MK Portable Cabin builds site office cabins to your exact size, wires them, insulates them and delivers them ready to use — usually within days, not months. Over 10 years and 500+ clients across Mumbai, Navi Mumbai, Thane, Pune and the rest of India.
What is a site office cabin?
A site office cabin is a ready-made, movable office that is dropped onto your construction site so your engineers, supervisors and client representatives have a proper, weatherproof place to work from day one. It is built as a steel frame with pre-insulated PUF or EPS sandwich panel walls and roof, fitted with doors, windows, flooring, lighting and power points before it ever leaves our unit.
You prepare a level base; we deliver, place and level the cabin. The site office is running the same day.
Why contractors choose a cabin over a built room
- Speed. Fabrication runs while you prepare the plinth. Lead time is weeks, not months.
- Fixed, written price. One quotation for a defined specification — no open-ended site bill.
- It moves with you. When the project closes, the cabin goes to your next site. It stays an asset.
- No wet work. No bricks, no curing, no debris, no disruption to the main works.
- Resale value. A well-maintained cabin holds real second-hand value.
Standard sizes (and custom)
These are the sizes we build most often. Every one of them can be changed — we fabricate to order, so if your plot suits 11 ft × 22 ft, that is what we build.
| Size | Typical use | Comfortable for |
|---|---|---|
| 10 ft × 10 ft | Supervisor cabin, single-desk site office | 1–2 people |
| 10 ft × 20 ft | Standard site office with meeting corner | 3–4 people |
| 12 ft × 24 ft | Site office + separate PM cabin | 5–6 people |
| 20 ft × 20 ft | Main project office with drawing room | 8–10 people |
| 40 ft container type | Large project office, stackable units | 10–14 people |

What is inside as standard
- Frame — MS/GI steel sections, cut, welded and anti-rust treated before panelling
- Walls and roof — pre-insulated PUF or EPS sandwich panels, so the cabin stays workable through a Mumbai summer
- Flooring — plywood, cement board or chequered plate, on a supported sub-frame
- Doors and windows — lockable door, sliding windows with grills and mesh
- Electricals — light points, fan points, 5A and 15A plug points, MCB distribution box, AC point on request
- Finish — painted inside and out in your colour; your name and logo applied on request
Optional upgrades
- Air conditioning with a dedicated circuit and framed opening
- Attached toilet or a separate toilet cabin alongside
- Internal partition for a project manager’s cabin
- False ceiling, vinyl flooring and a glass front for client-facing sales offices
- Thicker panel where the cabin faces full sun all day
- Knock-down supply and on-site assembly where the approach road is narrow
What decides the price
We do not publish a single rate, because an honest price depends on what you actually need. These are the things that move it:
- Size — length, width and internal clear height
- Panel specification — PUF or EPS, and thickness in mm
- Frame section and gauge
- Flooring material
- Number of doors, windows and electrical points
- Finishing level — basic site office versus a client-facing sales office
- Delivery distance and unloading — whether a hydra or crane is needed
Tell us these on one phone call and you get a written quotation the same day, with every line spelled out so you can compare it honestly against anyone else’s.

