Good to know
- GST on fit-out works is 18%, and input credit is generally blocked because the work becomes part of the building; movable furniture and IT usually qualify. Confirm with your CA.
- Ask the landlord for a rent-free fit-out period: it usually covers approvals and part of the build.

How we work this out
Rules, not AI: your inputs times rates per city, gathered in November 2026 from builders, cement and paint brands, banks, interiors firms and government pages. Most published rates come from firms that sell this work, and they often disagree, so we show a range. Use it to plan and to compare quotes, not as a quote.
