Shipping containers: They're strong, durable and portable, stack easily and link together like Legos. About 25 million of these 20-by-40 feet multicolored boxes move through U.S. container ports a year, hauling children's toys, flat-screen TVs, computers, car parts, sneakers and sweaters.
But so much travel takes its toll, and after about eight years, the containers wear out and are retired. That's when architects and designers, especially those with a "green" bent, step in to turn these cast-off boxes into student housing in Amsterdam, artists' studios, emergency shelters, health clinics.
Despite an oft-reported glut of unused cargo containers lying idle around ports and ship yards - estimates have ranged from 700,000 to 2 million- the Intermodal Steel Building Units and Container Homes Association puts the number closer to 12,000, and that includes what's sold on Craigslist and eBay.
Hybrid Architecture in Seattle, which has built small cottages and office buildings from containers, coined the term "cargotecture" almost 10 years ago to describe this method of building. Co-founder Joel Egan cautions that although containers can sell for aound $2,500, they shouldn't be seen as a low-cost housing solution. "Ninety-five percent of the cost still remains," he says.
Here's a few recent North American projects where the shipping container takes center stage:
The Sunset Cargotecture House, Seattle: Home Sweet ContainerBuilt and designed by HyBrid Architecture as the Sunset magazine Idea House 2011, this 192-square-foot solar-powered backyard container cottage is not even half the size of a New York City studio apartment.
Still, it manages to pack in a galley kitchen and micro bathroom with a ceiling-mounted shower head - the floor's redwood slats hide a drain - and can sleep up to four (a bed unfolds from the wall, a couch converts, another bed can be added). But given the close quarters, it's probably best if everyone's related.

Five freestanding cargo containers lined up and cinched together on a 3,000-acre ranch in the rugged, rocky high desert mountains of West Texas reduces life to its basics: One container holds a living room; two house bedrooms and bathrooms; another a kitchen and eating area, while the last one is for storage.
Minimal modification was the goal here. "It was more about the arrangement of the boxes. Most architects see those containers, and they want to manipulate them too much and cut them all up," says Mark Wellen, who designed Cinco Camp for Roger Black, a former Rolling Stone and New York Times art director who'd grown sick of the Hamptons.
Stripped of their paint and topped with large roof canopies for shade, each box sits off the ground on short stilts. "There's rattlesnakes, scorpions, spiders, all kinds of bugs," says Wellen. "We made a conscious effort to get it off the ground."
Weirdly enough, a major east-west railroad runs through this middle-of-nowhere terrain three to five times a day, its long, distant cars loaded with shipping containers, a reminder from where this home came.

Rust-tinted brown wasn't the look the Box Office designers were going for. This three-story, 12,000-square-foot complex, which sits like a child's Lego dome in a post-industrial section of Providence is the largest office building in the United States made exclusively of cargo containers.
"The building is made of 140 tons of recycled steel, but it's very difficult for a green building to have an identity," says Peter Case, who developed and helped design the Box Office. "The bright paint, the solar panels on top get the message across that this is a green building."
Case abandoned plans for a conventional office complex when the economy faltered and instead bought 35 shipping containers. But, he says, with construction costs at $1.6 million, the containers didn't really save him money.
"A shipping container doesn't want to be a building," Case explains. "So you have to do quite a bit of gymnastics that cost money." But the building is four times more energy efficient than a typical office building, and that's where Case says he'll see savings. "There's no way for air to come in or out of a shipping container," he says, "unless you want it to."
Muvbox, Montreal: Take a Break in a CrateImage Credit: Courtest of Muvbox
An art object by night and a snack cart by day, this pop-up lobster shack opened in the Old Port of Montreal two years ago. Motorized and illuminated by solar-powered batteries, Muvbox opens and closes in about 90 seconds - the side panels unfold to become terraces with table-seating.
The brainchild of Daniel Noiseaux, the design-obsessed restaurateur who brought wood-oven pizza to Montreal 31 years ago, Muvbox was inspired by the horse-drawn snack carts and old-style canteens of centuries past, and Adam Kalkin's Push Button House installation.
While Montreal was first, Muvboxes have since surfaced in Paris, Toronto and New York's Times Square, where the lobster frescoes yield to black-and-white stripes, and the menu changes from lobster to hot dogs and bagels. A movable feast indeed.
DeKalb Market, Brooklyn, N.Y.: A Portable SoukImage Credit: Eddy Valante
A cluster of about 60 food and Etsy-style arts and clothing vendors operating out of shipping containers on a vacant Brooklyn lot, the DeKalb Market is no Dordoy Bazaar in Kyrgyzstan or Seven-Kilometer Market in Ukraine. The first U.S. container project of U.K.-based developer Urban Space - most famous for its Container City complexes in London - DeKalb dismantles in October to make way for a long-stalled housing-retail development as its planners scurry to find a new location. Good thing those containers are so portable.

Having had two restaurants fail on him, Kirk Lance vowed if he ever opened another he'd have to be able to pick it up and move it if it started to backslide.
Driving down the interstate in Oregon, where Lance had moved and had his eco-conscience raised, he noticed "giant yards … with hundreds, possibly thousands" of shipping containers stacked up and suddenly saw his next restaurant. He bought one, for about $3,000.
"It was the culmination of sustainability and recycling and portability all coming together," Lance says.
Turning the retired cargo vessel into a taqueria wasn't that hard, says Lance. Cutting out windows, spraying in the foam insulation, "anybody with a little construction background can probably figure those things out," he says.
But getting the permits, the blueprints, the structural engineering reports through the state of Oregon took four years, and added "a ton" to the cost, Lance says. "What kept me going was if I could build one of these things and it works well, I could just copy the blueprints and build 100 of them," or pick up and move.
The Shipping Container House, Nederland, Colo.: Still 'Cargotecture'Image Credit: Braden Gunem
True, the Shipping Container House is not all shipping containers, but by definition it's still cargotecture. The two containers that sandwich the main living area house an office and a bedroom in this 1,500-square-foot mountain home. Designed by Studio H:T in Boulder, Colo., for "a conscientious client who believes in living small and recycling," the solar-powered house can operate entirely off-grid.
