What Is a Modified Container?

A Standard Container, Built Out for Your Needs

A modified shipping container starts with the same Cor-Ten steel ISO structure and adds 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 your project requires. The base unit can be ordered in different grades (see our container condition guide). If you are weighing financing options, see our rent vs buy guide.

A modified container can be set up as a job site office, a lockable equipment room, a cabin base, or a branded field office that can be moved between sites.

Describe what the container needs to do and where it will be placed. A Container One sales representative prepares the quote for your Colorado property.

Why Container vs. Traditional Construction?

  • ✓ Built on a steel shell with lockable doors
  • ✓ Can be relocated: not permanently tied to site
  • ✓ A formal foundation is not always required for temporary use

Colorado Applications

Uses for Modified Containers

Front Range Job Site Offices

A modified 20ft or 40ft container, insulated and climate-controlled, can serve as a lockable on-site workspace for superintendents and project managers. Fully outfitted office builds can be discussed with a Container One sales representative.

Western Slope Hunting & Fishing Cabins

A modified high cube can serve as a base camp on hunting land or a fishing property on the Western Slope, in the mountains, or on a ranch in Eastern Colorado. Insulation, HVAC, bunk beds, an electrical package, and a lockable structure can be added, which helps on properties that are hard to reach with a construction crew.

Ranch Offices: Eastern Plains & Western Slope

A ranch or agricultural operation can use a modified container as a field office, an equipment maintenance bay, or a break room. A roll-up door added on the side or end turns a 40ft container into a shop bay for small equipment maintenance.

Mountain Retreat & Cabin Conversions

A modified container can serve as a cabin on a mountain property, such as in Summit, Grand, Pitkin, or Gunnison County.

The Process

How a Modified Container Order Works

1

Tell Us What You Need

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

2

A Configuration and Quote

A Container One sales representative recommends the base container (size, grade), the modifications for your use case, and a written quote for your Colorado address.

3

Order Confirmed & Build Begins

Once your order is confirmed, modifications are completed before delivery. Modified containers take longer than a standard unit, depending on the scope of work and the current build schedule.

4

Delivered to Your Colorado Property

The finished modified container is delivered to your site on a tilt-bed truck: just like a standard container delivery, but the unit arrives ready to use (or nearly so, 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. There is no standard price list.

FAQ

Modified Container Questions

Modified container lead times are longer than a standard unit. You will get a timeline when you discuss your project.
Potentially yes, depending on what the container is being used for and your municipality's rules. A modified container used as a temporary job site office may be treated like a construction trailer in some municipalities. A container used as a habitable structure (cabin, office with full occupancy) or placed permanently may require a permit. Check with your local building or planning department before ordering a container for structural use.
Yes, with an insulation package and a heating system. Spray foam insulation also seals penetrations against condensation and air infiltration. A mini-split both heats and cools. Describe the site elevation and the use when you discuss your project.
Some Colorado municipalities allow shipping containers to be used as accessory dwelling units (ADUs) or guest structures on residential properties, subject to zoning approval, building permits, and compliance with applicable codes. Consult your local zoning and building departments before planning a container ADU.
