In search of the perfect shape, Bogobrush began by finding used and abused toothrbushes from around the world. The brush's easy cylindrical form allows you to effortlessly brush using any hand and any part of your mouth.

The size of the house was determined by the radius of the crane needed to drill the foundations for the 11 piles that stabilize the building. From its position parked in a gracious neighbor's driveway, the crane could reach 70 feet into the property.

The working color palettes are hues of pinks but Campbell is musing about introducing blues and indigos.

Intelligent design: The future of the office is about providing a balanced response to the environment and the person in the office—at home, in the park, on a plane, or wherever the “office” happens to be.

How did the collaboration come about with Soma Water? After meeting with Mike we were immediately drawn to the idea of rethinking how we filter our water while also helping to solve the global water problem. There was great synergy and chemistry and we started to get to work. Tell us a little more about the design process. We set out to create the best water drinking experience and brainstormed different ideas and scenarios. We then created a few concepts and prototypes to validate our ideas. Soma went with the most iconic which happened to be one of the more challenging designs to make into a real product. We had to fail a lot along the way, chartering new territory, exploring what worked and what didn't, but we were also able to apply and further develop and apply our design process to facilitate creative decision-making and hone in on making the best idea a tangible reality. Looking back, this was an amazing process to see a big idea come to life.

MNML sought out to create an all-season ride that exemplified the idea of rugged refinement, as Watson put it, reflecting the studio’s usual philosophy of reduction and purity. The team tackled the problem by doing exhaustive field research and then building a story—a day in the life of a cyclist that would serve as the litmus test for whether the final design really works. Chicago shapes the narrative—dealing with inclement weather, hauling a ride up to a walkup apartment ,and navigating potholes. Photo courtesy of MNML.

A sketch done by Halprin references the "Sierra at 11,000 feet" and muses that the rock could inspire a possible "wall for Portland fountain."

This collection from Kingsnorth combines vintage chair frames with biomorphic fabric forms, making each chair a truly unique and one of a kind piece.

Sketch of Shanty Cabinet Design These cabinets elevate corrugated steel from mere industrial functionality. They also celebrate contemporary design that’s not coming from a strictly European approach, according to Doshi.

Illustrator and designer Mark McGinnis creates graphic prints that expertly blend line and color. His Menagerie Collection presents a series of prints that depict animals and flora in a range of soft, yet vibrant colors. Although compositionally simple, each print is comprised of several parts—the graphic is screen-printed on 140 lb. arches watercolor paper, after which McGinnis fills the colored print with a hand-drawn line sketch, ensuring that no two prints are exactly the same. From there, the 100 percent cotton paper is mounted and framed in an ash wood frame. Each print in the series, like this Red Bull, can be used on its own, or coordinated with other prints in the series to create a menagerie of wall art. Each limited edition print is exclusive to the Dwell Store and is signed on the left side of the print, and numbered on the right.

Jeff Kovel likes to integrate nature into his office interiors. The sketches for Skylab's North project outline a design similar to workspaces built for polar explorers.

"This was an experiment in getting away from having a conventional leg in each corner," Barber says. "We wanted to find a different way to put the sofa together." The cast metal foot joins the seat, back, and arm elements and solves challenges with moving sofas around. From a shipping standpoint, the sofa fits into smaller boxes since the individual pieces can be separated. From a user perspective, the smaller components make it easier to negotiate narrow doorways and winding stairwells. Instead of lugging an entire six-foot-long sofa up many flights of stairs, people can move smaller portions and reassemble them once the piece is in a room. "Getting big sofas in and out of houses is a massive problem," Barber says. "This breaks down into individual panels so you can just literally take panel after panel and get it into anywhere. There’s innovation in the way it’s put together, innovation in terms of its shipping, and innovation in its installation."

The Hollyhock House Was Supposed to Have a Small Schoolhouse Wright’s first L.A. project, the private home of Aline Barnsdall and her daughter, was meant to be part of a larger collection of buildings, including a theater and cinema all set on the 36-acre plot on Olive Hill. While many of the initial additions weren't finished because of budgetary reasons and aesthetic differences, a proposed schoolhouse was halted due to code issues. Named the Little Dipper, since the footprints of the foundation mimicked the constellation, the proposed one-room building was to be made of concrete blocks and contain a raised stage and fireplace. After construction was halted, it was turned into a garden.

Ground Zero Master Plan (New York City) Studio Daniel Libeskind designed the master plan for Ground Zero, a complete redevelopment that features three new towers, a transporation hub, and a museum. Libeskind has been working with firms including Snøhetta, Skidmore, Owings & Merrill, and Santiago Calatrava, to reimagine the Lower Manhattan site.

De Lucchi’s study of the human body accompanying his sketches for The Walk is modeled after himself—De Lucchi is known to be a peripatetic roamer, and the act of walking often appears in his creative projects. De Lucchi’s ideas are informed by long-held beliefs about the nature of creativity and memory. Case in point: his sprawling studio in Milan is spread over several floors separated by flights of stairs and divided into zones, ensuring that he and his design acolytes are in a constant state of motion, and creation.

An early sketch of the chair shows Opsvik’s concept of an ergonomic design for users of varying heights and sizes. Here, the sitter’s elbow is shown aligned at table height, regardless of body size.

He Conceived of a Gorgeous Headquarters for the Lenkurt Electric Company While Wright displayed a keen understanding of the roles cars played in modern America and incorporated them into his designs, for his proposed corporate headquarters for the Lenkurt Electric Company in San Carlos, California, he surreptitiously swept them under the rug. By placing the car park underneath the building, he gained the space to create a sprawling structure that built upon ideas developed for the famous Johnson Administration Building in Racine, Wisconsin. This exceptional sketch depicts the structure at night, when a proposed grid of pyramidal skylights made from copper and glass resemble a luminous tent city. It’s a glowing testament to modernity, fitting for a mid-century company that made microwaves and telephones. Photo courtesy Frank Lloyd Wright Foundation
