Office Interior Cost Per Sq Ft in Chennai
Updated October 2026. Officea's published rates for office interior fit-out in Chennai, by finish tier, GST extra. Many Chennai offices are warm-shell tech park floors along OMR and Mount–Poonamallee Road, where the budget goes mainly on extending the building's services; in older central buildings more of it goes on new air conditioning and power.

What drives fit-out cost in Chennai
The rate card applies across Chennai, but where a project lands within its tier depends on the building, the climate and the logistics. These are the points we check on a site visit.
Warm shell or bare floor
A warm-shell floor in an OMR or Mount–Poonamallee Road tech park usually comes with air-handling provisions, sprinklers and a power allocation, so the MEP budget goes on extending what is there. A bare floor in an older building in Nungambakkam, T. Nagar or along Anna Salai may need new air conditioning, a new panel or extra supply from the distribution company, which raises the MEP share.
Air conditioning sized for humidity
Removing moisture as well as heat can mean more fresh-air treatment, larger coils and more careful condensate drainage than a design that only looks at temperature. This sits inside the HVAC line of the budget and is worth getting right, because fixing a clammy office later costs more.
Materials for damp and salt air
Moisture-resistant boards, sealed joinery edges and powder-coated or stainless fixings cost slightly more than standard items. Near the coast, and for outdoor units, they belong in the specification from the start rather than as an extra.
Monsoon timing
A fit-out that runs through October to December needs covered storage, protection for delivered furniture and buffer time in the programme. These carry a modest cost, and an earlier start in the year can avoid most of it.
Building and SEZ charges
Tech parks often ask for a refundable fit-out deposit, contractor insurance and fees for after-hours lifts, security or power during the works, and SEZ campuses add gate-pass procedures. These are small next to the build cost but belong in the budget from day one.
Night work and floor size
Noisy work restricted to nights and weekends adds labour hours. Large floor plates spread fixed costs such as site set-up, supervision and design over more square feet, so smaller floors often land higher within a tier.

Common questions about fit-out cost in Chennai
What does office interior cost per square foot in Chennai?
Our published 2026 rate card for Chennai runs from ₹1,800 per sq ft for a Basic finish, through ₹2,200 for Medium and ₹2,600 for Good, to ₹4,500 for High end, GST extra. Where a project lands within a tier depends on the shell, the HVAC route and the scope agreed after a site visit.
Does Chennai's humidity add to the cost of a fit-out?
It changes where some of the money goes rather than adding a separate charge. Air conditioning has to remove moisture as well as heat, and wet areas need moisture-resistant boards and sealed edges. These choices are built into the HVAC and joinery lines of the quotation at each tier.
Does this rate include furniture?
The rate card covers civil, MEP and finishes. Furniture is typically quoted separately and commonly adds 20 to 30% to the total project cost of a Chennai office. Use the calculator on this page for a fuller estimate including furniture.
How accurate is a per-square-foot estimate for a Chennai office?
It is a sound starting point for a budget, not a final number. A warm-shell floor in an OMR tech park and a bare floor in an older central building can land at different points in the same tier. A firm quotation follows a site visit and a review of the landlord's fit-out manual.
Is GST included in these rates?
No. All rates on this page and in the calculator are before GST, which is charged at the applicable rate. If your Chennai office is an SEZ unit, tell us early, because the paperwork for deliveries into the zone can differ.
