Its debut model, the Roving, looks a good balance between size, price and amenities, and costs US$19,884 for the Semi-DIY option, which includes a basic shell, doors and trailer.

The Roving sits on a trailer for easy towing and is nicely finished with cedar siding, low-E (low emissivity/energy efficient) windows and a metal roof. Inside, wall framing, house wrap and window tape help keep out the chill, while the door and walls are made from reclaimed wood and the floor is made from cork.

The Roving's snug 154 sq ft (14 sq m) of floorspace is divided between a living area, kitchen (with sink, refrigerator and electric cooktop), closet, and bathroom (with shower and composting toilet). Two lofts contain a sleeping area with double bed and some additional storage space, but are accessed by ladder, so you'll need to be physically able to live in one of these.
