The Salsa Box, by Portland, Oregon-based Shelter Wise, offers yet another take on very small-scale living. Completed earlier this year, and available to purchase from US$22,500, this particular tiny house stands out from the growing crowd with a build quality and interior layout that makes living in a 9 sq m (96 sq ft) space seem not only technically possible, but perhaps even appealing.

The Salsa Box was first conceived as a demonstration model to show workshop students what's involved in building a tiny house, and from there evolved into a purchasable product. As standard, the dwelling measures 3.5 x 2.4 m (12 x 8 ft), but there are also larger 4.8 m (16 ft), 5.4 m (18 ft), and 6 m (20 ft) long versions available.

It's built using FSC (or Forest Stewardship Council – an international non-profit organization that promotes responsible forest management) certified wood and sports a metal roof, along with efficient low-emissivity (Low-E) windows, which offer more insulation than standard windows.

Judging from the photos available, the Salsa Box looks finished to a high standard and comes equipped with a queen-sized bed that sleeps two, plus amenities such as an electrical hookup, a flushing toilet, an electric hot water heater, a combined shower and mini-tub, and a kitchenette.

There's a fair amount of storage too – though this has subsequently reduced usable floorspace to an absolute minimum and it's a very tight squeeze. Indeed, as is the case with all similarly-sized homes, living in the Salsa Box full time would require some pretty big lifestyle changes.

Shelter Wise informed Gizmag that the Salsa Box can optionally be rigged to go fully off-grid. The flushing toilet can be swapped out for a composting toilet, solar power can be added, and a water catchment system can be affixed to the roof.

The Salsa Box doesn't need a permit to tow as it can fit on a standard trailer, and if required, it can also be modified to rest on foundations.
