Ethan Schussler built his first tree house at 12 years old. His tree house in Sandpoint, Idaho, sits 30 feet above the ground and can be accessed by an "elevator" consisting of a bicycle that, when pedaled, ascends a pulley system to the top.

Airstream’s Flying Cloud 30FB Office travel trailer includes a designated workspace in the back corner.

The design team restored the existing wood beams, giving nod to the home’s former rustic life, while introducing big windows, white walls, and clean lines.

Bay Point Landing offers cabin and Airstream accommodations, RV sites, a communal clubhouse, an indoor saltwater pool, an event hall, a private beach—and plenty of open spaces for surfing, whale watching, crabbing, fishing, or hiking.

The upper floor of one of the cabins features a wood-burning stove, beanbag chairs, and a hanging paper lantern.

The backyard evokes the serenity of a Japanese Zen garden with a beautiful leaning tree and a shou sugi ban shed.

Milan saw the launch of wrong.london, an offshoot of HAY that's run by creative director Sebastian Wrong. The lighting-focused division released these veneered-oak lampshades, dubbed 30degree, among other designs.

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

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.

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

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.

For a cost-conscious 2,000-square-foot renovation located 30 minutes outside of Austin, Texas, architect Nick Deaver took a look around for inspiration. He spied galvanized metal cladding on the region’s sheds and co-opted the inexpensive, resilient material for his own design.

Terreo Studio aimed to make this seven-unit apartment complex look “unrecognizable, so it stays a mystery from the outside.” From the white stone facades, through the interior marble and complimentary soft palette of the furnishings, to the open floor plan that meanders between courtyards, the architects took cues from Grecian architecture: Natural materials are used in abundance to create a structure that embraces the environment.

For cosmetics company CO/CO, Tatabi created the branding and packaging design. Taking a cue from nature, the simple packaging almost transforms the beauty goods to food products.

See Arch restored the exterior fireplace wall and painted it a deep blue hue to match the repainted blue timber cladding.

ESCAPE Tampa Bay Village is currently comprised of ten tiny homes situated on individual lots. Due to popular demand, the village will soon expand with an additional 30 units.

While a two-story structure did not meet the zoning code, Richard Neutra bypassed that via his design of a "gloriette," an outdoor room flanked by aluminum louvers. Those panels shelter the home against the harsh desert elements and were recreated as part of the five-year restoration of Richard Neutra's original design. Photo: Tim Street-Porter

The Airstream Haus’s interior is minimalist, but comfortable, boasting a fully functional kitchen and queen-size bed that doubles as a couch.

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.

Kai and Téa brush their teeth in the upstairs bathroom shared by all. “We went with the 1950s thing—a family bathroom,” explains Blatt. The sinks are by Kohler.

The Airstream Haus, parked in Ojai, California. August says that when your dwelling is small, it’s important to make the most of outdoor space.

“I really believe buildings are part of a city as an organism.”—William Carpenter, architect and resident

The renovation revealed a 30-foot-deep well beneath the bedroom, which the team half-jokingly considered turning into a fish tank. Instead, they opted for a simple bedroom with plenty of built-in storage.
