Converted ISO Shipping Containers
Shipping Container Offices
Modern Workspaces Built from ISO Cargo Containers
Turn a genuine cargo container into a workspace with real character. Porta Cabin Systems converts new and used ISO shipping containers into fully finished, ready-to-work offices — insulated against the Indian heat, wired for power and air conditioning, and fitted with doors, windows, flooring, and interiors of your choice. Because a shipping container office starts life as a marine-grade corten steel box built to cross oceans, it is exceptionally strong, secure, stackable, and ready to be moved wherever your work takes you.
Whether you need a rugged project office at a remote site, a striking sales lounge, a startup workspace, or a container cafe-cum-office, we handle everything under one roof: container sourcing, structural conversion, insulation, interiors, and pan-India delivery.

The basics
What Is a Shipping Container Office?
A genuine ISO cargo container, professionally converted into a complete, ready-to-work office.
A shipping container office is a standard ISO cargo container — the same steel boxes used on ships, trains, and trucks worldwide — professionally converted into an office. The conversion involves cutting openings for doors and windows, reinforcing the structure, insulating the walls and roof, and building out a complete interior with flooring, paneling, electricals, and climate control.
The result is a workspace with capabilities a conventional cabin can't match: marine-grade corten steel that shrugs off corrosion, ISO corner castings that let units be craned, stacked, and transported on any standard container trailer, and a bold industrial look that makes your office stand out.

Our Shipping Container Office Options
Every conversion starts with a genuine ISO container and ends with a workspace built around your team.
Compact all-rounder20ft x 8ft x 8.5ft
20ft Shipping Container Office
The compact all-rounder. A converted 20ft shipping container gives you about 150 sq ft of secure workspace — ideal for a site engineer's office, security and command room, kiosk, or a smart one-cabin startup office. Fits almost anywhere a car can park.
Open-plan space40ft x 8ft x 8.5ft
40ft Shipping Container Office
Around 300 sq ft of open-plan or partitioned space. Configure it as a project office with cabins and a meeting room, a training room, or a marketing suite with a glass front. An attached toilet and pantry fit comfortably within the footprint.
Extra headroom40ft x 8ft x 9.5ft
40ft High Cube Container Office
The high cube variant adds an extra foot of height — giving you room for false ceilings, concealed AC ducting, and a noticeably more spacious feel. The preferred choice for premium offices, showrooms, and customer-facing spaces.

Stacked & Linked Configurations
Because shipping containers are engineered to stack, we can build double-storey offices, side-by-side linked halls, and full container office complexes with staircases, balconies, and decks — a complete building, delivered in modules.
Choose your grade
New (One-Trip) vs. Used Shipping Containers — Which Should You Choose?
One-trip / new containers
Have made a single cargo voyage and are in near-new condition — clean panels, minimal dents, longest remaining life. Best for customer-facing offices and long-term installations.
Used containers
Cargo-worthy used containers cost significantly less and are structurally sound after inspection and refurbishment. We shot-blast, treat, and repaint every used container before conversion. Best for site offices and budget projects.
We source both, inspect every unit before purchase, and will always tell you honestly which grade suits your budget and use-case.

Frequently Asked Questions (FAQ)
Answers to the questions we hear most often about shipping container offices.
A basic converted 20ft shipping container office starts around ₹2 lakh using a refurbished used container. Fully fitted 40ft and high cube units range from roughly ₹4 to ₹9.5 lakh depending on container grade, interiors, and add-ons. These figures are indicative sample ranges. Contact Porta Cabin Systems for an exact quote.
Used cargo-worthy containers cost much less and are perfectly sound after inspection and refurbishment — ideal for site offices. One-trip (near-new) containers look better and last longer, making them worth it for customer-facing or long-term installations. We supply both and advise honestly based on your use-case.
A bare container does — a converted one doesn't. We insulate walls and roof with 50 mm PUF/Rockwool, add ventilation and AC provision, and use reflective exterior coatings, keeping interiors comfortable even in peak Indian summer.
Shipping containers are made of corten (weathering) steel, which is highly corrosion-resistant. We additionally shot-blast, prime, and repaint every unit with marine-grade coatings. With periodic repainting, it is designed for long-term use with proper maintenance.
Yes — this is their superpower. ISO corner castings are engineered for stacking, so we can build double-storey offices and multi-container complexes with proper staircases and safety railings.
No civil foundation is required in most cases. A level surface with concrete blocks, a plinth, or a simple PCC bed at the corner points is sufficient. We guide you on site preparation before delivery.
A high cube container is one foot taller (9.5ft vs 8.5ft external height). That extra height allows a false ceiling with concealed wiring and AC ducting, and makes the space feel much larger — usually worth it for premium and customer-facing offices.
Typically 3–5 weeks from order confirmation, depending on container availability and the level of customization. Placement at your site takes just a few hours.