Looking for a site office cabin supplier in Mumbai? Here is what to check first
Choosing a site office cabin supplier in Mumbai is less about the lowest quote and more about who actually fabricates, delivers and services the cabin. Many listings you will find are traders who forward your enquiry to a workshop and add a margin; when a panel leaks or a window jams in the second monsoon, there is nobody to send a fitter. We fabricate in our own Mumbra-Thane unit, so the team that cut your frame is the team that comes back to it.
Four questions separate a manufacturer from a middleman. Ask where the unit is fabricated and offer to see it. Ask what the wall panel actually is — PUF, EPS or plain CGI sheet — because the panel decides how hot the cabin gets by 3 pm and how long the paint lasts. Ask who arranges the hydra and trailer, and whether that cost is inside the quote or billed later. And ask what happens six months after delivery: a real supplier will name a service response time instead of changing the subject.
Also confirm the paperwork. A proper GST invoice with HSN, a written warranty on structure and panels, and a delivery note signed at your gate are what let your accounts team capitalise the cabin cleanly and what protect you if a claim comes up later.
We supply site office cabins across Mumbai, Thane, Navi Mumbai, Kalyan, Bhiwandi, Panvel and the MIDC belts, with over 500 happy clients so far. Share your size and site location and the quote reaches you the same day — +91 98676 48337 or WhatsApp.
Site Office Cabins: One Big Unit or Several Smaller Ones?
Most sites do not buy a single cabin — they buy site office cabins in a small set, because different people on site need different rooms. A typical mid-size project runs an engineer’s room, a contractor’s or client room, a small meeting space, a store for drawings and instruments, and a separate toilet unit. The question we get asked most is whether to take one long cabin and partition it, or several smaller cabins placed side by side.
Both work. The trade-off is mobility against cost per square foot:
| Approach | Works best when | Watch out for |
|---|---|---|
| One long cabin (30×10 or 40×10) with internal partitions | The site is stable for the whole project and you want the lowest cost per sq ft | Needs clear trailer access and crane room in one go; moving it later means moving everything |
| Two or three separate units (e.g. 20×10 + 10×10) | You want to shift part of the setup as work moves, or add rooms in phases | Slightly higher cost per sq ft; each unit needs its own levelling and power drop |
| A small cabin for office use only (8×8 or 10×10) | One or two people, a short job, or a satellite point on a large site | Fills up fast once a cupboard and a second table go in |
A practical rule from our own deliveries: allow roughly 40 to 50 sq ft per person who will actually sit there through the day, and keep the toilet as a separate unit rather than inside the office cabin unless the layout forces it — it keeps smell and plumbing away from the work area and makes both units easier to re-deploy on your next site.
If you are phasing a long project, buying a 20×10 now and adding a second unit later is usually cheaper than replacing one cabin with a bigger one in month eight. Tell us the headcount and how long the site runs, and we will lay out both options for you the same day.
Frequently asked questions
How long does a site office cabin take?
Depends on size and specification. A simple site office is quick; a fitted-out office with AC, partition and toilet takes longer. You get a firm target date when you place the order.
Can you build a size that is not in your list?
Yes. We fabricate to order. Give us the dimensions that suit your plot.
What base do I need to prepare?
A level, firm base — plinth blocks or a PCC pad, raised slightly above the surrounding ground with a fall for drainage. Send us a photo of the spot and we will tell you exactly what to prepare and what access we need.
Do you handle unloading?
Yes. Tell us the site conditions and we arrange the hydra or crane. If the approach is narrow, we can supply in knock-down form and assemble on site.
Is it hot inside?
Not if it is properly insulated. PUF or EPS sandwich panel walls and roof make a very large difference, and an AC point can be provided. This is the item people cut to save money and then regret — we will tell you honestly what your site needs.
Can I rent instead of buying?
For a short project, renting can work out better. For a project of a year or more, buying usually wins and you keep the asset. Tell us the project duration and we will give you both numbers.

How to Choose a Site Office Cabin Supplier in Mumbai
Picking the right site office cabin supplier in Mumbai decides whether your cabin lands on site in three days or three weeks, and whether it still looks presentable after two monsoons. Mumbai sites bring their own problems: narrow approach roads, society and MIDC gate permissions, salt-heavy air in the coastal belt, and inspection visits that happen with no notice. A supplier who fabricates locally and delivers daily around Thane, Navi Mumbai, Bhiwandi, Taloja and Panvel understands those problems; a trader forwarding your order to a far-off workshop does not.
Use this short checklist before you release a purchase order:
- Own fabrication unit — ask to see the workshop, not a catalogue. You should be able to inspect the frame and panel work before paint.
- Written specification — MS square-tube frame section, wall panel thickness, insulation type (PUF, rockwool or thermocol), flooring, roof slope and paint system should be on paper, not verbal.
- Transport and crane included — in Mumbai the hydra or crane charge and the road permit often cost more than people expect. Get it quoted upfront.
- Realistic delivery date — a standard site office cabin is a stock-and-fabricate item, not a six-week project.
- After-sales reach — a hinge, lock or leak problem should be fixed by someone who can reach your site the same week.
MK Portable Cabin fabricates at Mumbra, Thane and has delivered to 500+ happy clients across Mumbai, Navi Mumbai and Thane. Tell us your size, door and window count, and whether you need AC or a toilet attached — you will get a written quote the same day.

