Quick answer: Common porta cabin sizes in the UAE, what fits in each one (office, security cabin, accommodation, toilet) and how to choose the right dimensions.
“What is the standard size of a porta cabin?” is one of the first questions buyers ask. The honest answer is that porta cabins are built to order, so there’s no single standard. That said, most cabins in the UAE fall into a few common sizes, because they have to travel on a truck and be lifted by crane. This guide explains those sizes and what fits inside each.
What Limits Porta Cabin Size?
- Road transport: width and length have to suit a trailer and road rules. Very wide loads need special permits and escorts.
- Crane lifting: bigger cabins need bigger cranes.
- Site access: gates, roads and overhead lines on your site.
That’s why most single modules are around 2.4m to 3m wide and 3m to 12m long, with an internal height of about 2.4m to 2.7m. Larger buildings are made by joining modules.
Common Porta Cabin Sizes and Uses
Sizes below are typical and approximate. Every cabin can be built to your exact dimensions.
| Approx. size (L × W) | Typical use |
|---|---|
| 1.5m × 1.5m to 2.4m × 2.4m | Single-guard security booth, ticket booth |
| 3m × 2.4m | Security cabin with toilet, small office, single toilet unit |
| 6m × 2.4m to 6m × 3m | Site office for 2–4 people, store, 2–3 toilet block |
| 9m × 3m | Office with manager cabin and pantry, small accommodation room set |
| 12m × 3m | Office with meeting room and toilet, accommodation block, multi-cubicle toilets |
| Joined modules | Large project offices, dining halls, classrooms, camps |
How to Choose the Right Size
Count the People and Furniture
Allow space for desks, chairs, cabinets and movement around them. For accommodation, follow the authority’s minimum space per occupant. See our labour accommodation guide.
Add the Extras
A pantry, toilet, shower or meeting room each adds length. A security cabin with toilet needs more room than a plain booth.
Check Your Site
Measure the plot, gate width and crane position before finalising dimensions.
Think About the Future
Modular cabins can be extended later by adding modules, so start with what you need now.
Porta Cabin Size and Price
Size is one of the biggest cost drivers, along with panel type, fit-out and electrical scope. Read the porta cabin price guide for the full list.
Container Sizes for Comparison
If you’re considering a container office instead, sizes are fixed: a 20ft container is about 6m × 2.4m and a 40ft about 12m × 2.4m. Porta cabins give you more freedom on width and layout. Compare them in container office vs porta cabin.
