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."

A PK 22 Easy Chair by Poul Kjaerholm for Fritz Hansen adds a dash of yellow to the breakfast room.

It might not make you popular with your contractor, but for a more streamlined look, Chris recommends forgoing trim. "It lends a clean look with less visual clutter," the architect 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.

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.
