Estimate your office fit-out
Rates are taken from commercial fit-outs Greenbox has billed and completed, held at October 2026 prices.
Our rates, and the published city benchmark
The three specification grades in the calculator are set from commercial fit-outs Greenbox has billed and completed, audited line by line and held at October 2026 prices: ₹1,100–₹1,650 per sq ft basic warm-shell, ₹1,920–₹2,880 mid-specification and ₹2,830–₹4,240 for a collaborative hybrid workplace, all excluding GST. The table below is a different thing — Cushman & Wakefield's published city benchmark for a fully collaborative workplace. We use it only for the city gradient in the calculator; the rupee figures in it are theirs, not ours, and they sit well above what we bill.
| City | Hybrid workplace ₹/sq ft — C&W benchmark, not a Greenbox rate | Factor used |
|---|---|---|
| Mumbai | ₹6,567 | ×1.09 |
| Delhi NCR | ₹6,207 | ×1.06 |
| Bengaluru | ₹6,027 | ×1.03 |
| Chennai / Hyderabad / Pune / Kolkata / Ahmedabad | ₹5,847 | ×1.00 |
This calculator uses the same rate bands our estimators apply, derived from Greenbox project records and cross-checked against published 2026 market data. It is an indicative estimate, not a quotation — a real price depends on your actual drawings, site condition and material selection.
Design and build under one accountable roof
Bare shell versus warm shell
The single biggest variable after area. A bare shell requires you to build HVAC, washrooms, flooring base and ceilings — we add ₹900 per sq ft as a mid-point of the ₹600–₹1,200 range. Confirm in writing which you are leasing before budgeting anything.

Frequently asked questions
How much does an office fit-out cost per sq ft?+
Greenbox builds a basic warm-shell office at ₹1,100–₹1,650 per sq ft, mid-specification at ₹1,920–₹2,880 and a collaborative hybrid workplace at ₹2,830–₹4,240, excluding GST. Cushman & Wakefield's 2026 guide is a separate published benchmark for that one configuration and puts Mumbai at ₹6,567 per sq ft; it is not our rate. Bare shell adds ₹600–₹1,200 per sq ft.
What is included in the fit-out cost?+
Civil and partitions, MEP services (HVAC distribution, electrical, fire, data), joinery and furniture, finishes, AV and IT, plus contingency. It excludes landlord deposits, statutory approvals, and GST.
Why is MEP the biggest line?+
Because HVAC distribution, electrical distribution, fire detection and sprinkler modification, and structured cabling all have to be built new for your layout, largely above the ceiling where nobody sees them. At 25–32% of cost it is also the easiest line to under-quote.
Does this include furniture?+
Yes, workstations and built-in joinery are included at roughly 24% of the estimate. Loose and specialist furniture — designer chairs, breakout seating, soft seating — can add meaningfully and should be budgeted separately if you have specific brands in mind.
