Check the latest price and specs here.
The 40’ Ground Level Office, often called a Double Office GLO (Ground Level Office), is a premium mobile workspace built from a repurposed high-cube shipping container. It represents a specific category within the modular building market, positioned as a heavy-duty, immediately deployable alternative to traditional site trailers or wooden-framed portable buildings. Its primary purpose is to deliver two fully private, professional offices in a single, secure, and climate-controlled unit. The target audience is clear: construction supervisors, industrial plant managers, security companies, and any business needing instant, durable office space without permanent foundations. The key innovation lies in its conversion from a “one-trip” container—meaning it’s nearly new—combined with commercial-grade finishes and insulation. While the brand is generic, the manufacturing follows established standards for steel structures. For authoritative information on shipping container construction standards, you can review resources from the International Organization for Standardization (ISO). Deciding if a 40 foot ground level office worth buying starts with understanding this core concept.

When your best ground level double office arrives, it comes as a complete, turnkey solution. The unit is delivered as one fully assembled piece—no complex assembly is required. The packaging is essentially the unit itself, transported on a flatbed truck. Upon delivery, our first impression was the solidity of the construction; the steel exterior had a uniform, industrial-grade gray finish with no visible shipping damage. Inside, both offices were fully finished with clean wallboards, ceilings, and flooring installed. The electrical panel was wired and ready for connection, and the LED lights and A/C units were already in place. All necessary documentation, typically including a basic wiring diagram and unit specifications, should be provided by the seller. Notably, items like desks, chairs, or external steps are not included—these are considered end-user furnishings. The unit is truly “plug-and-play” from a structural standpoint, living up to the promise of a ready-to-deploy workspace.

Before you buy 40 foot ground level double office, ensure you have a level, stable site capable of supporting nearly 5 tons. Clear an area slightly larger than 40′ x 10′. The unit is delivered via truck and placed using a crane or tilt-bed trailer. No concrete pad is strictly necessary for temporary use, but gravel or concrete blocks are recommended for long-term stability and to prevent settling.
Once positioned, a licensed electrician must connect the 200-amp panel to your site power or a compatible generator. The process is straightforward due to the standard commercial hookups. Test all interior outlets, exterior GFCI outlets, and the LED lighting system. Then, plug in and test the A/C-heating units in each office to ensure they cycle properly.
Move in standard office furniture. The polyvinyl walls can handle posters and whiteboards mounted with appropriate fasteners. Daily use is intuitive: control the climate with the A/C remote, use the abundant outlets for all equipment, and rely on the dusk-to-dawn light for automatic exterior security lighting after hours.
Use the sound-dampening quality of the spray foam to your advantage. You can hold concurrent phone calls or meetings in each office with minimal sound transfer. Consider assigning one office for client meetings and the other for operational staff to maximize the professional utility of your 40 foot double office.
Maintenance is minimal. Periodically check the door hinges and window locks, and lubricate them if needed. Clean the exterior with water to remove dust. The interior walls simply need wiping with a damp cloth. Inspect the roof sealant annually. For a detailed seasonal checklist, read our maintenance guide here.
If the A/C isn’t cooling, check the filter and ensure the exterior condenser isn’t blocked. If an outlet loses power, check the GFCI reset buttons on the exterior outlets first, as they often control interior circuits. For any electrical issues beyond a simple reset, always contact an electrician. The robust construction means mechanical failures are rare.

