What is it?
Prefab Site Offices
Construction projects and industrial plants cannot wait months for a permanent office building to be erected — project teams need functional, professional office space from the first week on site. Poojary Prefab's prefab site offices are designed, manufactured, and dispatched from our Wagholi facility as complete factory-finished units. Structural framing, insulated wall and roof panels, internal partitions, electrical wiring, plumbing provisions, flooring, and finish are all completed before the unit leaves the factory gate.
Unlike standard porta cabin units, our prefab site offices are engineered structures — not modified shipping containers or site-assembled tents. They are built to customisable floor plans from 150 sqft single-room units to multi-room office complexes exceeding 5,000 sqft, with options for conference rooms, toilet blocks, pantry areas, server room provisions, and dedicated generator rooms. Insulated PUF sandwich panels maintain internal comfort across Maharashtra's extremes — from 45°C Vidarbha summers to Sahyadri highland winters.
Every unit is delivered with MEP services pre-installed: concealed electrical conduits, MCB distribution boards, earthing provisions, LED lighting, data cable raceways, and split AC provisions. Plumbing rough-in, hot and cold water supply, and IPS flooring with tile finish are standard across all our site office configurations. With a 21–45 day delivery timeline from order confirmation, you get a professional office environment on site without delaying your project mobilisation schedule.
Configurations
Which Type Do You Need?
Every site has different requirements. Here's how our range breaks down.
Single-Room Site Office
Compact 150–300 sqft single-room units for site engineers and supervisors. Desk space for 3–6 persons, AC provision, electrical DB, and toilet provision. Delivered as a single unit, ready to connect to site services.
Multi-Room Office Complex
2,000–5,000 sqft multi-room complexes with separate conference rooms, manager cabins, open-plan workstation areas, server rooms, and attached toilet blocks. For large EPC projects and plant head offices.
Project Management Office
Premium PMO configurations with glass partitions, raised flooring provisions, 24-way distribution boards, multiple AC zones, and full IT infrastructure provisions. For senior project teams and client-facing site offices.
Industrial Plant Office
Heavy-duty site offices for industrial plant locations — reinforced flooring for equipment movement, higher electrical loads, cable management provisions, and HVAC designed for dusty or corrosive environments.
Key Benefits
Stronger by Design. Smarter by Choice.
21–45 Day Project Mobilisation
Conventional site office construction takes 3–6 months. Our factory-finished prefab units are on site and connected to services within 21–45 days of order — so your project team is functional from the first month, not the third.
Insulated for Year-Round Comfort
100mm PUF sandwich panels provide a thermal resistance (R-value) equivalent to 200mm brick walls. Internal temperatures stay 8–12°C cooler than ambient in summer — reducing AC load and improving working conditions even before air conditioning is switched on.
MEP Included — No Site Coordination
All electrical wiring, lighting, data raceways, AC provisions, and plumbing rough-in are factory-installed and tested before dispatch. On site, you connect power and water at the designated entry points — no MEP sub-contractor coordination required.
Relocatable — Maximise Asset Value
Unlike a permanent RCC office, our prefab site offices dismantle and redeploy to your next project. Structural panels and framing are re-usable across multiple project cycles — reducing the cost per project and eliminating the write-off at project completion.

What Our Clients Say
Honestly didn't expect this level of finish on a PEB structure. The fabrication was clean, the erection crew knew what they were doing, and we were operational two weeks before our target date. Will definitely be coming back for our next shed.
We've used three different prefab vendors over the years. Poojary Prefab Pvt Ltd is the only one that gave us a fixed price and actually stuck to it. No surprises on the final invoice. That alone is worth everything.
The cold storage has been running at -22°C continuously for 18 months. Not a single structural complaint. Our FSSAI inspection went through without a hitch. Genuinely impressed.

We needed a 400-person labour camp set up before monsoon hit. Poojary Prefab Pvt Ltd's team worked through weekends to make it happen. The workers themselves said it was better than camps they'd seen on other sites.
I was sceptical about PEB for a pharma facility — clean room requirements are strict. Poojary Prefab Pvt Ltd walked us through every spec, made the necessary design changes without fuss, and delivered a building that cleared validation on the first pass.
What I appreciate most is that there's one number to call. No chasing multiple contractors. When a purlins alignment issue came up during erection, the site supervisor sorted it the same afternoon without escalating it into a big deal.

We've done three warehouses with Poojary Prefab Pvt Ltd across Maharashtra. Each one handed over on time, each one at the quoted price. That kind of consistency is rare in this industry.
The site office cabin they set up for us was ready in five days — AC, electrics, partitions, the works. We've had it for two years now and it still looks good. Build quality is solid.
I compared four vendors before going with Poojary Prefab Pvt Ltd. Their quote wasn't the cheapest but they were the only ones who could show me a completed project of similar scale nearby. That visit sold me.
