An indicative prefab site office in Delhi NCR is about ₹1,700–₹2,600 per sq ft delivered and erected. A 20 × 10 ft office (200 sq ft) therefore plans at roughly ₹3.4–₹5.2 lakh. Panel thickness, MS structure, floor, electrical scope, transport, access and finish can move the final number.
On a live project, the site office controls drawings, measurements, billing, meetings and daily decisions. The mistake is buying a "cabin" before deciding how the team will use it. This guide gives you a practical BOQ, Delhi NCR planning cost and a clear way to compare basic and insulated options.
What should a prefab site office include?
A practical prefab site office should cover the management workflow first: a secure enclosed room, workstations, meeting space, electrical points, lighting, ventilation or air-conditioning provisions, data points, storage and a usable entrance.
On a live EPC site, the office is not just a cabin. It becomes the place where drawings, measurements, RA bills, safety records and subcontractor discussions happen. Design it around the people who will use it every day.
Kab kya use karein: use a single larger room when the team changes frequently; split project management, engineering and meeting functions when the project has a larger permanent staff.
| Item | Practical specification | Why it matters |
|---|---|---|
| Structure | MS box-pipe frame with properly fixed wall and roof panels | Controls rigidity and reduces site fabrication. |
| Walls/roof | PUF sandwich panels where thermal comfort is important | Reduces heat transfer compared with a bare sheet enclosure. |
| Floor | 18 mm board/ply or cement-board system over a suitable subfloor | Provides a usable office finish rather than a temporary shed floor. |
| Electrical | LED lighting, adequate sockets, DB/MCB, AC points and data provision | Prevents extension-cable clutter and later rewiring. |
| Openings | Powder-coated/aluminium windows and solid external door | Improves daylight, security and ventilation. |
How much does a prefab site office cost in Delhi NCR?
An indicative delivered-and-erected range for a basic insulated prefab site office in Delhi NCR is roughly ₹1,700–₹2,600 per sq ft, depending on structure, panel, floor, electrical and finish scope.
For a 20 × 10 ft office, the 200 sq ft area gives an indicative project value of about ₹3.4–₹5.2 lakh delivered and erected within NCR. This is an industry-range planning figure, not a Prefabshala quotation.
The number moves most when you change panel thickness, MS section, flooring, electrical scope, AC provision, quantity, transport distance, site access and finish level. A low-looking square-foot rate can become expensive if those exclusions are added later.
| Office type | Indicative range | 200 sq ft planning total |
|---|---|---|
| Basic site office | ₹1,700–₹2,000/sq ft | ₹3.4–₹4.0 lakh |
| Insulated PUF office | ₹2,000–₹2,350/sq ft | ₹4.0–₹4.7 lakh |
| Higher-finish management office | ₹2,300–₹2,600/sq ft | ₹4.6–₹5.2 lakh |
Site office checklist: what procurement should specify
Your BOQ should specify measurable items instead of saying only "portable cabin", because the same label can hide very different construction and finish levels.
- Dimensions — state external and usable internal dimensions; a 20 × 10 ft footprint gives 200 sq ft before wall and partition deductions.
- Wall and roof panels — specify panel type and thickness, skin material and jointing method; do not leave insulation as a verbal promise.
- MS structure — specify section sizes, spacing and protective coating system where required by the design.
- Floor — specify board type, thickness, finished flooring and whether skirting is included.
- Doors/windows — state quantity, approximate size, frame material, glass and locking arrangement.
- Electrical — specify DB, MCB/RCCB as applicable, number of lights, fans, sockets, AC points and earthing interface.
- Transport and erection — state whether loading, unloading, crane/forklift, installation and removal are included.
- Site interface — identify foundation/plinth responsibility, level tolerance, drainage and access for unloading.
PUF panel or ordinary sheet cabin: kab kya use karein?
Choose insulated PUF panels when the office will be occupied for long working hours, especially in Delhi NCR summers; a basic sheet enclosure is more suitable when the priority is very low initial cost and short occupancy. See the PUF panel thickness guide for 40/50/80 mm choices.
| Factor | Basic sheet enclosure | PUF-panel office |
|---|---|---|
| Heat control | Weak unless additional insulation is added | Better thermal resistance through insulated core |
| Daytime comfort | Often needs more active cooling | More stable indoor conditions when correctly detailed |
| Initial cost | Lower | Higher |
| Long occupancy | Less attractive | Usually more sensible |
| Best use | Short-duration, low-cost site shed | PM office, engineer office, longer project camp |
Why does site access matter more than the catalogue?
A prefab office can be simple to manufacture but difficult to install if the site has a narrow approach, overhead lines, soft ground or no unloading space.
Before ordering, record the road width, turning radius, gate size, overhead obstructions, unloading point and distance from unloading point to final position. In dense Delhi locations such as Model Town or Vasant Vihar, the access route can be more important than the cabin drawing.
On a busy site, plan the office position so it does not block material movement, fire access or future excavation. The cheapest cabin is not cheap if shifting it later requires dismantling other site facilities.
When is a prefab site office not the right answer?
Prefab is not automatically the best choice for every office: a permanent headquarters, a high-rise commercial office with complex services, or a site with no legal space for temporary occupation may require a different solution.
Prefab makes strongest sense when you need predictable construction, controlled factory fabrication and a structure that can potentially be dismantled or relocated. For a six-month project with an accessible site, it can also avoid weeks of wet civil work.
One practical detail: the panel joint above a door is a common place for water ingress if flashing, sealant and joint detailing are poor. The panel itself is not the whole waterproofing system.
Closing takeaway
If you are planning a site office, start with the people count, room functions and site-access drawing, then compare BOQs line by line. Also compare it against a container — see prefab site office vs container office.
