Cost by Mumbai micro-market
Fit-out cost varies across the city — partly building grade, partly how strict the landlord is, partly labour access.
| Location | Typical fit-out ₹/sq ft | Building character | Programme impact |
|---|---|---|---|
| BKC | ₹2,560 – ₹3,840 | Grade-A towers, strict manuals, mandated vendors | +2–4 wks approvals |
| Lower Parel | ₹2,220 – ₹3,330 | Mill-land conversions and new towers | +2–3 wks |
| Andheri East / MIDC | ₹1,380 – ₹2,070 | IT and back-office stock, flexible landlords | Baseline |
| Powai | ₹1,620 – ₹2,430 | Corporate parks, good service access | Baseline |
| Thane / Navi Mumbai | ₹1,580 – ₹2,460 | Larger plates, easier logistics | −1–2 wks |
Excluding GST, warm shell assumed. Bare shell adds roughly ₹600–₹1,200/sq ft. Each band is ours and matches the suburb page it links to — taken from Mumbai commercial fit-outs Greenbox has billed and completed, audited line by line and held at October 2026 prices.
Rent makes efficiency worth real money
In BKC, every square foot you occupy carries a rent cost for the length of your lease. An office that needs 12,000 sq ft because it was planned badly, when 10,000 would have served, is not a one-time overspend — it is a recurring one for five years. This is why we run a test fit before a client signs, not after.
The cheapest square foot in Mumbai is the one you did not have to lease.

How we run a Mumbai office project
- Test fit before you signWe take the landlord's plan and prove how many people, cabins and rooms it truly holds. Free, and it has saved clients from the wrong lease more than once.
- Fit-out manual reviewWe read the building's rules, list mandated vendors and approvals, and price them in from the start.
- Design & landlord submissionDrawings go for approval in parallel with detailed design, not after it.
- Services firstHVAC, electrical, fire and data before any finish work — the sequence that prevents rework.
- Phased handoverZone by zone, each fully functional, so your team keeps working.
They flagged two landlord-mandated vendors during feasibility that our previous contractor had missed entirely. That alone saved us a mid-project surprise.
Test fit showed we needed 20% less space than we were about to lease. Paid for the whole design fee before we started.
Phased handover meant zero lost business days. Cabins, then workspace, then boardroom.

Frequently asked questions
How much does office interior design cost in Mumbai?+
₹1,220–₹1,840 per sq ft for a basic warm-shell fit-out, ₹2,130–₹3,190 for mid-specification and ₹3,140–₹4,700 high-specification, ex-GST. Cushman & Wakefield's 2026 Mumbai benchmark of ₹6,567 per sq ft is a separate published figure for a fully collaborative hybrid workplace — the highest of any Indian city, and not a Greenbox rate.
Which Mumbai areas do you work in?+
BKC, Lower Parel, Andheri East and West, Powai, Goregaon, Malad, Thane and Navi Mumbai. We are equally comfortable in Grade-A towers with strict fit-out manuals and in older, more flexible commercial stock.
Why is Mumbai more expensive than Bengaluru or Delhi?+
Higher skilled-labour rates, restricted material movement in high-rises, stricter Grade-A landlord requirements with mandated vendors, and limited working hours which push work into premium night shifts. The gap is roughly 8–9% against Bengaluru.
Do you offer a test fit before we sign a lease?+
Yes, free of charge. We take the landlord's floor plan and produce a realistic layout showing actual desk count, cabins, meeting rooms and circulation. It regularly changes which floor — or which building — a client chooses.
Can work happen at night in Mumbai office buildings?+
In most Grade-A buildings, yes, and often it is mandatory for noisy work. Night shifts carry a labour premium but can compress the programme significantly. We confirm the building's permitted hours during feasibility and build the schedule around them.
