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 master bathroom is a calming oasis of marble. The couple often relax here for a moment of tranquility.

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.

Lightroom 1.0, a photography studio, is a freestanding structure on the property. “Together, they represent an autobiography of my career,” Carpenter says.

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 packaging can be seen as a vehicle of our values: functionality, sustainability, natural materials, aesthetics, ethics, and ecology.”—Marianne Goebl, global director of Artek

Fashion designer Josie and her husband Ken Natori are big fans of traditional Japanese architecture, so when Brooklyn-based practice Tsao & McKown Architects designed their home in Pound Ridge, New York, they used a heavy, exposed-timber structure, and included Japanese-style gardens and landscaping.

The owners of this 2,300-square-foot converted loft in SoHo have a penchant for color and collections. To make way for these elements, BC-OA kept new materials simple and desaturated with super white walls; oil-finished, white oak flooring; and white lacquered cabinetry. In the dining area, a custom designed, built-in, tufted banquette adds soft juxtaposition against the live edge dining table. The velvet upholstery is meant to provide contrast against the exposed, white-washed original brick in both texture and era. Overhead a brass chandelier with exposed Edison bulbs references the former Swan Incandescent Electric Light Co. which occupied the loft after construction was completed in 1897.

A look at the home's front facade. In a Melbourne suburb, Splinter Society Architecture designed the versatile home for Mark and Cara Harbottle and their three young children.

Inspired by modern Japanese minimalism, Hong Kong practice JAAK demolished the walls of this two-bedroom apartment and remodelled it into a studio with an

The living area boasts nearly 10-foot-high ceilings that impart a feeling of airiness and spaciousness. Discreet, built-in storage in the floor at the top of the steps prevents clutter from accumulating.

"In this project, we got so much benefit out of this 'secret garden' for the master suite along with all of these environmental benefits that the residents were excited to embrace. It's one of the pieces we are happiest about," says architect Jonathan Feldman.

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

Moonshine is beautifully set in an isolated spot in the English countryside outside of Bath. The dramatic juxtaposition of a stone gamekeeper's cottage and a modern timber framed addition gives the home a quaint, pastoral feel while capitalizing on the dramatic view of St. Catherine's Valley.

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.

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 Mohican tiny home has a starting price of $62,000, and it’s made by Amish craftsmen in Ohio. The 20' tiny home, which can be built in as little as eight weeks, has an unfinished exterior and a light and bright, minimalist interior that packs all the essentials into a compact footprint.

At 220 square feet, The Wheel Pad's mission is to build socially-conscious, environmentally-friendly transitional housing for people newly using wheelchairs. Their universally accessible design can connect to an existing house or be accessed via an independent ramp and they offer customization options such as a composting toilet, and solar panels. Pricing starts at $60,000 with leasing available at $3,000 a month.

Hangar Meeting Table for MG LAB – This table premiered in 2012. It was designed with a space underneath the tabletop to stow away electronic devices that need to be close at hand without contributing to tabletop clutter.

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.
