FAQs
The Most Suitable Container Sizes for Container Offices
When choosing a conex box office, size matters. The most common options are 10-foot, 20-foot, and 40-foot containers, where high-cube variants (9.5 ft tall) offer extra vertical space.
Here’s how each size stacks up:
- 10-foot container: Ideal for solo workspaces or small storage needs. 8’x8’x10, it fits a desk, chair, and basic supplies. Perfect for guard shacks, ticket booths, or pop-up kiosks, its compact footprint makes it easy to fit on tight sites or urban lots.
- 20-foot container: The goldilocks option for small teams. Provides ~160 sq ft of space for 2–4 people, workstations, and equipment. Transportable and versatile for construction sites, remote offices, or mobile classrooms.
- 40-foot container: Best for larger teams or multi-use spaces. Offers ~320 sq ft, allowing for partitioned areas (office + storage, meeting rooms, etc.). High-cube versions add headroom for HVAC systems, lofted storage, or just a more open feel.
If you need more space, connect multiple containers side-by-side or stack them for modular office complexes that look like this.
Many companies offer custom fabrication to join containers seamlessly, so we can have open-plan offices, conference rooms, or even multi-story buildings.
General Specifications of Conex Box Offices
Conex box offices can come from converted shipping containers or be built in such a way during the construction process. Nonetheless, their general specs are like these:
Material
Corten steel walls (14-gauge) and reinforced corner posts for structural strength.
Doors
Double cargo doors for wide access or single personnel doors with windows for everyday entry.
Flooring
Marine-grade plywood, vinyl, or anti-slip coatings. Some offices use raised floors for wiring and HVAC ducts.
Customizations
Pre-wired electrical systems, insulation, HVAC, windows, shelving, and built-in desks or storage.
Weight Capacity
Up to 55,000–67,200 lbs (depending on size and condition).
Finish
Exterior paint is usually marine-grade for weather resistance; interiors can be finished in drywall, paneling, or left as painted steel.
Apart from the above, most conex box offices include climate control, overhead lighting, power outlets, and lockable storage.
If you want to use the offices indefinitely, you can anchor them to concrete foundations or elevate them on piers or blocks for ventilation and flood protection.
Protective Levels of Conex Box Offices
Fireproof
While standard steel containers aren’t fully fireproof, they still have a high degree of fire resistance that can protect you and your belongings.
To improve such degrees of fire resistance, you can use the following solutions:
- Fire-resistant insulation: Gypsum board, mineral wool, or rockwool panels resist flame and slow heat transfer.
- Flame-retardant coatings: Intumescent paint expands under heat, creating a protective barrier.
- Smoke detectors and extinguishers: Required for compliance with workplace safety codes.
- Fire-rated doors and windows: For extra protection in high-risk settings.
While the above are effective for preventing fire, you still must avoid storing flammable materials inside and ensure all electrical systems are up to code to reduce fire risk.
Bulletproof
Although they can handle some significant punishment, conex box offices (like shipping containers) aren’t inherently bulletproof.
Because of that, conex box offices must use some upgrades to improve their imperviousness against bullet-caused damage.
Reinforced steel plating
Weld some additional steel layers or ballistic panels to walls and doors that can stop handgun and rifle-grade bullets from piercing inside.
Ballistic-grade windows
Polycarbonate layers or laminated glass rated for specific calibers, where the protection improves against higher calibers if the window material is thicker.
Blast-resistant designs
If you want to use the container office for projects with high security requirements, you can add blast-resistant doors, walls, and anchoring systems.
Rodent-proof
Although shipping containers are naturally rodent-resistant thanks to their steel construction, gaps around doors, vents, or utility penetrations can still let pests in.
As a result, you must do the following to keep pests away from your office:
- Install door sweeps and vent covers to block entry points.
- Elevate the container on blocks or piers to prevent burrowing underneath.
- Seal all penetrations (for wiring, plumbing, etc.) with silicone caulk or expanding foam.
- Regular inspections and pest control treatments keep mice, rats, and insects at bay.
How to Transport Conex Box Offices to Intended Locations
You can use the same transportation methods for delivering shipping containers with conex box offices:
Truck
Flatbed or tilt-bed trucks are popular for most local deliveries.
Crane
Essential for placing containers in tight spaces, on rooftops, or for stacking multi-story complexes.
Rail or Ship
If you want to move the office cross-country or internationally, you can ship it via rail or cargo vessel.
Key Tips:
- Secure permits for oversized or heavy loads, especially for 40-foot or high-cube units.
- Hire experienced transport companies to avoid damage during loading, transit, or placement.
- For modular complexes, disassemble sections and transport them individually, then reassemble on-site.
- Prepare your site in advance: ensure access for trucks or cranes, and have a level, stable foundation ready.
Conex Box Types That Can’t Be Converted into Offices
Not all shipping containers are created equal, and when it comes to these containers, you should never, EVER, use them as foundations for conex box offices:
Damaged containers
Units with corroded walls, bent frames, or compromised floors are unsafe for occupancy.
