The goal of these reserves is to release healthy animals back into the jungle and teach visitors about the importance of the Amazon. Many encourage volunteers to become involved in the care and preservation of the Peruvian Amazon, giving them a firsthand understanding of the region's ecological diversity. Photo by: cavallotkd

Europe - Touring the cultural centers of Central and Eastern Europe Paris and Rome are beautiful, but there's more to Europe than taking the elevator to the top of the Eiffel Tower and eating gelato at the Colosseum. Eastern Europe is home to castles, cathedrals, world-famous symphonies, modern art museums, and great beer, wine, and pastries. The cities of Berlin, Warsaw, Krakow, Prague, and Budapest are important cultural centers with citywide art and architecture dating back to the Renaissance. Charles Bridge in Prague has been standing since the 12th century, and Vienna’s city center is home to both Habsburg architecture and modern design. Photo by: Dimitry B

Africa - Summitting and safariing in Tanzania At 19,341 feet, Kilimanjaro is the tallest mountain in Africa. It takes a minimum of six to eight days to reach the summit, during which climbers contend with not only changes in altitude, but changes in climate as well (snowstorms occur close to Kilimanjaro's peak). But reaching the top via one of six routes is a serious achievement, and offers the chance to see both Tanzania and Kenya from above. Serengeti National Park is a five-hour drive, or short flight, from Kilimanjaro airport and is home to some of Tanzania’s biggest animals, including lions, cheetahs, leopards, elephants, and rhinos. The park has safari lodges and campsites, and tour operators organize excursions throughout the park. Photo by: Tambako the Jaguar

Asia - Exploring nature and culture in China The Chengdu region of China is home to the world's largest population of Giant Pandas. Panda reserves in and around Chengdu focus on protecting the bear’s natural habitat and researching their behavior (best job ever?). Certain reserves allow volunteers to interact with and care for these endangered species. Elsewhere in China, Beijing has some of the country's most important cultural landmarks. Principal among them is the Forbidden City, built during the Ming Dynasty and now home to the Palace Museum. Xi’an, located between Beijing and Chengdu, has the Terra Cotta Warriors archaeological site. This necropolis was originally built for Qin Shi Huang, the first emperor of China, and is thought to have contained over 4,000 life-size soldiers and other figures sculpted out of terracotta.

Australia - Transitioning from Outback to tropics by train Riding the Ghan makes for a three-day transcontinental train journey over the plains, deserts, and mountains of central Australia. The route starts either near the beaches of Adelaide, the capital of South Australia, or north in Darwin. In between, travelers get a sense of the continent's changing environment as they trundle to Alice Springs, from which a six-hour drive will bring them to Uluru (Ayers Rock). Near the top of the Northern Territory, travelers can stop at Katherine and spend a day at nearby Nitmiluk National Park, a tropical counterpoint to the arid Outback. Photo by: huskyte77

A primary suite was created on the new second level, complete with a freestanding tub.

Mark Fekete and Viviana de Loera, co-founders of interdisciplinary design firm MARK + VIVI, happily took on the challenge of building their dream home in a transitioning Montreal neighborhood. The couple's kitchen is an exercise in both sustainability and creativity. The island is wrapped with reclaimed scrap wood uncovered from the house during demolition. Chalkboard walls provide a whimsical canvas for graphic images and notes. Stainless steel was selected for the kitchen countertops, and the pair relied on a local industrial sheet metal fabricator to help them prepare the material for residential application. The mix of warm and cool adds depth and dimension to the space.
