Portable Hotels by Contained in Australia

These 20-foot shipping containers have been repurposed into luxurious hotel rooms by the Australian-based firm Contained. The portable structures have the unique ability to travel almost anywhere. Each container easily opens, flips out, and unfolds into an individual hotel room that opens up to the surrounding landscape, wherever that may be. Since its creation, Contained has designed amazing escapes in various locations including a winery in Victoria, a secret location on an island in the Sydney Harbor, and a wilderness retreat in Queensland.

Flophouze Hotel in Round Top, Texas

The interiors are clad with sustainably harvested wood from their own farm in upstate New York, reclaimed lumber from across the U.S., and windows that have been salvaged from a school in Philadelphia that was slated for demolition. Artifacts acquired from Matt White's travels across the globe adorn each Houze, making them unique from one another.

ContainHotel in Czechia

This year-round ski and yoga resort was built from recycled shipping containers. The minimalist design helps integrate the structure into its mountainside setting. The staggered construction allows most units to have a generous terrace space with stunning views of the Caucasus Mountains.