Choosing a Site Office Cabin Supplier in Mumbai: 7 Things to Verify Before You Pay
Picking a site office cabin supplier in Mumbai is mostly about avoiding the three usual problems – a cabin that leaks in the first monsoon, a delivery date that keeps moving, and a quotation that grows after the order. Here is the checklist our own customers use before releasing an advance to anybody, us included.
- Own workshop, not a middleman. Ask for the fabrication address and ask to see a unit under construction. A supplier who only forwards your order adds cost and cannot fix a problem later.
- Written specification sheet. Frame section size, wall panel thickness, insulation core (PUF, rockwool or thermocol), roof sheet gauge, flooring type. If these are not on paper, the quotation means nothing.
- Insulation named, not implied. “Insulated panel” is not a spec. PUF at 40 to 50 mm behaves very differently from 25 mm thermocol in a Mumbai May.
- Monsoon sealing detail. Ask how roof-to-wall joints and window frames are sealed, and whether the roof has a slope and drip edge. This is the single most common complaint about cheap cabins in the city.
- Delivery date in writing, with the crane question settled. A serious supplier asks for your gate width and site photos before quoting a date.
- GST invoice and warranty period. A proper invoice lets you claim input credit and gives you something to stand on if the unit fails early.
- Local references you can actually call. Ask for two sites in your own area and ring them.
We manufacture at our own Mumbra-Thane unit, supply across Mumbai, Thane, Navi Mumbai and the Taloja-Bhiwandi-Panvel MIDC belt, and have delivered to over 500 happy clients. Every quotation we send carries the full panel specification, the insulation type, the GST breakup and a committed delivery date – so you can hold the comparison next to anyone else’s.

Site Office Cabins: What to Check on Delivery Day Before You Sign the Challan
Most complaints about site office cabins are not manufacturing complaints — they are delivery-day complaints that nobody checked in the ten minutes before the challan was signed. Once the hydra leaves and your signature is on paper, a binding door or a dented panel becomes your argument to win rather than the supplier’s. Here is the short list our own supervisors run through with the customer before they hand over the keys.
Measure the inside, not the outside. Run a tape across the internal floor. A 20×10 unit should give you close to 20 feet clear inside, not 20 feet across the outer frame. If the order sheet promised internal size, the tape should prove it.
Open and close every door and window. Cabins travel on bad roads. A door that binds at the top or a sliding window that has jumped its track is a five-minute fix on delivery day and a half-day job a month later.
Switch on the power. Ask for a test on the site supply or a genset — every light, every fan point, every socket and the MCB. Check that the earthing wire is actually connected at the board and not just curled behind it.
Walk the roof line and the corners. Look along the outside of each wall for dents, panel joints that have opened, or sealant cracked in transit. Confirm the roof slopes away from the door side so monsoon water does not pool at your entrance.
Confirm the levelling and the plinth. The cabin should sit on firm, level bearing — plinth blocks, a concrete pad or ISMB sections — not directly on loose soil. An unlevel cabin racks its own frame within a few months, and then the doors stop closing on their own.
Match the challan line by line to the quote. Size, panel thickness, number of windows, flooring type, AC provision, colour. Tick each one. Anything that differs is far easier to settle while the vehicle is still on site.
When we deliver site office cabins in Mumbai, Navi Mumbai, Thane, Bhiwandi or Panvel, our team runs this exact check with your site engineer and only then takes the signature. If something is not right, we correct it or replace the unit. Call 98676 48337 or WhatsApp us with your size and we will send a written quote the same day.
