CASE STUDY
Notable Local Container Projects

Shelton's Auto Masters Two Bathrooms and Office Space
At the height of the Covid-19 pandemic, Shelton's Auto Masters, a full service automotive repair shop in Kahului Maui, approached Allison Shipping Containers, Inc. to build a shipping container office unit with two bathrooms to enable them to have clean and comfortable COVID compliant restroom facilities on Maui.
While Shelton's Auto Masters didn't have immediate plans to relocate the restrooms, it made sense for the business to invest in a space that could be transported to a new location in the future should the need arise.

Backyard Office
A young couple suddenly required to work at home during the COVID epidemic asked Allison Shipping Containers, Inc. to build them a backyard office. They needed a place to work efficiently from home and didn't have enough room in their house.
They wanted the office to be 8' x 15' feet so they didn't need to worry about getting a permit from the City and County of Honolulu. (You're allowed to have a 120 square foot storage shed on residential property without getting a permit.)
The couple wanted to keep costs down by doing a lot of the work themselves, so we started with a 40' used shipping container, cut it to 15 feet, end-capped it, and installed a sliding glass door and two windows to provide the space with lots of natural interior light. We welded on the interior studs and they added insulation, hung the drywall and did all of the interior finishing work themselves.
The final project looks great!
