Built in the Factory, Not in a Field
“Prefabricated” is a word that gets used loosely. Some suppliers mean a kit of panels that a crew bolts together on your land over a week. When we say prefabricated, we mean the cabin arrives finished — walls, roof, floor, wiring, doors, windows, paint — and the only thing left to do on site is connect the power.
That difference matters. A cabin built under a factory roof is square, dry and inspected. A cabin assembled in a field in July is whatever the weather and the crew allowed that day. This page walks through exactly what happens between your enquiry and the crane setting the cabin down. If you are still deciding whether a prefab cabin is right for you at all, start with our prefab porta cabin buyer’s guide instead — this page assumes you have decided and want to know how it is made.
How Your Cabin Is Built
Step 1 — Drawing and confirmation
Day 0–2You tell us the size, what the cabin is for and where it is going. We send back a dimensioned drawing showing the door, windows, partitions and electrical points. Nothing is cut until you approve it.
Step 2 — Frame fabrication
Day 2–6The base and wall frames are welded from MS C-channel (75 × 40 mm) or RHS (50 × 50 × 3 mm) on a flat jig, so the cabin is square and the floor is level. Galvanised C and Z purlins go in for the roof. Lifting lugs are welded to the corners now, not bolted on later.
Step 3 — Skinning and insulation
Day 6–101.5–2 mm MS sheet — or GI / PPGI if you have chosen it — is fixed to the frame. 30–50 mm glass wool or rock wool goes into the wall and roof cavities, then the inner lining closes it up. The sloping roof gets EPDM waterproofing at every joint.
Step 4 — Floor, doors and windows
Day 10–1318 mm cement board is laid on the floor joists and finished with 2 mm vinyl. The MS flush door and aluminium sliding windows are fitted and adjusted so they close properly — something that is surprisingly hard to get right on site.
Step 5 — Electricals and finishing
Day 13–17Concealed wiring, MCB board, LED lights, fans and modular switches are installed and tested. The whole cabin is primed with epoxy zinc phosphate and finished in PU topcoat in your colour.
Step 6 — Inspection and dispatch
Day 17–21Every cabin is hosed down to check for leaks, every circuit is tested, every door and window is opened and closed. Then it is loaded on a trailer and driven to your site, where a crane or hydra places it in one lift.
Smaller standard cabins move through this faster; large or heavily customised ones take the full three weeks.

What It Costs
This cabin is sold at the single price shown at the top of the page, inclusive of 18% GST, complete with floor, door, windows and full electrical fit-out. Transport and crane charges are calculated from your delivery pincode and shown before you pay, so there is nothing to settle when the truck arrives.
Set against building the same room in brick and RCC, you are trading a construction programme for a delivery date — and you keep an asset you can lift and reuse at the next project rather than demolish.
Standard sizes can be ordered online with UPI, cards or net banking. Custom builds are quoted within one working day.
Who Buys Prefabricated Cabins From Us
Prefabricated vs Built on Site
| Prefabricated | Brick & RCC on site | |
|---|---|---|
| Time | 7–21 days in the factory, one day on site | Two to four months, weather permitting |
| Quality | Jig-welded frame, factory-tested wiring, leak-checked before dispatch | Depends on the crew, the weather and who is watching |
| Disruption | No material dumps, no masons, no curing time on your land | All of the above, on your site |
| Reuse | Lift it, move it, use it again | Demolish it |
| Cost | Fixed quote agreed before fabrication starts | Estimates, extras and delays |
Where brick still wins is a permanent building that will never move and has to match the rest of a permanent campus. If that is the requirement, our building construction contractor page is the right one. For everything else, prefabricated is the practical choice.
Preparing Your Site
You need a level base — compacted ground, a PCC bed or concrete blocks at the corners — and access for a trailer and crane. That is all. Once the cabin is placed, connect the power supply and it is ready. Water and drainage are only needed if you have chosen an attached toilet or pantry.
We deliver anywhere in India from our Tamil Nadu factory at Kamandoddi, near Hosur.
