Howard and Shumate in the living room, where Commune designer Steven Johanknecht introduced custom built-in daybeds with storage beneath. The carpet-fragment pillows are from Commune, as is the table, designed by Joshua Tree–based sculptor Alma Allen. The poster is by Mike Mills.

The kitchen cabinetry echoes the new blue ceiling. The brick tile is from Heath Ceramics, as is the dinnerware. Behind the Viking stove is powder-coated corrugated metal (“Very trailer,” says the designer). The refrigerator is from Big Chill. On the table is a bowl by Victoria Morris.

More fragment pillows adorn the bed, which is covered in a reversible bedspread by artist Jane Kifer. To the left of the window is a painting by Shumate.

Architect Christopher C. Deam, Dwell founder Lara Deam's husband, designed Airstream's newest travel trailer, the International Sterling.

The courtyard is just one of many open spaces that will be highly utilized—in the non-winter months anyway. Concrete worked well with developing the language of FlatPak. The second level is a wood panel that can be clad in corrugated metal or cedar—different layers that can be plugged in like covers on your cellphone.

Once a classic trailer-park scheme of mint green and white, the exterior of Commune Images owner Sofie Howard’s 500-square-foot Malibu trailer was distinctively repainted. The gate is a patchwork of scrap wood pieces. Partly inspired by 1970s Vans slip-ons, Howard’s boyfriend, artist Grant Shumate, painted accent lines on the side of the trailer. The porch houses a seating area with handmade MORERA Boxes from Commune, and a new outdoor shower. The entrance is beneath the wood-framed canopy.

Gaffney's cousin lives in the house just in front. To give a bit of perspective, this photo was likely taken just feet in front of the waist-high wall that runs between the two houses's yards.

The main room serves as a living/dining/kitchen area, where there is just enough room for a Saarinen table surrounded by Nakashima chairs. Johanknecht added the cork floor, and the custom stained-glass design on the Dutch door is by artist Steve Halderman.

A familiar scene in the Benoit home: Peter paints at the Steelcase desk—"I do all my work here," he says—while Ando sits nearby, waiting for attention.

Texas. The Cricket Trailer, made in Houston, can sleep up to two adults and two children. With integrated fresh water and greywater tanks along with a water heater, campers can live off-the-grid in the easily towable unit.

Inspired by the sea and sand, Richard and Jackie Willcocks chose blue and orange joinery colors for their 1,140-square-foot prefab. The modular home is by New South Wales company ArchiBlox.

Night settles in around the wanderers sheltered in El Cosmico's teepees and trailers. As El Cosmico shows, understanding a small space involves understanding the infinitude of the world beyond them.

With the residents awake inside, this trailer's burnished glow reflects the sunset.

A good dose of inspiration from Luis Barragán turned a dark and beleaguered midcentury house into a family home for the ages. The paint colors chosen by the residents and architect Linda Taalman are American Cheese and Blushing Bride, both by Benjamin Moore, creating a tapestry of color and texture.

For her family’s house near Melbourne, Anna Horne created a series of prefab wood modules using a design from the company Prebuilt. She found the old industrial letter at a factory; it stands for Somerset, the name of the house.

The blue ceiling continues into the bedroom, filled with art by Howard’s friends. The yellow-and-white poster is by Mike Mills, and the signed Rolling Stones drumhead was a gift. “It feels like a New York apartment at the beach,” says Shumate.

The back of the house has sliding doors that open far enough to expose the entire livingroom to the families' back yard.

A new addition to Sea Ranch’s enclave of utopian homes, this structure (and the separate guesthouse seen here) clad in rough concrete and Cor-ten steel seamlessly blends in with its half-a-century-old California neighbors. Designed by the dean of the Woodbury School of Architecture and the head of the University of Oregon’s architecture department, its spaces flow into one another underneath an angled plywood ceiling and illuminate built-in furniture crafted from vertical-grain Douglas fir.

The Leaf House is a lightweight, mobile trailer that was carefully engineered to weigh less than 5,000 pounds. The designer, Laird Herbert, used a metal-mesh, open-joint rainscreen as the cladding on the front end, and spruce pine at the back.

On one side of the house, a white central staircase leads to a split-level landing the Robertsons call "the reading room." "We needed a place to hang out and for the kids to read," explains owner Vivi Nguyen-Robertson. Awaiting the birth of the couple's son, she relaxes in a built-in reading nook in the library.

Roberto Burneo designed this home for his eldest niece, her husband, and their three young children in a suburb outside Quito, the capital of Ecuador. The house is set on a flat expanse of land with fruit trees, and Burneo's design "guides the social areas inward in order to link them to the gardens.”

A sky-blue vintage trailer blends in with the sky.

"I like the more boxy, modern look," Herbert says, "and I think it fits the small space better. You have more space in a box. As soon as you put a peak on a roof, you lose a lot of that usable space."

The ground-floor sauna, one of the home’s central gathering spots, is built from stained alder. The electric heater is from the Finnish company Iki.

Burneo took advantage of the perpendicular orientation of the volumes to create outdoor spaces that look out to the gardens.

Designed in 1960, the house was originally a lodge to accommodate horse trails. Throughout the years, the house has expanded with various additions and renovations.

Sawn wood planks add texture to the interior walls.

Burneo oriented the house in a pair of perpendicular volumes. The ground floor houses the public areas, including a study, while the top volume, housing the bedrooms and a family room, is oriented north-south, allowing for warm sunlight and a visual orientation toward the gardens.

By reducing the bedroom to its essentials and filling it with windows, the El Cosmico staff has made this small space as expansive as the desert beyond.

When the Casali family gave Michael Krus and Prishram Jain of TACT Architecture free rein to work with unconventional materials, the architects responded by creating a geometric 4,300-square-foot smart home encased in aluminum panels by Agway Metals. The front facade features Cor-Ten steel fabricated by Praxy Cladding.

The custom kitchen counters are concrete, and the yellow dining chairs add a welcome splash of color.

A super-insulated envelope and a heat-recovery ventilator help keep the Leaf House comfortably warm, even in the brutally cold Canadian winters.

“There’s a presence to that place—it’s vast, and constantly shifting,” Moffitt says. “It was clear that this house should be an observation shed for the changing landscape beyond.”

Burneo added exposed brick to his palette of interior materials.
