Peter lined the pass-through’s opening with plywood.

The first story Alexi photographed for us was Separate Boite Equal in Montreal.

A series of levels gives the house a sense of separation between the main rooms.

Separated only by large expanses of glass, the interior and exterior landscape flow together.

One of three separate seating areas.

The house is divided in two: on the left, the main house consists of an expansive kitchen, living, and dining space, plus sleeping accommodations. On the right, a smaller structure holds a sauna, shower, and ski wax room. The house’s length is oriented along an east/west axis to maximize strong southern light and provide views of an aspen grove.

A view from the kitchen back into Atherton's wing of the house, separated by the front door and walkway.

The inner dimple, not far from the front door, separates the entrance from the living space.

A seamless sliding door by CS For Doors—accented by Mockett hardware—separates the master bedroom from the living room and doubles as a backdrop for a projector.

A translucent Polygal corridor separates Small and Medium.

One of the children's rooms, equal parts clean-lined and playful.

The living room, which opens directly to an ipe deck, is separated from the dining area by a central spiral staircase.

The architect chose glass to segment space because it takes up fewer centimeters than constructed walls, thus helping the room feel larger. Curtains can be drawn closed for privacy. The bed and side table are custom, while the pendant light is from Exclusive Lighting.

The office, which is a single-level separate unit, boasts Ikea desks and a signed work by Gilbert and George (friends of the couple).

The backyard is one of this home’s best features. With a lot that nearly equals the square footage of the home itself, there was plenty of room to play with landscaping.

Glass doors make for an easy transition from the deck to the kitchen, where a painting by Erin Rachel Hudak hangs behind a round Saarinen dining table.

A steel-framed, bi-fold door system by Skyrange Engineering separates the edge of the house from the outdoor area.

The view from the kitchen is as lively as it is light, taking in the dining area, tiny courtyard garden, and the separate office building backed by the jumble of old buildings to the rear. The rustic dining chairs are by Börge Mogensen from Karl Andersson & Söner.

The living space and bedrooms are separated by two small courtyards. Linda Taalman reclines in a small, inflatable wading pool in the home's "firecourt," facing south toward the desert.

Only a set of sliding doors separates the kids’ room from the master bedroom in a Toronto, Ontario, home. When the time is right, there's a track inlaid in the ceiling for a four-panel bifold wall to divide the space into two private rooms for the children. Read the whole story here.

Surviving a natural disaster can be hard on your body—particularly if you need to walk long distances. To be as efficient as possible, you want to stock up on high-calorie, lightweight foods with long shelf lives like dried fruit, nuts and nut butters, crackers, and energy and protein bars. Canned food and MREs (meals-ready-to-eat) are also a good idea, but make sure that you have the means to open them by also packing a can opener or only purchasing pop-top cans.

After seven minutes, the length of time it takes to produce the proper amount of char, the boards are separated.

Equal parts home and office, the studio retreat boasts expansive views of Lyttelton Harbor.

Garcetti and Wakeland enjoy a quiet afternoon, sitting in what used to be two separate bedrooms. By removing a wall, the space now serves as an office and den, divided only by sliding doors.

“The vibe feels cozy even though the living room is quite grand,” Adler says. He made the room divider out of concrete and integrated the sofa with the step. Lee Jofa fabric covers the dining chairs and the pendants are vintage.

The home is carefully sited between tall trees in a pine forest and is split into almost equal areas of indoor and outdoor living space.

Kurokawa and Fishman's son Danny Fishman-Engel enjoys time away from the city by studying magic tricks in his bedroom. Sliding slatted doors separate the asymmetrical downstairs spaces.

The structure's unique H-shape layout is designed to separate living and sleeping areas, and for maximum natural light.

The windows/doors open to allow both the interior and exterior spaces to work together or separately creating equal spaces and allowing the maximum amount of sunlight in.

The glass walls that separate the living area from the courtyard fully retract to allow a smooth passage between the two.

A terrace covered by a pergola runs past the private volume (which contains three bedrooms of equal size and a bathroom on the ground floor) to the covered patio, and down the stairs to the pool.

A glassed-in walkway connects the open-plan living areas to a separate bedroom wing.

A series of plywood panels separate the large common area of the cabin from the smaller private areas. They slide open to reveal the sleeping area, outfitted with custom bunk beds.
