40' Container Office

Forty feet of insulated, finished, climate-controlled office space — with the power, windows, and electrical to run a full crew from a single location. The 40ft is built for operations that don't slow down and sites that need a real command point.


Every unit is built from a one-trip steel container, fully framed, sprayed with closed-cell foam, and finished with heavy-duty vinyl flooring. Six LED lights, ten outlets, four large windows with welded burglar bars, a fire-rated steel door, and an 18,000 BTU mini-split that handles the full length — all included in the base build. Delivered in your color, ready to plug in and work.

Design and Planning

We create a customized plan for your project, including layout, modifications and features.

Build and Modification

Our team completes the construction and all requested upgrades with careful quality checks.

Delivery and Setup

We deliver your container to your location and make sure it is placed safely and ready to use.

FAQ

Frequently Asked Questions

  • How quickly can I get my container?

    Local deliveries for empty boxes are delivered within 1 to 3 days. For shipping container offices and custom modifications, the lead time varies depending on the specifications of your project. 

  • Do I have to pay before delivery?

    For custom container builds and shipping container office conversions, we require a 50% deposit up front.  The balance is paid upon completion of the project.

  • Can I choose between new and used containers?

    For empty containers for storage and other uses, we offer both brand-new and quality used containers, inspected for structural integrity and weather resistance.


    For shipping container modifications and office builds, we exclusively use one-trip containers to ensure the best longevity of your project. 

  • What types of modifications do you offer?

    If you can dream it, we can build it. From roll-up doors and windows to insulation, electrical, shelving, and custom paint, our team can build exactly what you need.


    We can join multiple containers together, trim a 20' down to a 10', or any other number of complex modifications. 

  • How much does delivery cost?

    Delivery rates vary by location and distance from the nearest hub. We always provide an all-inclusive quote with no hidden fees.

  • Can you deliver to my site if space is tight?

    Yes. Our team will discuss access requirements in advance and use the appropriate truck and equipment for your site. We have experienced delivery drivers on staff that can deliver even in tight spaces. We will discuss all the options with you during the buying process.
