Jobsite offices without the stairs.
XCaliber’s Mobile / Ground-Level Offices provide durable, secure, climate-controlled workspace for construction sites, industrial facilities, commercial operations, and other portable workspace needs. Built in Texas from steel shipping containers and set directly on the ground, so your crew walks in the door instead of up a set of trailer steps.
A Ground-Level Office (GLO) is a portable workspace built inside a steel shipping container and positioned directly at ground level. Because the unit sits on the ground or on blocking rather than on a wheeled chassis, it provides workspace without the elevated entry, stairs, or platforms of a traditional mobile office trailer.
XCaliber’s Mobile Offices can provide dedicated workspace on their own or combine office space with secure storage, a bathroom, and other features depending on the configuration. Whether you call it a Mobile Office, a Ground-Level Office, a Shipping Container Office, a Conex Office, or a Jobsite Office, you are describing the same product family: an XCaliber office container built for the jobsite.
The unit sits at ground level, so trailer stairs, ramps, or platforms are typically not required. Crews, visitors, and deliveries walk straight in.
Corrugated steel shipping container construction suited to construction sites, industrial facilities, and other demanding environments.
Delivered by truck and set in place where the workspace is needed. Our logistics team coordinates the delivery date and any site instructions with you.
Available HVAC, insulation, electrical, and lighting options keep the office usable through Texas summers and winter jobsites alike.
Workspace and lockable storage in a single unit, so tools, materials, or inventory stay secure a few steps from the desk.
It is still a shipping container. When the project wraps, the office moves to the next site by truck.
Steel walls, lockable doors, and available security features protect plans, equipment, and electronics after hours.
Every configuration below is built on a 10′, 20′, or 40′ steel shipping container and sold outright. Open a product to see photos, options, and delivered pricing for your ZIP code.

In under a minute: how a mobile office improves day-to-day work for a business or a crew. The examples below show where XCaliber customers put them to use.
A dedicated place to run the job: plans on the table, a door that locks, and air conditioning when the site is 100 degrees. The office sits at grade, so subs and inspectors walk straight in.
One container, two jobs. The office end handles paperwork and calls while the lockable storage bay keeps tools and materials secure and close.
A 10′ office at the gate gives security or a site clerk a climate-controlled post with sight lines to traffic and a place to log arrivals.
XCaliber builds scale houses in 10′, 20′, and 40′ lengths for truck scales and material yards, with operator windows positioned for the lane.
Give the crew a place out of the weather, or set up HR, safety, and payroll on a site that will run for months.

Both give a crew a place to work. The differences are structural: how you get in, what the unit sits on, and what it can carry with it. Read the full comparison: Mobile Office vs. Traditional On-Site Trailer.
| Feature | Ground-Level Container Office | Traditional Office Trailer |
|---|---|---|
| Entry | Ground level | Typically elevated |
| Stairs, platform, or ramp | Typically not required | Typically required |
| Chassis | None; sits on the ground or on blocking | Wheeled chassis with axles and hitch |
| Delivery and placement | Delivered by truck and set in place | Towed to site and leveled |

Renting an office trailer is easy to start and easy to keep paying for. Owning a ground-level container office turns a recurring line item into an asset you keep, relocate, and customize for the way your crews work.
| Feature | Buy a Ground-Level Office | Rent an Office Trailer |
|---|---|---|
| Ownership | You own the unit; it is an asset on your books | You pay monthly for as long as you need it and return it at the end |
| Cost over time | One-time purchase; financing options available for commercial buyers | Rent continues every month; long projects and repeat jobs add up |
| Time on site | No time limit; keep it through the whole project and the next one | Rental terms and minimums set by the rental company |
| Reuse | Relocate it to the next site or facility | Return it and rent again at the next site |
| Customization | Built to your spec: layout, storage, branding, windows, and finishes | Standard stock configuration; limited changes allowed |
| Exterior branding | Paint, signage, and branded exteriors available | Usually restricted by the rental company |
| Resale | Sell it when the need changes | No resale; no equity |
| Best for | Repeat projects, long deployments, and permanent facility needs | Very short-term needs where a standard unit will do |

A ground-level office is a portable workspace built inside a steel shipping container and set directly on the ground or on blocking, so there is no elevated entry. XCaliber builds them in 10′, 20′, and 40′ lengths as office-only, office + bathroom, and office + storage configurations.
A shipping container office is an ISO steel shipping container finished as a workspace with insulation, climate control, electrical, lighting, windows, and a personnel door. Ground-Level Office, Mobile Office, Conex Office, and Jobsite Office all describe this same product family.
Yes. Ground-level office describes where the unit sits (at grade, no stairs) and shipping container office describes what it is built from. XCaliber’s Mobile Offices are both.
XCaliber offices are built on 10′, 20′, and 40′ high-cube shipping containers. The 40′ office + storage units split the length between office and storage, for example 10′/30′ or 18′/22′.
HVAC and climate control are available on XCaliber offices, along with insulation, electrical, and lighting. Each product page lists the options for that configuration.
Yes. The Office + Storage configurations pair a finished office with a lockable storage bay in the same container, in 20′ and 40′ lengths.
Yes. The 20′ Mobile Office with Bathroom and the 40′ High-Cube Mobile Office with Bathroom include a private restroom built into the unit.
A ground-level office sits on the ground with no chassis, so entry is at grade and stairs or platforms are typically not required. A mobile office trailer rides on a wheeled chassis, sits elevated, and typically needs steps, skirting, and tie-downs. The comparison table above lists the structural differences.
Typically not. Because the office sits at ground level, crews, visitors, and deliveries walk straight in the door.
Yes. It is still a shipping container, so it can be loaded and moved to the next site by truck when the project ends.
Lead times depend on configuration and stock. In-stock units ship soonest; look for the Ready to Ship listing in the configurations above, or ask our sales team about current lead times for a built-to-order unit. Our guide to preparing for delivery covers what to have ready on site.
Yes. Layouts, finishes, storage splits, and features can be tailored through Custom Builds, and fleet buyers can order rental-grade or private-label units through Fleet Manufacturing. See Electricity & Shipping Containers for how electrical packages are set up.
Yes. The 10′ Mobile Office works as a guard shack or check-in station, and XCaliber builds dedicated scale houses in 10′, 20′, and 40′ lengths.
Construction (civil, commercial, and institutional), energy and oil & gas, industrial and manufacturing, utilities, equipment rental, railcar maintenance, and data center and power infrastructure projects all use ground-level offices as field offices, control rooms, gatehouses, and administrative space. Commercial Uses for Shipping Containers has more examples.
XCaliber sells ground-level offices; we do not offer rentals. Financing is available — see Financing Options. Renting vs. Buying a Shipping Container walks through the math.
Pricing depends on size, configuration, and delivery location. Each product page shows delivered pricing for your ZIP code; start with the configurations above. For what drives price, see How Much Does a Shipping Container Cost?
