Portable
Porta cabins
A steel frame clad in insulated panels, delivered complete or built on site, and moved again later if needed. Common sizes follow container lengths of 20 and 40 feet.

Porta cabins and prefab buildings
Site offices, guard rooms, accommodation, clinics and classrooms that go up in days, not months: steel-framed and insulated, built to the size and layout you need.
Three ways to build it
Porta cabin, sandwich panel or light gauge steel
Modular
Sandwich-panel buildings
Insulated panels on a light steel frame, laid out to any plan and joined into rows or blocks. Quick to build and well insulated for heat and cold.
Permanent
Light gauge steel (LGS)
Cold-formed steel framing with board linings, which looks and works like a conventional building. Used for schools, clinics and two-storey blocks.
What people use them for
Typical buildings
Construction sites
Site offices and stores
Offices, meeting rooms, stores and guard rooms for the length of a project.
Workforce
Labour camps and accommodation
Dormitories, washrooms, kitchens and dining halls for site teams and remote operations.
Security
Guard rooms and check posts
Small insulated cabins at gates, barriers and perimeters.
Health
Clinics and pharmacies
Clinical and dispensing rooms inside working hospital grounds, such as our LGS pharmacy at PNS Shifa.
Education
Classrooms and schools
Extra classrooms, or complete school blocks, like our LGS schools in interior Sindh.
Remote sites
Mountain and coastal units
Insulated units for difficult sites, such as our sandwich-panel buildings at Balakot.

Price
What sets the price of a cabin
We quote every job, because two cabins of the same size can cost very different amounts. The main factors are:
- Size and layout. Floor area, ceiling height, and the number of rooms and partitions.
- Panels. The core material and its thickness. Thicker, better-insulated panels cost more but keep the inside cooler and cut air-conditioning bills. Our sandwich panel guide explains the choices.
- Fit-out. Electrical wiring, lights and sockets, air conditioning, toilets and plumbing, kitchen units and floor finishes.
- Quantity. Repeat units of the same design cost less each.
- Site and transport. Distance, access, and whether the base is a concrete slab, plinth or raised steel frame.
Send us the size, the use and the site and we will price it.
Questions
Porta cabin FAQ
01 · FAQ
What is the difference between a porta cabin and a container office?
A container office is a converted shipping container. A porta cabin is purpose-built with a steel frame and insulated panels, so it is usually lighter, better insulated and can be made to any size rather than the fixed container sizes.
02 · FAQ
How long does a prefab building take?
A standard cabin can be ready in days once the design is agreed. Larger sandwich-panel or LGS buildings take weeks rather than the months a concrete building needs. We give a programme with every quote.
03 · FAQ
Are prefab buildings hot in summer?
Not if the panels are insulated and thick enough. Insulated sandwich panels keep heat out far better than bare steel sheet, and the right thickness depends on whether the room will be air-conditioned.
04 · FAQ
Can a prefab building be two storeys?
Yes. Light gauge steel works well for two-storey buildings, such as our block in Sanghar.
