A shipping container office is a durable, mobile workspace built from a standard ISO container (typically 20ft or 40ft) and finished with insulation, HVAC, electrical, lighting, windows, and doors. It’s ready to work in 5–10 days, costs 40–60% less than traditional construction, and can be relocated or resold when your project ends.
Whether you need a jobsite field office, farm workspace, backyard studio, or temporary admin space, we offer turnkey units ready to deploy or raw containers for DIY conversion. Start from $15,000 to buy; $800/month to rent.

Sizes & Configurations
20ft Container Office (~160 sq ft)
Best for: Site supervisor, small team, solo workspace, farm office
- External dimensions: 20′ × 8′ × 8’6″ (or 9’6″ High Cube)
- Internal usable space: ~150 sq ft
- Standard features: single A/C, basic electrical, 2–3 windows, one door
- Starting price (turnkey): ~$15,000–$35,000 depending on finish
40ft Container Office (~320 sq ft)

- Standard features: dual A/C, robust electrical panel, 4–6 windows, two doors
- Starting price (turnkey): ~$25,000–$75,000+ depending on finish & customization
High Cube Upgrade
Both 20ft and 40ft are available in High Cube (+12 inches of height = 9’6″ tall). Adds ~$2,000–$5,000 but provides noticeably more headroom and a less cramped feel.
Prefab “GLO” (Ground-Level Office)
Fully finished, factory-tested before delivery. Ready to plug in and work day one. Premium pricing (~$35k–$50k) but zero construction risk and known timeline.
The Combo Office + Storage Unit — Jobsite Hero Product
Perfect for contractors, construction PMs, and project managers.
Split a single 20ft or 40ft container with a partition wall: office workspace on one side, secure locked storage on the other. The office side has your climate control, power, and windows; the storage side remains climate-controlled, weatherproof, and accessible for tools, materials, and equipment.
Why this works on jobsites:
- One delivery, one footprint, no extra site footprint cost
- Your crew has a secure, comfortable field office and protected tool/material storage
- Lock the storage side when the office is unoccupied—no theft risk
- Relocate the entire unit as the project moves
Typical configuration:
- 20ft: ~100 sq ft office + ~60 sq ft locked storage
- 40ft: ~200 sq ft office + ~120 sq ft locked storage
Starting price: ~$20,000–$50,000 (depends on finish level and storage vs. office split ratio).
This is a game-changer if you already rent storage from us. One call for both needs.
Buy vs. Rent — How to Decide
Rent (~$800/month typical)
Best for:
- Short-term projects (under 18 months)
- Temporary needs (office during renovation, seasonal farm workspace)
- No maintenance/repair responsibility desired
- Flexibility to return/upgrade unit mid-project
Pros: Low upfront cost, flexibility, no ownership/depreciation.
Cons: Ongoing cost; long projects become expensive; no residual value.
Buy (~$15k–$75k upfront)
Best for:
- Permanent or long-term workspace (farm offices, permanent jobsite)
- Ownership/asset value matters (resellable in 5+ years)
- Customization (you build it once, own it)
- Plans to move the unit multiple times (mobile asset advantage)
Pros: Ownership, resellable, lower total cost over 5+ years, customizable.
Cons: Upfront capital, depreciation, maintenance/repairs on you.
Break-Even Math
Renting at ~$800/month costs $9,600/year. A turnkey 20ft office at $20,000 breaks even against rental at roughly 2–3 years. After that, ownership is pure asset. If you keep it 5+ years, buying is dramatically cheaper.
Rule of thumb: If your project or need lasts more than 2–3 years, buy. If it’s temporary, rent.
Cost Breakdown — Transparent Pricing
Turnkey (Ready to Deploy)
| Configuration | Price Range | Notes |
|---|---|---|
| 20ft Turnkey | $15,000–$35,000 | Basic to mid-finish; HVAC, power, windows included |
| 40ft Turnkey | $25,000–$75,000+ | Larger, more features; custom finishes run higher |

DIY (Buy Raw + Customize Yourself)
- Raw container starting point: Used 20ft ~$2,000–$3,800; New one-trip 20ft ~$3,500–$5,500
- Typical DIY buildout cost: $10,000–$50,000+ (labor + insulation + HVAC + electrical + finish)
- Total DIY cost: $13,000–$55,000 depending on finish quality and your labor
- Foundation/leveling: $500–$2,000 (gravel pad, blocks, or concrete)
DIY vs. Turnkey trade-off: DIY is cheaper if you supply labor; turnkey is faster and risk-free if you value your time and certainty.

Site Clearance & Access Requirements

- Driveway width: 10+ feet; if tight, notify us for placement options

Site Prep (Your Responsibility)

- Anchoring (optional but recommended in high-wind areas): Ground anchors or cable tie-downs (~$300–$1,000).
We’ll provide guidance on prep during your quote consultation.
Permits & ADA Compliance
Do I Need a Permit?
Yes — most jurisdictions require a permit for a semi-permanent structure. Zoning rules vary:
- Agricultural zones: Most permissive; farm offices often approved with minimal review.
- Commercial zones: Container offices are allowed but may require screening or specific setback distances.
- Residential zones: Many cities restrict containers; check your local zoning code before committing.
Action: Confirm with your local building department before purchasing. We can help you understand typical requirements for your area.
ADA Compliance
If your office is public-facing, employee-accessible, or client-facing, Title III ADA compliance applies. This means:
- Accessible entry/exit (ramp, if needed)
- Accessible interior layout (aisles, workstation height)
- Accessible bathroom (if included)
- Parking / drop-off access (if applicable)
Non-compliance penalties are significant ($55,000–$75,000+ first violation). If you’re unsure, consult an ADA specialist or your local disability services office. We can build ADA-compliant containers; just specify in your quote.

Frequently Asked Questions
Q: What’s the difference between a one-trip and used container?
A: One-trip containers are new or barely used (1–2 ocean voyages); they’re cleaner, more uniform, and longer-lasting. Used containers are older but fully functional and much cheaper (~40% less). Both work for an office; one-trip is premium, used is budget.
Q: Can I modify the layout (add/remove walls, change window placement)?
A: Yes — custom builds are our specialty. The more changes, the longer the timeline (10–12 weeks custom vs. 5–10 weeks standard). Discuss your layout in the quote.
Q: What if I want to move the office later?
A: Container offices are designed to be mobile. If anchored properly, it can be removed and relocated (with a tilt-bed truck). Budget $2,000–$5,000 for relocation logistics.
Q: Is a container office insulated well enough for winter / summer?
A: Yes — our units have full insulation (walls, roof, floor) and HVAC (heating & cooling). We size the A/C based on the container size and local climate. A 40ft High Cube with dual A/C stays comfortable year-round even in hot climates.
Q: Can I add a bathroom / kitchenette?
A: Yes — these are common add-ons. A basic bathroom adds ~$3,000–$8,000; a kitchenette $2,000–$5,000. Discuss in your quote.
Q: What happens if I want to sell it later?
A: Container offices are resellable assets. If you maintain it well, you can resell it in 3–5+ years for 50–70% of purchase price (depending on condition and local demand). It’s a depreciating asset but not a total loss like rent.
Q: Can I use a container office in a residential area?
A: Possibly, but check your local zoning first. Many residential zones restrict containers; some allow them as “accessory structures” (guest houses, studios). You may need a variance or conditional-use permit. We’ll advise during the quote.
Q: How long does a container office last?
A: A well-maintained container office lasts 25+ years. The steel frame is durable; HVAC and electrical need periodic maintenance (like any building).
