Architect Gregory Phillips connected the original house to a new modern extension that doesn’t interfere with the surrounding houses. “I try to be true to the location,”he explains, “so it doesn’t seem like some spaceship has landed.”

This 3,200-square-foot structure was assembled with a prefabricated foundation, concrete panel siding, and efficient built-ins, minimizing construction debris and toxins—such as concrete foundation tar—on the site.

Yang Yeo and his girlfriend Ching Ian relax on the back stoop of their renovated and radically updated Singapore shophouse—an archetypal building type in this busy port city. “Shophouses brought back memories of our childhood,” says Yeo.

The beanbag chairs and outdoor sofa and chairs are from West Elm and the Case Study Museum Bench is from Modernica.

The hardscaping helps keep water use to a minimum. The Lais used gravel—accented by drought-tolerant bamboo—to create their side yard.

This dwelling joins a number of structures—such as a boathouse and guesthouse—owned by one family and used for vacations. They needed a new house to accommodate new generations at the reatreat.

Masahiro and Mao Harada of Mount Fuji Architects Studio wanted to break with the traditional definition of a house when they designed this small Tokyo home. They achieved their goal by using the same material for the ceiling, the walls, and the floor, creating a space that flows beautifully. Photo by Ryota Atarashi.

Though the front of this 1880s home in Adelaide, Australia, maintains a traditional facade due to strict heritage laws, the rear is modern eye candy at its best. See more of the home.

In fall, the color of this backyard in Charlottesville, Virginia, changes daily with the foliage. Elizabeth Birdsall marvels how new outdoor spaces on her property, like a patio furnished with upholstered seating from Gloster, make enjoying the woods an easy experience: “It’s like comfortable camping, all the time.”

When the Ferguson Sauder family—parents Meg, a school counselor, and Tim, a design instructor, plus kids Cole, Olive, and Asher—wanted a multifunctional backyard addition, they decided to build it themselves. Two Liftoff chairs by Tim Miller, one of Tim’s former students, surround an oil-drum fire pit set in granite dug up on the property. On the deck, the Panamericana chair is by Industry of All Nations.

Escape made a splash by launching a property in Tampa Bay filled with its trailers. But you don’t have to live there to own one.

The first thing landscape designer Laura Cooper asked Devis and Purdy was to recall childhood gardens and outdoor play. In that spirit, she designed their backyard, integrating the high ground with the low just outside the “kids’ wing.” The resulting series of outdoor rooms on this quarter-acre is full of memory and play.

Working with a limited budget, First Lamp designed and built one principle architectural flourish: exposed Douglas fir rafters that would weather to a brighter red over the years and accent the white siding.

The modern addition sits on a concrete platform that extends past the house’s envelope, creating welcoming patios on each side. “From any space within the home you are no more than a few steps from one of the outdoor spaces,” Busick says. On the west-facing back porch, Green Kite Chairs by Karim Rashid and a poppy-red hammock offer ideal spots from which to take in the sunset.

Lisette requested the central work island, which cantilevers over the pool.

“I love the look of mass plantings,” notes Neely, near Mexican feather grasses--which thrive on the sunny lot.

One of the main goals of the construction was to do as little harm as possible to the existing environment, which includes waterways that salmon depend upon. Herrin and his team created a garden roof that covers the full extent of the home to meet this objective. “This helps control storm water runoff and also replaces lost insect habitat—insects being a critical food source for juvenile salmon,” he says.

The architects worked closely with the clients to match the aesthetic of the vintage furniture they collect. The midcentury modern Danish chair, seen right, has been refurbished and reupholstered.

Wood from the property’s felled trees was incorporated into every room in the 3,000-square-foot house.

Located in California’s Sugar Bowl neighborhood, this shadowy lair by Mork-Ulnes Architects looks like something out of fairy tale. "We call the house Troll Hus, with a reference to the otherworldly beings in Norse mythology and Scandinavian folklore that are said to dwell in remote mountains," architect Casper Mork-Ulnes says.

Unable to alter the footprint of the building, the Deams created a backyard living area that nearly doubled the home's living space.

Erin Moore of FLOAT Architectural Research and Design, based in Tucson, Arizona, designed a 70-square-foot writer’s retreat in Wren, Oregon, for her mother, Kathleen Dean Moore, a nature writer and professor of philosophy at nearby Oregon State University. The elder Moore wanted a small studio in which to work and observe the delicate wetland ecosystem on the banks of the Marys River. Enlisting her daughter’s design expertise, her professor husband’s carpentry savoir faire, the aid of friends, and a front loader, Kathleen and her crew erected the structure in September 2007.

Totally off the grid—–Kathleen forgoes the computer and writes by hand when there—–the Watershed was designed to tread as lightly on the fragile ecosystem as the wild turkeys and Western pond turtles that live nearby. “

The roughly 160-square-foot modules, dubbed Mini House 2.0, were built in collaboration with Swedish manufacturer Sommarnöjen, and are delivered flat-packed. The homes are painted wood, and include a shaded deck space, plus full insulation and electricity, for a price of about $29,000. The modules come in various layouts, and can be configured and combined to include a kitchen, bedroom, bathroom, and living space.

A polychrome facade made of salvaged, 100-year-old barnwood gives this small, lofted cottage space its unique character. Its copper roof is also reclaimed, a lucky Craigslist find from a local remodel. Though the structure has a footprint of just 11' x 14', it provides a useful space to entertain, catch up on work, or relax.

The material was gathered from soil with high sand content on the property as well as a second site in the vicinity. Certain volumes of the home consist of a concrete structure and brick masonry.

Anka Lamprecht and Lukas Wezel shared their rustic domicile in a valley in Grotli, Norway. Boasting an enviable view, it’s the first cabin archived in the book’s “Backcountry” category that features homesteads in the wilderness.

The steel structure is suspended two feet above the roof of the existing bungalow, supported by four steel columns, one of which screens utility lines running from the Perch to the house below.

The wood-wrapped tiny home features a deck pierced by a tree trunk.

A gravel path leads to a guesthouse, where Trainor supplemented an existing garden of yuccas and palm trees with succulent aeoniums and flowering euphorbias.

Utility equipment and storage is hidden in the hexagonal "systems ring" below the living space modules.

On an idyllic afternoon, members of the Oropeza and Castillo clans splash in the backyard pool framed by Trex decking and outfitted with furniture by Móbica.

The house is oriented toward the expansive backyard, where the family spends 80 percent of its time. Alfredo’s wife Lorena, son Lorenzo, nieces Camila and Valentina, and Castillo’s daughter, Regina, hang out by the pool—the focal point of Transepto’s restrained landscape design.
