Nestled within a forest clearing near the Argentinian city of Córdoba, this 2,153-square-foot house named "La Negrita" is designed to exist in harmony with nature. Designed by Córdoba–based Morini Arquitectos, the house first reveals itself as a black corrugated wall in the middle of the woodlands. "The house is totally introverted [and] mysterious towards the street and extroverted towards the interior," says Morini.

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.

“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.

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 countertops in the kitchen are a mix of quartz surfaces and custom and salvaged stainless steel. "We use the kitchen all of the time, it turned out really nice," says Melissa. "It's very open, certainly one of the central focuses of the house, and is fun for entertaining."
