Version.3 is designed to take temperatures of -50 °C (-58 °F) in its stride, and also packs a number of other benefits over its predecessor, including increased interior space and decreased weight.

Version.3 measures 4.9 m (16 ft) long, and comprises an interior floorspace of 9 sq m (97 sq ft). The towable tiny home is part-built using sustainable and reclaimed materials, including Forest Stewardship Certified wood and repurposed metal mesh. The interior is lit with LED lighting and features a custom Murphy Bed, and a kitchen area which includes a double stove, sink, and small fridge freezer. The diminutive home also includes a small shower and composting toilet.

A mirrored wall is installed in a bid to lend a feeling of increased space, and weight was saved wherever possible. For example, a lightweight countertop lends the appearance of a full slab of concrete but is actually a foam board with a concrete top, while curtains were used to hide storage spaces instead of using cupboards.

Version.3 features Panasonic Vacuum Insulated Panel (VIP)-based insulation, which boasts a claimed R-Value of R30 per 1.27 cm (0.5-in). The VIPs insulate the floor and roof to an impressive R68, while the walls are insulated to R38 (for those unfamiliar with R-Value, it's a measure of thermal resistance by which insulation can be judged).
