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.

The extensive use of natural wood on nearly every surface makes the inside of The Barn feel like an extension of the landscape outside.

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.

The entryway leads into the living room, and a low wall hides the staircase that leads to the lower level from view.

Designed by Belgium architectural studio OYO Architects, this 1,883-square-foot family residence in Maldegem, East Flanders, was conceived with a single green roof that meets the grass at ground level. The concrete base of the structure supports a lightweight timber frame, which was assembled in a local warehouse before being mounted on site. Different plants are grown on the green roof throughout the seasons.

This is the entrance to my backyard. To the left is my bedroom and to the right is my garage. We have 3 fruit trees and we used to have healthy grass but my husky has wore out my grass. I used to sit under tree during summer and relax but its not so relacing anymore. Id like a mini outdoor kitchen to entertain maybe to the left?

Though this home is close to downtown Minneapolis, it sits on a quiet, 3.77-acre piece of land. When you approach the brick home, it immediately becomes clear that it’s a Frank Lloyd Wright-designed home—thanks to its wing-like shape and Cherokee Red-painted steps.

Completed in 1946, the Booth House was originally built for an advertising executive and his wife before becoming a rental property in 1955 for the architectural photographer Robert Damora, and architect Sirkka Damora. The Damoras later purchased the home and have lived there ever since. Now 93 years old, Sirkka has been seeking a new owner for this piece of architectural history. Litigation over the title means that the Booth House could face being torn down—so its buyer will also be its rescuer.
