With this in mind, Brighton, Colorado-based tiny house firm Walker Wilderness Enterprises recently completed the aptly-named Container Tiny House which can be configured to run on or off-the-grid.

The Container Tiny House is based on a large 40 ft (12 m)-long high cube container and has a single door and several operable windows installed. The interior comprises a total floorspace of 320 sq ft (29 sq m).

We've written at length about our appreciation for shipping container-based architecture, but their lack of insulation poses real concerns – just try walking inside a container on a hot day and it's obvious that it would need significant modification to make it suitable for full-time living. A few windows simply won't cut it.

To address this, Walker Wilderness Enterprises says it has framed, drywalled, and insulated the container home with 3 - 4 in (7.62 - 10.16 cm) of closed cell spray foam insulation in an attempt to keep the heat and cold at bay.