Refrigerated (reefer) containers
Their thick insulation and built-in machinery take up valuable interior space and complicate modifications.
Tank containers
Tank containers don’t exactly make the best (or logical) working environment, so they’re out of the question.
Open-top or flat rack containers
Lack of roofs or walls makes them unsuitable for enclosed offices. They’re also impractical for modifications to other uses.
How Long Can Conex Box Offices Last?
With proper maintenance, a conex box office can last 25–30 years or more, depending on factors like:
Climate
Coastal or industrial areas with high humidity or pollution may cause container offices to corrode faster (if they don’t have protective layers).
Maintenance
Repaint every 3–5 years, replace door seals and insulation as needed, and keep the roof clear of debris to avoid water pooling.
Foundation
Elevating the container on blocks or piers prevents rust from ground moisture, especially that from rain and storms.
Usage
Heavy traffic or frequent moves may shorten lifespan, while stationary, well-maintained units last longer.
Things You Can Store Inside Conex Box Offices
Work items and materials inside the conex box offices aren’t that different from regular offices:
- Tools and equipment: Construction gear, landscaping tools, safety equipment.
- Documents: Filing cabinets for records, blueprints, or sensitive paperwork.
- Inventory: Retail stock, event supplies, or promotional materials.
- Electronics: Servers, printers, AV systems, and networking gear (with climate control).
- Personal items: Lockers for staff, uniforms, or break room supplies.
- First aid or emergency kits: For remote or hazardous sites.
Avoid: Perishables (unless refrigerated), hazardous chemicals, or anything prohibited by local regulations.
Should I Rent or Buy Conex Box Offices?
Rent If:
- You need a temporary setup (e.g., a 6-month project, event, or seasonal business).
- Budget is tight upfront, or you want to avoid long-term commitments.
- You’re testing the concept before committing to a purchase.
- You want the flexibility to upgrade, downsize, or relocate easily.
Buy If:
- You need long-term or permanent space.
- Customizations are required (e.g., plumbing, HVAC, built-in furniture).
- Tax benefits (depreciation) matter for your business.
- You want full control over design and modifications.
Cost Comparison: Renting costs $100–$300/month for a basic 20-foot office, while buying ranges from $2,000–$6,000 for a used 20-foot container (plus modification costs). High-cube or custom units cost more.
Leasing is another option, offering lower monthly payments with the option to buy at the end of the term.
Can You Add Feature Customizations to Conex Box Offices?
Absolutely! One of the biggest draws of Conex box offices is their customizability. Popular upgrades include:
- Interior layouts: Partition walls for private offices, meeting rooms, or break areas; drop ceilings; or lofted storage.
- Utilities: Solar panels, plumbing for sinks or restrooms, Wi-Fi boosters, and data cabling.
- Aesthetics: Branded exteriors, custom paint, vinyl flooring, glass doors, or murals.
- Security: Cameras, keypad entry, alarm systems, reinforced locks, and security bars for windows.
- Accessibility: Ramps, wide doors, and ADA-compliant restrooms.
- Climate control: HVAC units, ceiling fans, or additional insulation for comfort in any weather.
- Furniture: Built-in desks, shelving, lockers, or kitchenettes.
Work with a fabricator or container modification specialist to ensure your upgrades meet local building codes and safety standards.
Can the Conex Box Offices Be Sent to My Location?
Yes, Conex box offices can be delivered almost anywhere, from urban job sites to remote oil fields. Logistics depend on:
- Accessibility: Can a truck, trailer, or crane reach your site? Check for low bridges, narrow roads, or soft ground.
- Permits: Some areas require permits for temporary or permanent structures, especially for larger or stacked units.
- Delivery Costs: Range from $500–$2,000+, depending on distance, container size, and site conditions.
- Site Prep: Clear and level the area before delivery. For permanent installations, prepare a concrete pad or piers.
Providers like USA Containers, Conexwest, and Tradecorp USA offer nationwide delivery and can coordinate crane or forklift placement if needed.
What Are the Suitable Insulation Materials for Conex Box Offices?
Insulation is vital for comfort, energy efficiency, and preventing condensation. Top options include:
Spray Foam
Expands to fill gaps, blocks moisture, and offers high R-value (~$1.50/sq ft). Excellent for sealing every nook and cranny, but more expensive.
Fiberglass Batts
Affordable, easy to install, but requires vapor barriers and careful sealing (~$0.50/sq ft). Can absorb moisture if not protected.
Rigid Foam Boards
Easy to cut and install, moisture-resistant, and available in various thicknesses (~$0.75/sq ft). Great for walls and ceilings.
Reflective Insulation
Aluminum foil-faced insulation reflects radiant heat, ideal for hot climates (~$0.30/sq ft). Often used in combination with other materials.
Mineral Wool/Rockwool
Fire-resistant and excellent for soundproofing, but heavier and more costly.
Cellulose Insulation
Eco-friendly, made from recycled paper, and good for sound dampening.
Pair insulation with proper HVAC systems (window units, split systems, or central AC) for year-round comfort. Don’t forget to insulate doors and windows, and use double-glazed glass for better thermal performance.
