Why the 40ft Office and Storage Container Combo Works
Most job sites need both an office and a place to lock up tools and materials. The traditional solution is two separate containers, two deliveries, and two spots on your site plan. The 40ft combo eliminates that problem.
Your crew gets a finished workspace on one end. The other end stores equipment, materials, documents, or inventory behind heavy-duty cargo doors. Both sections sit at ground level. No stairs. No ramps. No wasted space between units.
This layout is the same configuration used by contractors, utility crews, and project managers across the country. FCMS has provided storage solutions in Northern Colorado for over 40 years. We back every unit with professional delivery using our own drivers.
Stop paying for two containers when one does both jobs. The 40ft mobile office storage combo gives you a climate-controlled office and a locked storage area in a single unit. One delivery. One footprint. Two essential functions.
The office section spans 16 feet with insulation, HVAC, lighting, electrical outlets, and finished walls. The remaining 24 feet of the container serves as secure, weatherproof storage with standard double cargo doors. A steel partition wall separates the two sections.
Fort Collins Mobile Storage delivers this unit across Colorado, Wyoming, and Nebraska from our 12-acre facility in Fort Collins.

Office Section: 16 Feet of Finished Workspace
The office portion occupies 16 feet of the container’s length. That gives you roughly 128 square feet of usable floor space. Here is what the office section includes:
- 2-inch closed-cell spray foam insulation (approximately R-10.5 value)
- HVAC unit rated at 12,000 to 18,500 BTU for heating and cooling
- 100-amp electrical service panel with 240V entrance
- Interior LED overhead lighting across the full office ceiling
- Multiple electrical outlets spaced for desks, computers, and equipment
- 50-amp generator inlet for off-grid power capability
- Finished interior wall panels, easy to clean and built for job site conditions
- Commercial-grade vinyl flooring rated for heavy foot traffic
- One 36-inch steel personnel door with deadbolt and security bar
- One or two steel-framed windows (approximately 32″ x 36″) with security bars
- Exterior LED floodlight for nighttime visibility
The 128 sq ft office layout fits two to four people comfortably. Add desks, filing cabinets, plan tables, and a whiteboard, and you have a fully functional field office.
Storage Section: 24 Feet of Secure, Weatherproof Space
The storage portion occupies the remaining 24 feet of the container. This section stays unfinished to maximize load capacity and flexibility. Features include:
- Standard double cargo doors at the end of the container for wide-access loading
- Steel partition wall separating storage from the office section
- CORTEN steel floor, walls, and ceiling rated wind-tight and water-tight
- Forklift-compatible entry through the full-width cargo doors
- Lockable door hardware for independent access to the storage area
The 24-foot storage section provides roughly 192 square feet of floor space. That is enough room for pallets of materials, power tools, site signage, safety equipment, or seasonal inventory. The double cargo doors open the full width of the container. Forklifts and pallet jacks roll in without clearance issues.

Use Cases for 40ft Office and Storage Containers
The combo layout solves a specific problem. You need workspace and storage in one location without doubling your footprint or budget. Here are the most common buyers.
General contractors and construction managers. The office side becomes your field headquarters for blueprints, permits, and crew meetings. The storage side locks up power tools, PPE, and materials overnight. One unit covers both needs at a single delivery cost.
Utility and telecom crews. Field teams working on infrastructure projects need a planning workspace and a place to secure specialized equipment. The combo keeps both within steps of each other.
Agricultural operations. Farms and ranches use the office for seasonal admin work, billing, and crew coordination. The storage side holds feed, parts, chemicals, or harvest equipment. The steel construction keeps rodents and weather out.
Event and festival organizers. The office manages logistics, ticketing, and vendor coordination. The storage section holds signage, tents, AV equipment, and supplies. After the event, the whole unit ships to the next venue.
Disaster relief and emergency response. Agencies deploy the combo as a field command post with integrated supply storage. Generator power keeps it running off-grid.
Churches, nonprofits, and schools. Organizations add affordable admin space and secure storage to their property without a permanent construction project or foundation work.

How FCMS Compares to Standard Office Trailers
Traditional office trailers sit on a raised chassis. They need stairs or a ramp, level blocking, and often a crane for placement. Container-based ground-level offices (GLOs) skip all of that.
The 40ft combo sits directly on the ground. A roll-back truck delivers and places it in one move. Your crew walks in at grade level, which reduces trip-and-fall risk and meets accessibility goals. The CORTEN steel shell is stronger than trailer siding. The ISO frame handles stacking and relocation by crane or forklift.
Sites that rotate crews or move between projects benefit most. The combo container travels easier and costs less to relocate than a trailer.
Delivery Across Colorado, Wyoming, and Nebraska
We deliver from 311 N US Highway 287 in Fort Collins, CO. Our service area covers the full Front Range, mountain communities, southern Wyoming, and western Nebraska.
A 40ft combo requires a level surface that supports approximately 8,000 to 10,000 lbs. You also need roughly 100 feet of straight-line clearance and 14 feet of overhead clearance for the delivery truck. Our drivers handle placement. No crane needed.

Frequently Asked Questions
What is the office and storage split in this 40ft container?
The standard configuration provides 16 feet of finished office space and 24 feet of unfinished storage space. A steel partition wall separates the two sections. Contact us to discuss custom split options if your project requires a different layout.
Can I access the storage area without going through the office?
Yes. The storage section has its own double cargo doors at the end of the container. You can load and unload storage independently from the office entrance. The two sections have separate access points.
What power source does this unit need?
The office section requires a 240V electrical connection. The unit also includes a 50-amp generator inlet for sites without grid power. The storage section does not require a separate power connection.
How is the 40ft combo delivered?
We use a roll-back or tilt-bed truck. The driver places the container directly on the ground at your site. You need a level surface, 100 feet of straight clearance, and 14 feet of overhead clearance. No crane or forklift is required for delivery.
Can I relocate the container later?
Yes. The unit retains its ISO corner castings and forklift pockets. A roll-back truck, crane, or heavy-capacity forklift can move it to a new site. Many buyers relocate the combo between projects over several years.
Do I need a permit?
Requirements vary by jurisdiction. Some cities and counties treat container offices as temporary structures that do not need a permit. Others require a placement or building permit. Check with your local building department before scheduling delivery.
How does the 40ft combo compare to buying two separate containers?
The combo saves money on delivery (one trip instead of two), saves site space (one footprint instead of two), and keeps your workspace and storage side by side. A separate 20ft office and 20ft storage container would cost more and take twice the site area.
Is the storage section climate-controlled?
No. The storage section is unfinished CORTEN steel, rated wind-tight and water-tight. It protects contents from rain, snow, and wind but does not include insulation or HVAC. The office section is the only climate-controlled area.
Can I add shelving, partition walls, or other upgrades?
Contact us about customization options. Common requests include interior shelving in the storage section, additional electrical outlets, extra windows, and partition walls within the office area.
