Why Rent a 40ft Office and Storage Container
Renting two separate containers costs more and takes more space. The 40ft combo solves both problems in a single unit. Your crew gets a finished office on one end and locked storage on the other.
Rental terms start at one month. We prorate the first month from your delivery date. You pay monthly until you request pickup. There is no long-term commitment.
This is the same combo configuration that contractors and project managers use across the country. FCMS has delivered storage solutions in Northern Colorado for over 40 years. We own our trucks and handle placement with our own drivers.
Office Section: 16 Feet of Finished Workspace
The office portion occupies 16 feet of the container. That gives your team roughly 128 sq ft of usable floor space. Here is what the office section includes:
- 2-inch closed-cell spray foam insulation (approximately R-10.5)
- 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 and equipment
- 50-amp generator inlet for off-grid power capability
- Finished interior wall panels, durable and easy to clean
- 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 with desks, filing cabinets, and a plan table.
Storage Section: 24 Feet of Locked, Weatherproof Space
The remaining 24 feet stays unfinished to maximize load capacity. Features include:
- Standard double cargo doors at the end for wide-access loading
- Steel partition wall separating storage from the office
- 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 storage access
The storage section provides roughly 192 sq ft of floor space. That handles pallets, power tools, safety gear, signage, or seasonal inventory. The double cargo doors open the full container width. Forklifts and pallet jacks roll in without clearance issues.

Use Cases for a 40ft Office and Storage Container
The combo rental serves teams that need workspace and secure storage at the same location for a defined period.
General contractors. Rent a field office with built-in tool storage for the life of a build. Return the unit at project closeout. One rental replaces two containers.
Utility and infrastructure crews. Field teams working on road, pipeline, or telecom projects get a planning workspace and gear storage within steps of each other.
Event and festival organizers. The office side manages logistics and vendor coordination. The storage side holds signage, AV equipment, and supplies. The rental ends when the event wraps.
Agricultural operations. Farms rent for harvest season or planting cycles. The office handles billing and crew coordination. The storage side secures equipment, parts, or chemicals.
Emergency and disaster response. Agencies deploy a command post with integrated supply storage. Generator power keeps it running off-grid. Rental terms flex with relief timelines.
Schools and churches. Organizations add temporary admin space and secure storage during building projects or seasonal surges without a permanent construction commitment.

How a Rental Combo Compares to an Office Trailer
Traditional office trailers sit on a raised chassis. They need stairs, ramp access, level blocking, and often a crane for placement. Ground-level offices (GLOs) skip all of that.
The 40ft combo sits on the ground. A roll-back truck delivers and places it in one move. Your crew walks in at grade level. That reduces trip-and-fall risk. The CORTEN steel shell is stronger than trailer siding. The ISO frame handles relocation by truck, crane, or forklift.
At the end of your rental, we pick it up the same way.
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.
The 40ft combo needs a level surface that supports 8,000 to 10,000 lbs. You also need about 100 feet of straight-line clearance and 14 feet overhead for the delivery truck. Our drivers handle placement. No crane needed.
When your rental period ends, we schedule pickup at your convenience.

Frequently Asked Questions
What is the minimum rental period?
One month. We prorate the first month from your delivery date. Billing runs on a monthly cycle until you request pickup.
What is the office and storage split?
The standard layout gives you 16 feet of finished office and 24 feet of unfinished storage. A steel partition wall separates the two sections. Contact us if you need a custom split.
Can I access storage without going through the office?
Yes. The storage section has its own double cargo doors at the container’s end. You load and unload storage independently from the office entrance.
What power source does this unit need?
The office section requires a 240V electrical connection. A 50-amp generator inlet is included for off-grid sites. The storage section does not need separate power.
How is the 40ft combo delivered and picked up?
We use a roll-back or tilt-bed truck for both delivery and pickup. You need a level surface, 100 feet of straight clearance, and 14 feet overhead. No crane or forklift required.
Can I relocate the unit during my rental?
Yes. Contact us to arrange relocation. A roll-back truck or heavy forklift can move the unit on your site or to a new location.
Do I need a permit?
Requirements vary by jurisdiction. Some areas treat container offices as temporary structures. Others require a placement or building permit. Check with your local building department.
Is the storage section climate-controlled?
No. The storage section is unfinished CORTEN steel rated wind-tight and water-tight. It protects contents from weather but does not include insulation or HVAC.
How does renting the combo compare to renting two containers?
The combo saves money (one rental, not two), saves site space (one footprint, not two), and keeps workspace and storage side by side. It costs less than two separate rentals.
