The renovation rule of thumb
If you are not moving water, it is a refresh. The moment you move water, it is a renovation — and the timeline doubles.
Greenbox site principle
The trade rates above are taken off completed Greenbox renovations — measured, invoiced and reconciled, held at October 2026. Plumbing is the one line we carry as an allowance rather than an audited rate, because it is the one that changes most once the floor is open. Everything here is an indicative estimate, not a quotation.

Frequently asked questions
How much does home renovation cost in India?+
It depends how deep you go. A cosmetic refresh runs ₹380–₹650 per sq ft of carpet area, a partial renovation ₹1,350–₹2,200, a full renovation ₹2,330–₹3,490, and a gut and rebuild ₹3,730–₹5,600. In Mumbai each band sits about 25% higher. All figures exclude 18% GST.
Is renovation cheaper than a fresh interior?+
Often not. Renovation adds demolition, debris removal and the risk of discovering problems behind existing surfaces — old wiring, leaking pipes, uneven floors. A fresh fit-out in an empty flat is more predictable and frequently cheaper per sq ft.
How long does a renovation take?+
Four to six weeks for a cosmetic refresh, ten to sixteen weeks for a full renovation with flooring and plumbing changes. Add time if you are living in the property during the work, which typically extends the programme by 30–50%.
Do I need society permission to renovate?+
In Mumbai, almost always. Most societies require a written NOC, a refundable deposit, a worker list, and compliance with permitted working hours. Structural changes need additional approvals and should never be undertaken on a contractor's assurance alone.
