A 24-by24-foot Cor-ten-clad pavilion tops the three-story addition.

In the kitchen area and throughout the home, Mads Odgård, shown here, and Mette Lyng Hansen mixed Odgård’s pieces, such as the Odgård kettle for Raadvad and custom table, with Ikea basics and the Workshop pendant lamp by Louis Poulsen.

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.

The Cobb Haus, a wood-sided, 700-square-foot cabin in Cobb, California, features a large wood deck surrounded by towering trees.

Graphic and pastel textiles adorn a collection of modern chairs and sofas in the downstairs sitting room. Warm-gray floorboards extend throughout the whole lower level for a fresh, modern look.

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

From urban-dwellers to empty-nesters, many are now embracing the movement toward smaller, more sensible living. Bosch's new line of 24" kitchen appliances is designed to help them save space without downsizing on style.

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

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.

Bosch's compact kitchen line, which includes an electric and gas cooktop, wall oven, and refrigerator, as well as an 18" dishwasher, is particularly well-suited for city apartments and secondary hangouts, like basements and guesthouses.

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.

Tasked with creating a multi-use guest pavilion on a relatively small Northern California vineyard lot that could also host sit down dinners for up to 60 people, designers at Anderson Architects started by asking the key questions: “Where should it be within the property?” “How much floor area do we need for a 60 person dinner?” “How much volume do we need for a basketball court?” “We also always tell ourselves to look at the landscape first, let it dominate and lead it through. The building took the form of a large Napa Valley barn.

Walsh and Strongin's living room strikes a more rustic note.

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 dresser at the other end of the bedroom is by Paul Frankl; the plywood lounge chair is by Ib Kofod-Larsen; and the huge cork-based floor lamp is from Reeves Antiques.

A pair of mid-century perches by Kofod-Larsen sit beneath a print by Andy Warhol in an upstairs bedroom.

Together, Bosch's sleek 24" kitchen and laundry suites address the trend toward smaller living by extending modern, European-style design to even the closest quarters.

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.”
