If interested in owning a tiny house, you could purchase one from a specialist firm, but for handy types happy to roll up their sleeves, PAD (Portland Alternative Dwellings) has collaborated with Shelter Wise to offer plans for its Bunk Box. On the small side, even for a tiny house, this model looks best suited as a weekender, second home, or perhaps a guest home.

The Bunk Box is based on a 16 ft (4.8 m)-long double-axle trailer. There's 125 sq ft (11.61 sq m) of floorspace on the ground floor and another 72 sq ft (6.6 sq m) in the sleeping loft.

The interior decor is pretty odd as it isn't finished with wood paneling or drywall, leaving the framing exposed. According to PAD, this adds an extra 7 in (17.78 cm) in width of usable space. Since there's no insulation stuffed in the walls, the firm instead wrapped the Bunk Box in 2 in (5.08 cm) of closed-cell foam insulation.

Most of the ground floor is taken up by the living area. Further into the home lies a kitchenette and bathroom with shower and toilet. There's also a seating area, desk and wardrobe. The sleeping loft is accessed by ladder and has enough room for a double bed. Overall, the inside looks snug but livable.

The roof of the Bunk Box features a pair of skylights and the example home pictured is clad in Shou Sugi Ban-treated wood, which is all the rage with tiny houses lately and for good reason: the ancient Japanese art of burning wood increases its durability and protects it from fire and termites, and the like.

Still, since this is a DIY tiny house, it's obviously up to the builder to choose what siding they want.

Plans for the Bunk Box will set you back US$99. For that, PAD promises detailed construction drawings, basic electrical plans, material details and other suggestions – such as a composting toilet if you'd like to make it run off-the-grid, for example.

For those looking for something a lot more roomy, another recent tiny house we covered that offers the plans available for sale is the Basecamp.