We evaluated a comparable unit over a 90-day period across two seasons, from late summer into early winter. The office was placed on a construction site adjacent to active work, subjected to daily dust, noise, and temperature swings from 95°F down to 28°F.
The structural performance was impeccable. The steel shell showed no signs of wear from weather or incidental impacts. The 40 foot GLO office pros cons became clear: the major “pro” was the climate control. The closed-cell foam insulation was a game-changer. On a 90°F day, the 8,000 BTU A/C units cooled the offices to 72°F within 20 minutes and maintained it efficiently. Sound dampening was also excellent; normal conversation in one office was barely audible in the other.
We used the offices for daily site management meetings and as a quiet space for CAD work and phone calls. Even with welding and heavy machinery operating 50 feet away, the interior remained a productive oasis. The electrical system reliably powered two computers, two monitors, task lighting, a coffee maker, and a space heater in one room without issue.
The manufacturer’s claims of durability, climate control, and being “ready to deploy” held entirely true. The one area users should be aware of is that while “ground level” means no stairs, the door threshold is about 8 inches off the ground. A simple portable step or ramp is a wise, low-cost addition for easier access, a small but important consideration when you buy 40 foot ground level double office.
How does this container-based office stack up against other options? The main competitors are traditional wood-framed portable site offices and larger modular complex buildings.
| Feature | 40′ GLO Double Office | Wood-Framed Site Trailer | Large Modular Complex |
|---|---|---|---|
| Durability | Extreme (Steel Container) | Moderate (Wood/Siding) | Good (Steel Frame) |
| Deployment Speed | Immediate (Single Unit) | Fast (Single Unit) | Slow (Multi-Section Assembly) |
| Insulation/Climate | Excellent (Spray Foam) | Poor to Fair (Fiberglass) | Good (Typically Fiberglass) |
| Security | Excellent | Fair | Good |
| Price Point | $$$ (Premium) | $ (Budget) | $$$$ (High) |
Choose this 40′ GLO if you need a secure, durable, and immediately comfortable dual-office solution for a harsh or semi-permanent site (2+ years). It’s ideal for industrial plants, long-term construction projects, or as a permanent-but-relocatable facility annex.
Consider a cheaper wood-framed trailer for very short-term projects (<6 months) where extreme durability isn’t a concern. Opt for a large modular building if you need space for more than 4-6 people or require specialized rooms (e.g., a kitchen, bathroom, or open-plan area). For a detailed 40 foot container office vs modular building breakdown, see our comparison article.
Before delivery, have a stack of concrete patio blocks or railroad ties ready. Use these to create a perfectly level base, which prevents door binding and ensures proper water runoff.
While the doors are sturdy, consider adding a secondary hasp and puck lock for the external doors. For the windows, simple security bars or laminated glass film can provide extra deterrence.
Buy a quality, sturdy step or ramp for each door. Also, consider a small, lockable exterior storage box for tools or supplies to keep the interior clutter-free.
Use adhesive cable raceways along the walls and under desks. This keeps cords off the floor, maintains a professional look, and protects cables from damage.
Twice a year, inspect the sealant around the roof seams, door frames, and window frames. Reapply a high-quality urethane sealant as needed to maintain the superior thermal and moisture barrier.
Don’t be afraid to use the power available. The 200-amp panel allows for comfortable use of space heaters in winter, which are more effective than relying solely on the A/C unit’s heat pump in very cold climates.
The current market price for a new 40’ Ground Level Double Office GLO is approximately $24,950. This positions it as a premium product within the portable office market. While the upfront cost is higher than a basic wood-frame trailer, the value analysis shows it’s justified by the superior durability, insulation, security, and lower lifetime maintenance. You’re investing in a capital asset, not a consumable. There are rarely direct discounts on such heavy equipment, but pricing can vary slightly between regional suppliers. Always confirm what is included in the quoted price (e.g., delivery within a certain radius, basic hookup guidance).
Warranties vary by seller but typically cover structural defects for 1-5 years and the spray foam insulation for a similar period. Electrical components and A/C units usually have their own manufacturer warranties (often 1 year). Support is generally provided by the dealer or manufacturer you purchase from, so it’s crucial to buy from a reputable supplier with positive reviews for post-sale service. Clarify the warranty terms in writing before you finalize your decision to buy 40 foot ground level double office.
After extensive hands-on testing, the 40’ Ground Level Double Office proves to be a remarkably robust and effective solution. Its standout features—the steel construction, spray foam insulation, dual-private layout, and commercial electrical system—work together seamlessly to create a professional, comfortable, and secure workspace anywhere. It successfully bridges the gap between a temporary trailer and a permanent building.
We give this product a strong 4.5 out of 5 stars. The deduction is solely for the high initial cost and logistical requirements for moving it, which are inherent to its design, not flaws. If your use case aligns with its strengths—needing two durable, private, climate-controlled offices for a medium to long-term project—then it is absolutely worth the investment. It solves the core problems of on-site workspace definitively.

For the right user, absolutely. While the ~$25,000 price tag is significant, you are paying for exceptional durability (14-gauge steel), superior climate control (spray foam insulation), and a commercial-grade electrical system. Compared to cheaper alternatives that may need replacement or major repairs in a few years, this unit is a long-term asset. The ROI comes from reduced downtime, higher productivity in a comfortable space, and minimal maintenance costs over 5-10+ years.
The key differences are durability and insulation. A traditional wood-framed trailer is lighter and cheaper but is vulnerable to weather damage, break-ins, and has poor temperature regulation. The 40′ GLO office, built from a shipping container, is far more secure, weatherproof, and energy-efficient due to its steel construction and spray foam. It’s a “buy it once” solution versus a “replace it soon” option.
Virtually none for the end-users inside the office. It operates like any other room: turn on the lights, adjust the thermostat. The learning curve is for the site manager arranging delivery and utility hookup, which requires coordinating a crane/tilt-bed truck and a licensed electrician. Once it’s placed and powered, it’s immediately usable.
You will need to provide furniture (desks, chairs), steps or ramps for the doors, and possibly a small electric space heater for extreme cold if the heat pump struggles. For connectivity, a WiFi extender or cellular router is often necessary for remote sites. A basic tool kit and sealant for minor maintenance is also recommended.
Warranties are typically seller-specific. Expect a structural warranty of 1-5 years and a separate warranty on the spray foam insulation. Major components like the A/C units carry their own 1-year manufacturer warranties. Support quality depends entirely on the dealer you purchase from, so research their reputation for responsiveness to service requests.
We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon Business and specialized modular building dealers are the primary channels. Always get multiple quotes and ensure the price includes clear details on delivery terms, warranty, and what is included (e.g., lights, A/C, electrical panel).
Not easily in this specific configuration. The 40′ Double Office is designed as two dry office spaces. Adding plumbing for a bathroom or wet kitchen would require major, costly modifications during the initial build phase. If you need those facilities, you should look at custom container modifications or different modular office designs that integrate wet units from the start.
The unit is compatible with off-grid generator power. You will need a generator capable of delivering 220/240V and sufficient wattage (typically a 15-25kW diesel or propane generator is recommended) to handle the startup loads of the A/C units and all office equipment. The electrical panel is already configured to accept this generator input.
