The glass-enclosed master bedroom floats above the corrugated, oxidized steel exterior.

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."

Suzanne and Brooks Kelley at the back of their 1,100-square-foot guest cottage.

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.

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 view!

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.

Architect Tamira Sawatzky and artist Elle Flanders get an awfully good view of their busy Toronto street from their office and dining room.

The table is by Made, the sneaker-inspired Shoe Toss pendants are by Jeremy Hatch of Ricochet Studio, and the laser-cut photo on the wall is by the couple’s collective art and design practice, Public Studio.

A NOR11 chair anchors a sunny corner.

The facade features a sunny yellow balcony—intended to spark a smile, but it’s also a statement by the architects against the “monotonous and dull color palette” of traditional Japanese neighborhoods.

The idea of balance is expressed in all facets of the project—from light to dark, indoor to outdoor.

In the living quarters of Lightroom 2.0, Carpenter’s daughter Esme chats with her boyfriend, who is seated on a Milo Baughman Case Sofa.

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.

Lightroom 2.0 was inspired by artists’ lofts and Decatur’s industrial past. The gallery floors are polished concrete and the exposed joists are Georgia-Pacific engineered lumber.

Located beneath a netting, Wolberg's multifunctional LIVE IN project packs a range of personal configurations into a 131-square-foot unit, including work, play, and sleep.

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.

The holistic LIVE IN also incorporates space for practical necessities, like sleep.

Intimate nooks, set amid curvaceous shapes, diffused lighting, and colorful accents, provide a place for rest and recreation. The various levels, including the netting above, playfully engage the space.

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 view of Kapiti Island is fully revealed from the tower.

Braun ET66 Calculator When it originally debuted in 1987, Braun’s iconic ET66 helped elevate the calculator to an everyday personal item. Its sleek styling, slim plastic casing and approachable interface were the masterstroke of influential German designer Dieter Rams and his partner at Braun, Dietrich Lubs. Here the ET66 eight-digit calculator is faithfully reproduced, down to the inviting round buttons and high-contrast palette of its number and function buttons.

After a 40-year-old pine tree fell over on a Brentwood estate in Los Angeles, the owner let it lie, and the continued to grow from its newfound horizontal position. He decided to incorporate it into a 172-square-foot office and guest house with the structure floating above the tree. Around the perimeter of the butterfly roof is a clerestory that gives the illusion that the roof is floating.

On the lower roof, cedar decking and flower beds define one of several outdoor gardening spaces. Part of her ongoing research into the livability of cities, Fitzgerald aimed to create landscaped areas that were “aesthetic, aromatic, educational, and productive.” The deck is bordered by an expanded aluminum mesh railing and black metal corrugated panels.

Challenged by the dimensions of the narrow lot, the team worked through significant programmatic and logistical constraints during the design and construction process. The final concept for the layout was a modern take on the side hall plan. The living spaces are stretched back deep into the lot, and strategically raised above grade to allow sunlight to penetrate into multiple living spaces. The multifunctional courtyard serves as outdoor workspace, gardening area, children's play area, and covered parking during winter months.

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

Carpenter kicks back on an IKEA outdoor sectional on the sealed-pine roof deck of Lightroom 2.0. A collection of vintage Tulip armchairs by Eero Saarinen surround a “Jetsons-inspired” fireplace from the 1970s found online.

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 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 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.
