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 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.

The view!

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 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.

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.

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.

Light Box Peter created a simple uplight at the top of the wood box by wiring together energy-efficient fluorescent fixtures typically used under cabinets and countertops. “The cheaper magnetic models hum unacceptably loudly, so make sure you get the electronic ballast types,” he warns. He then painted the cavity white to reflect light and covered them with quarter-inch-thick acrylic from TAP Plastics. homedepot.com tapplastics.com

Natural wood trim—as opposed to laminate—is gaining steam in luxury car interiors. Various veneers are stores in a carefully monitored humidor before they're applied to models for armrests or dashboard and door details.

Here are some of the seat patterns for the various parts. Unlike a lounge chair or sofa found in your living room, this chair is made from many separate components, each positioned to optimize the piece.

The seatmaker sculpts a form out out of the foam. The more dense foam offers rigid support while the less dense sections conform more to a driver's body.

Seating is a large component of car interiors and evaluated on comfort, looks, and functionality. Very specific compositions of foam exist underneath the surface. The different densities create the support and comfort that's needed to make quick trips around town and long road trips equally enjoyable. Here's an example of the different foams in a seat.

Here's an example of all various wood accents one might see within a car. After the shape is contoured and refined by the designers and woodworkers—the same way as the steering wheel stitch is—it's then ok'd for production. This is just a glimpse of what goes into three components and similar processes occur for other parts.

The view of Kapiti Island is fully revealed from the tower.

For PS 234 in Manhattan's Tribeca neighborhood, Macrae-Gibson designed a colorful walkway to connect the main school building to a modern addition designed by the firm in 2008. The walkway, adjacent to a play yard, protects students and teachers from the elements as they move from one area to another.

The red steel-framed structure is lined with perforated metal panels in a variety of colors.

The Kelleys furnished the cottage with help from Suzanne’s daughter Betsy Burbank of Betsy Burbank Interiors. Classic modernist icons, such as a Saarinen Womb chair for Knoll, a Herman Miller Eames lounge chair, and an Eileen Grey E1027 side table look at home alongside present-day pieces such as an Encore sofa (which handily folds down into a sleeping surface) from Room & Board and a Doka rug designed and produced by Stephanie Odegard. The Wohlert pendant lights from Louis Poulsen were designed by Vilhelm Wohlert in 1959, but grouped as such, they appear distinctly contemporary.

The top container contains Wardell's office—and a "napping nook" above that.

In the dining area, a one-of-a-kind table with a reclaimed Carrara marble top by NET—themultidisciplinary design firm of architect Alejandro Sticotti, with whom Nicolas works—is surrounded by prototypes of the company’s Board chair. The family dog, China, sits on a floor made of travertine tiles.

The architects added a small circular skylight to serve as a vertical focal point in the center of the fifth floor. The quarter-sawn white oak risers produce a beautiful rippled grain highlighted by the abundant natural light.

After the foam configutation is set, the seat is upholstered and assembled.

The color, texture, and grain of a piece of leather is taken into account for upholstering an interior. Each car GM produces needs to be consistent and uniform in look and customization options. For example, if a buyer sees a caramel leather in a showroom car and wants it in their own, it needs to look the same. The studio makes sure that tanneries will be able to provide the right shade for a piece of leather and will be able to reproduce that on a large scale.

The yellow North Face tent looms over the top of the main building.

Yvette, Adrian, and their son Julian survey the view from the top-floor terrace. “I’ve never been fond of modernism—I find it cold,” Adrian admits. “But having this house, I have to say, it’s growing on me.”

Still, it’s possible to remove or relocate non-structural walls in a home with good bones.

Like the built-in bed, nightstands, headboard, and other custom furniture, the staircase leading to the open-air viewing platform was made by Versfeld. The Lektor desk lamps are by Rubn.

The master bedroom occupies a private space on the top floor.

Bold, red-colored shipping containers were used to create a (12 meter long) visitor area extension for the National Theatres Company of Korea. Designed as a social zone for theatregoers, the space was equipped with internal sliding partition walls that can be opened or closed to allow for flexible use of the interior spaces.
