"It was rundown, dark, and divided," recalls Masaaki of his first impression of the warehouse, the ground floor of a multistory apartment building. But after some thought, Masaaki, a Japanese-born architect, and Esther, an artist from Minorca, realized that owning the combined 2,700 square feet would allow them to headquarter Mas-aqui, the architecture and design firm they were planning to start, on-site. They bought the property and within months transformed it into a bright, modern live/work space.

The dining area features a PH5 pendant by Poul Henningsen for Louis Poulsen, a T12 table by Hay, and Møller Model 77 side chairs. A 1960s rocking chair by Vladimir Kagan sets off the living area.

NOEM, a Barcelona–based architecture firm, created a metal-clad house for a young client just outside Madrid. It’s raised 12 feet off the ground to offer better views of the landscape, lending it "the futuristic feeling that it just landed," says Pol Guiu, one of NOEM’s cofounders.

Sited on a cramped corner lot in Manhattan Beach, California, this midcentury bungalow was renovated and enlarged with a 1,000-square-foot addition to create a total of 1,986 square feet of functional space for owners Alison and Jeff Goad and their three children. Culver City–based practice Edward Ogosta Architecture demolished and remodeled parts of the existing house to include a larger master bedroom and a new bedroom, bathroom, and powder room. The project also included updates to the two existing bedrooms, the laundry room, and garage.

“A building can have far greater impact than the space it stands in.”—William Carpenter, architect and resident

The Jorgensen's Menlo Park home is a model of green design with features that are smart for everyone to consider. "Every project is different, but there are some universal things that will apply from project to project," says Feldman about designing a green home. "The first—and most obvious thing—is to always try to build less, to have a smaller house and be smart about how the rooms are designed and oriented so that you can get by with less space. Smart design will lead to a smaller building, but it won't feel smaller."

New zoning allowed for a zero-lot-line structure, but required a public storefront, which Carpenter uses as an art gallery.

One family in Seattle, Washington, looked past a sloping landscape and saw the opportunity to build their dream home. Resembling a modern-day metal treehouse, the Hale and Edmonds residence is nestled within the edges of a wooded park. The house’s exterior of paneled grey is perfectly balanced against the accent of the orange frame, proving that there’s a chance for subtlety with the bright color.

"Shane enjoys both cooking and entertaining so we maximized the counter space to make meal prep and hosting easy," Priftaj says. "It was also very important that the kitchen include a gas grill so he could quickly and conveniently grill without having to climb up five flights of stairs to use the bbq on the patio." Priftaj selected high-gloss acrylic white cabinets from bulthaup's b3 line with an aluminum backsplash and b3 prism drawer system to keep things tidy. A Wolf hood and gas cooktop with chargrill give Carslake the flexibility he desired for indoor grilling. The counters are polished white quartz.

The sunken living room is just one of many grade changes inside the structure. “We were adamant that we didn’t want something domestic,” says Andrew. “We wanted something surprising, that was hyper-animated, and that, when you moved through it, changed all the time.” The sofa, designed by the couple and Levenbetts, is upholstered in cotton velvet. The Habibi side tables are by Philipp Mainzer for e15, the fireplace tools by Fort Standard, and the doors by Fleetwood.

The 260-square-foot Hytte module features tall ceilings of up to nearly 12 feet. Multiple windows fill the interior with natural light and frame views of the outdoors.

Stepstone's narrow concrete pavers add a graphic touch to the garden.

When designer Hilton Carter furnished the industrial-style Baltimore apartment and work studio he shares with his wife Fiona, their dog Charlie and two cats Zoe and Isabella, he created a wondrous indoor woodland that offers all the benefits of being outdoors without leaving home.

The colors used in the interior were inspired by the surrounding landscape. The kitchen island is clad in solid timber fluting crafted from durable plantation-grown iroko with with a granite top. “The green-blue-brown color of the granite benchtops very much reminded me of the colors of the water in the nearby harbor of Tutakaka,” says architect Belinda George.

A custom sofa was installed on the far side of the bathroom for even more space to relax.

"A well-performing house extension facing south on a small inner-city block built in rammed earth is not easy to achieve," said Welsch. "However, in this challenge was our opportunity: We decided that our extension will curl around to capture the sun, creating a communal courtyard and allowing the occupants to look at their own house rather than a paling fence."

Rian and Melissa Jorgensen's 2 Bar House in Menlo Park boasts all the usual green design suspects: energy-efficient lighting, good insulation, renewable material finishes, radiant heat, and the roof is pre-wired for future PV panels. Executed by Feldman Architecture, the house requires only natural lighting during the day which keeps energy costs way down. Still, the most stunning aspect of the green design is the living roof planted with succulents, aloe, viviums, and ice plants. "I'm absolutely glad that we did it," says Melissa. "It turned out so well and I really enjoy sitting up there and taking advantage of it as much as I can. It's very peaceful." Read more about this total remodel here.

The Lais designed their house to be theirs forever. As such, they were able to make design moves that made sense for themselves but that wouldn't have high resale value, like the Japanese-style master bathroom in the middle of the second floor instead of off of the master bedroom. The traditional setup features bath stools from Muji for washing off.

The built-in bench that borders the cantilevered bed features two storage drawers and a hatch that accesses an additional storage compartment.

The crisp white kitchen features appliances built into the cabinetry and marble countertops.

San Francisco’s modernists were faced with the issue of building within a firmly established stylistic tradition—think bay windows and gingerbread. Henry Hill’s 1947 renovation of a 1908 Victorian tucked away on an alley in historic Russian Hill provides a remarkable response to the dilemma.
