Bunk Box


Bunk Box is a highly customizable tiny house plan. Available in digital format only.


The Bunk Box is a unique modern tiny house design that leaves the wall framing and electrical exposed on the interior. This stylish detail has a great benefit to the homeowner: rather than covering the framing with drywall or wood paneling, they can use – and feel – an extra seven inches of width stretch out all the way to the exterior sheathing. Space is precious in a tiny home, so why let conventional construction methods hide what you could be using?

Built on a 16 foot trailer, the Bunk Box is 125 square feet on the main floor, with an additional 72 square feet in the sleeping loft. Tall people rejoice! A flat roof and exposed roof framing mean extra head height in the loft: three feet, nine inches allow free movement throughout the loft without bonking your forehead. Two large skylights connect residents with sunny days and starry nights. An optional, second door (as shown) and six windows also open the house to sunlight, great views and fresh air.

Shelter Wise used their signature attention to energy efficiency and their years of tiny house construction experience on this special design. The construction details page in this plan set is extensive. Since the insulation is not inside the framing, the house is wrapped in 2″ of closed cell foam to eliminate almost all of the thermal breaks and outperform conventional insulation packages. Even the floor assembly is thermally separated from the steel trailer, which all too often means cold feet in the winter, even when insulated in the standard fashion. Like a well-insulated thermos, this design keeps your warm spaces warm and cool spaces cool.

The house as shown is sided with burnt wood cedar siding, also known as shou sugi ban, but any siding can be used. This exposed, modern tiny house design means that the materials themselves, inside and out, give the house its signature style. That offers tremendous potential to the do-it-yourselfer to create a look and feel that’s uniquely their own.

The Bunk Box is a great house for an individual, and couples or families could easily revise the design into a 20, 24 or 28 foot house with some added care around window and door placement. Whether it’s a guest room, bunk house, office or full-time tiny home, the Bunk Box is like no other tiny house out there.
