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

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.

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.

“I read a story about a student in a small one-bedroom apartment who because she could only fit her big bed and her desk in the apartment, was too ashamed to invite her friends or her parents over,” remembers Van Bo about his inspiration for this crafty ensemble of furniture. “There was nowhere to cook, nowhere to sit, not even space for standard chairs to fit. It made me think ‘Where do we find the instruction manual for how to use a small space?’ We buy a new computer or a new vacuum cleaner and we are given instructions. But nobody teaches us how to use space”. So he designed plans for a small one-bedroom apartment that included a room-dividing piece (the Siwo Couch) that functions as an all-in-one couch, pull-out king size bed and bench that seats six to nine people, a miraculously problem-solving invention, along with custom-sized smaller chairs that double as tables. “Design is a social issue,” says Van Bo, “it facilitates or negates social interaction depending on its cleverness, use and beauty. Wohnung makes socializing possible and enjoyable in a small space, on a small budget”.

Born in Rome in 1914, Lina Bo Bardi emigrated to Brazil in 1946.

Vriesendorp also crafted a series of paper hands, a reference to Bo Bardi's habit of drawing attention to important details in her notes.

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.

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

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.

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.

Contemporary materials like zinc and glass contrast with a cast iron facade and slate roofs.

Can't find the right table for your space? Another option is to have a custom top cut for a recycled base, which is what the Deams did for their outdoor dining area. They had an existing Scissor table base by Bay Area designer John Randolph sitting unused, so Chris had a piece of hardy soapstone (it stands up to high temperatures) cut to match by Fox Marble. A subtle facet at each corner plays off the base's design and lends a more intimate feel to the long table. For a fraction of the cost of a full piece, the bases of design classics are often available on Craigslist and eBay.

Architect Lina Bo Bardi embraced the vernacular design traditions while pushing new forms forward. Her use of not only wood but fabrics and leathers stand out in several of her designs. Her furniture was often designed only for her buildings. This group of chairs was created between the 1950s and the 1980s.

Included here are the Bola armchair designed by Lina Bo Bardi (1951), a pine chair designed by Lina Bo Bardi, Marcelo Ferraz and Marcelo Suzuki for the SESC-Pompéia Center (1980s), and a folding chair with a jacaranda frame designed by Lina Bo Bardi for Studio de Arte Palma (circa 1950).

In 1953, the American magazine Interiors praised Bo Bardi's Bowl chair by comparing it to the work of Eero Saarinen and Irene Schawinsky.
