Camp Box- Your ADU and Storage Discount Outlet
Camp Box can build anything that you can dream and would love to build you a Frank Gehry Disney Concert Hall or Bilbao Museum but one-off projects are extremely expensive as we must reinvent every inch. Otherwise-specialization, mass production and economies of scale are the only way any business can offer economical products. So we have set models that we build hundreds of and we like to avoid special custom changes as it slows the process and runs the price up, beyond simple door and window placement or optional items. Delivery of buildings is also time-consuming, so it is simpler to site build -usually one day for flat tops and day and a half for loft units with meager travel cost added.
Because building permits here are difficult and expensive, and every property is allowed one accessory structure of 120 square feet and up to 15 feet tall, with the current shortage of affordable units it would seem logical for every house to have an accessory structure. Plastic storage buildings and steel containers do not maximize allowed space or are too large and are extremely hard to modify into useable space. The brilliance of single wall construction makes our wood units easy to modify and move on roadways and the 1011 8 by 15 maximizes allowable footage and height. Our hope is the someday have only the 1011 that we only build and build one a day always the same. DPP does not allow hard wiring hence our wiring is a free bonus that is not guaranteed in any fashion.
—–Customer Relations section is very important reading in working with the Camp Box system and philosophy. We require a minimum $600 deposit prior to traveling to jobsite; full payment puts you front of list; balance due prior to crew leaving site.
We do not make site visits as it is pointless; if you would like to meet us and see one of our units you can visit us at our shop in Waiahole 9 to 10 or weekends.

Required Additional Charges-
Unless you have a trailer and can pick up your unit at our shop, travel cost must be added from our travel map of $100 to $600.
A base/foundation is also required in some form. We normally dry lay/loose lay 8 concrete CMU block as a most economical option at 8 inches up for $50 on relatively flat ground. To go up two layer or 16 inches is $100 or if on slope. Two layers is less stable and three layers to 24 inches will require double block piers for stability, thus using 6 per spot and 48 total and $300. Optional added concrete can be priced.

It has a plywood floor ready to paint as well as T1-11 siding to provide a smooth interior a board and batten exterior-All UNPAINTED. We provide 4 outlets and 2 lights as well as an indoor sink and outdoor shower, with connections for a toilet and water heater- while these items are not allowed on a DPP accessory structure they can be removed easily if someone complains.
All of our production models are single wall construction meaning that the plywood siding provides the interior and exterior surface just like all older Hawaiian homes. Horizontal interior supports as well as the exterior battens create a web structural support. If you are in an elevated extremely high wind location and do not want wall vibration or desire insulation or sheetrock later and want a secondary interior flat(1 ½) or standard(3 ½) stud wall framing it can be added for $900 to any unit.
All units can be either right face or left face door and sink, shower and toilet canbe placed in any corner with your special-order unit.
Model 711- Modern Side Slope Studio w/ loft- $4,000 unpainted (delivery extra)
Utilizing mass production, we can make more progressive designs that are more complicated through our production process while still keeping cost down by minimizing waste and streamlining task. The modern roof slope allows for a generous loft/attic space that can expand comfortably to an 8 by 8 area (add$100) while staying well within Hawaii road regulations for transporting. Again, we include a utility sink, toilet hookup, and outdoor shower as well as two switched lights and five outlets. The water lines are fed by connecting to a gardenhose and unit is piped ready to connect to a tankless gas water heater by the sink. Power supply by simple extension cord. The short wall left of sink is ideal for adding base and wall cabinets and counters. There is soffit venting around the overhang of the white thermoplastic roof membrane with a life expectancy of 30 to 40 years. These wood frame structures, like any home, are extremely easy to work on if windows or doors need adding or flooring and paint, whereas plastic or steel containers are extremely challenging to modify. Stylish modern designs common accepted board and batten exterior make this unit an eye-pleasing addition to any property and hopefully acceptable for all watchful neighbors.
All units can be either right face or left face door and sink, shower and toilet can be placed in any corner with your special-order unit.
Delivery– Can range from $100 to more than $500 depending on distance and site maneuverability and terrain. Units are normally set on a double stack of 8-inch concrete blocks, so 16 inches roughly off the ground. We normally also do 2 stacks in the center for a total of 16 blocks on level ground for a total of $50 for your foundation. We provide straps that are integrated into the floor system that you can join with any standard ratchet strap unit and a ground anchor to secure the unit to the ground as they are light-weight and can shift in high winds. As we are always striving for efficiency and affordability to combat our affordable housing crisis we will gladly allow you to deliver the unit yourself with the use of our trailer with a deposit and adequate collateral.
Model- 1011 Traditional Rear Angle Roof w/ 2 lofts –$4,000 unpainted( del. ext)

The finished bottom base floor ends up around 93 inches by 187 inches which totals 120.77 square feet and the doorway threshold deducts another 76 square inches which should be near the 120 sq foot max., however our entire business model is designed around us avoiding any an all red tape, conflicts and time consuming conversations, so therefore any responsibility for complying with any Hawaii rules and regulations of any nature or kind fall solely on you or the property owner and building purchaser. As always, across our great country, our governments are complaint driven so by conferring with your neighbors ahead of time and ensuring that they will be comfortable prior is good planning towards avoiding silly arguments over minuscule details. Remember also that DPP rules for accessory structures is to be 5 feet off of each property line.
Our goal is to provide fast and efficient buildings so we encourage smart planning, cooperation and flexibility so that no time is wasted and all are happy.
