The Bunk Box Tiny House: Industrial Chic Meets Natural Warmth
The Bunk Box is a unique tiny house 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. The exposed 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.
What the Plans Include
- Plans for a house that is 16’-8” long, 8.5′ feet wide, and 13’-6” tall, including a 1’-10.5” tall trailer. Note: the trailer is 16 feet long, and the extra eight inches of length come from the exterior foam.
- Detailed interior and exterior elevation drawings for all sides
- Trailer connection details
- Wall framing elevations
- Roof framing plans
- Cross sections of wall, roof and floor
- Details for corners, windows, the door
- Suggested materials list for siding and framing
- Product details on the sink, shower, tankless water heater, bath fan, and composting toilet used in the photos shown.
- A basic electrical plan
- A thoroughly energy efficient design. These plans include details for a unique, full R7 thermally broken floor assembly that could effectively host radiant floor heat (most floors would lose radiant heat warmth through contact with the metal trailer), but please note that radiant heat floor products or installation instructions are not a part of these plans.
These plans do not include plumbing diagrams or exterior finish materials. The plans do not include instructions on how to assemble the stainless steel custom bent shower. The shower dimensions are listed. Shelter Wise hired a local metal fabricator to execute the shower and would suggest you do the same to achieve the same look. These plans are a license to build ONE house, and contain all of the essential nuts and bolts to get you a solid, extremely energy-efficient tiny home that is completely customizable to your tastes.
When choosing a trailer for this house, Shelter Wise recommends 7,000 lb axles each, for a 14,000 lb total carrying capacity. The trailer will still carry at 10,000 lb GVWR (Gross vehicle weight rating) but will travel better and safer with higher rated axles. Iron Eagle Trailers builds our favorite tiny house trailers out there, and Derin from Shelter Wise and Dee from PAD even helped them design their trailers to be perfect for tiny homes. Tell them PAD sent you, and you’ll get $50 off your order.
With all of our plans, we recommend a copy of Go House Go, our how-to manual for building a tiny house on wheels. It’s the book Dee wished existed when she built her little house, and she wrote it to save everybody else all the time and trouble that she went through to figure out how to build smart and safe.
