What Is a Modified Container?

A Standard Container, Built Out for Your Needs

A modified shipping container starts with the same Corten steel ISO structure, the most durable weatherproof portable structure available, and adds the features that turn it into a functional space. Personnel doors, windows, insulation, electrical, HVAC, custom paint, shelving, flooring: modifications can be as simple or as comprehensive as the project requires. The base unit can be ordered in different grades. See our container condition guide, and our rent vs buy guide if you are weighing how to pay for it.

In Washington, modified containers serve a wide range of purposes. Construction companies need quick-deploy job site offices. Farm and acreage owners need lockable, weather-resistant equipment rooms. Rural property owners want a cabin base that holds up outdoors. Businesses want branded field offices that can be moved between sites.

Tell us what you need the container to do and where you need to put it. We will help you find the right starting unit and the right configuration for your property and budget.

Why a Container Instead of Traditional Construction?

  • Significantly faster than a stick-built structure
  • Built on a shell that is already weatherproof and secure
  • Relocatable, not permanently tied to one site
  • Practical for remote sites a construction crew struggles to reach
  • No foundation required for most temporary uses
  • Handles what Washington weather brings, including the long wet season and the winter storms that ride in on it

Washington Applications

How Washington Customers Use Modified Containers

Puget Sound Job Site and Alley Access Offices

Contractors, remodelers and restoration crews from Everett to Olympia use modified containers as the lockup and the office on site. The constraint here is the approach rather than the haul, so we plan the alley, the overhead wire and the grade before anything is cut, and on a tight lot two modified 20ft units often solve what one 40ft never will.

Olympic Peninsula, Kitsap and Island Builds

Out here the shortest line on the map is rarely the shortest drive. Some sets make sense on a Washington State Ferries sailing, plenty make more sense around the south end over the Narrows or north over the Hood Canal Bridge. We route first and quote a date second, and we specify for a site that stays damp well into summer.

Yakima Valley, Wenatchee and Columbia Basin Field Offices

Packing houses, wineries, hay and potato operations and the data centre builds around Quincy all need a dry, lockable room where there is no building. Orchard geometry decides placement more than acreage does: row spacing, low trellis wire, overhead frost fans and irrigation laterals sit exactly where a truck wants to swing, so we ask which end of the block it goes on.

Inland Northwest and Palouse Farm Builds

Wheat operations, ranches and timber ground north and east of Spokane need a building where there is none, and the ground out there is some of the easiest in the state to set on. Two things shape the schedule: the 279 mile run over Snoqualmie Pass, and the seasonal load limits county road departments post during the spring thaw.

The Process

How a Modified Container Order Works

1

Tell Us What You Need

Describe the intended use, the property location, any access constraints, the timeline, and the budget range. The more detail you share, the better we can match you to the right container and configuration.

2

We Recommend a Configuration

We recommend the base container, size and grade, the modifications that suit the use case, and give you an all-in price including delivery to your Washington address.

3

Order Confirmed and Build Begins

Once the order is confirmed, modifications are completed before delivery. Lead time on a modified container runs longer than a standard unit, typically 2 to 4 weeks depending on scope and the current build schedule.

4

Delivered to Your Property

The finished container arrives on a tilt-bed truck, the same as a standard delivery, ready to use or close to it depending on the configuration.

Tell Us About Your Project

The more detail you share, the better we can help. Modified containers are priced by project, so there is no standard price list.

FAQ

Modified Container Questions

Personnel doors, windows, roll-up doors, partition walls, electrical with lighting and outlets, HVAC, insulation, interior finishes, shelving and exterior paint. Work is done by Container One before the unit ships, so what arrives is finished rather than a shell you then have to hire out.
From your drawings or your sketch, not from a catalogue page. Tell us the base size, what goes in it, whether it needs power and climate control, and where it is going in Washington. A modified unit is priced as a build, so the number depends on the work rather than on a list price.
The same approach any container of that size needs, about 100 feet of straight, level run for a 40ft base and at least 14 feet of overhead clearance, plus somewhere for the power to come from if the build is electrified. Confirm the service at the site before you order, because a generator changes the running cost.
Longer than a stock container, because the work happens before the unit ships. Delivery of a stock unit runs typically 1 to 2 weeks for greater Seattle, the Eastside, the South Sound, the North Sound and southwest Washington, and 2 to 3 weeks for the Olympic Peninsula, the coast, island addresses and everything over the Cascade crest, including Yakima, Wenatchee, the Columbia Basin and Spokane A build adds fabrication time on top of that, and we give you the real date once the drawings are agreed rather than a placeholder up front.
