Office fit-out cost depends mainly on the condition of the space you take (bare shell or warm shell), the quality of finishes, how much mechanical and electrical work is needed, and your furniture and IT choices. A realistic plan budgets for design, civil and interior works, air conditioning, electrical and data cabling, furniture, IT, approvals and a contingency. Timelines run from design and approvals through to snagging, and the lease should give you time to finish before rent starts.
Key takeaways
- Know exactly what the landlord hands over; the gap between bare shell and warm shell changes the budget a lot.
- Air conditioning, electrical and data works are often the largest items after furniture.
- Negotiate a rent-free fit-out period and landlord approvals in the lease before you start design.
- GST input tax credit on fit-out works can be restricted, so involve your chartered accountant early.
Start with the handover condition
Coimbatore landlords describe handover in different ways, so get it in writing with photos.
| Handover type | Typically includes | What you still pay for |
|---|---|---|
| Bare shell | Structure, main walls, common areas, lifts, main power to the floor | Flooring, ceilings, partitions, washrooms (sometimes), HVAC, electricals, furniture |
| Warm shell | Bare shell plus flooring, washrooms, basic lighting, sometimes air conditioning | Partitions, cabins, workstation power and data, furniture, IT |
| Furnished or plug-and-play | Complete interiors and furniture | IT setup, branding, minor changes |
If you are still choosing space, factor fit-out into the comparison. A cheaper bare-shell rent can end up costing more once interiors are counted. Browse offices and workspaces in Coimbatore to compare handover types.
What drives the cost
- Design and project management: architect or design-and-build fees, drawings and site supervision.
- Civil and interior works: partitions, false ceilings, flooring, glass cabins, paint, doors, pantry and washroom upgrades.
- HVAC: the type of air conditioning system and its capacity, plus ducting and fresh air.
- Electrical: distribution boards, lighting, UPS and raw power points, earthing, and generator connection.
- Data and security: structured cabling, Wi-Fi, server or rack room, CCTV and access control.
- Fire safety: extinguishers, detection and any changes to sprinklers or alarms required by the building.
- Furniture: workstations, chairs, storage, meeting tables and reception.
- Branding and signage: lobby, wall graphics and external signs (which may need permissions).
- Contingency: hold a reserve for changes and surprises found on site.
Density matters too. A layout with many cabins and meeting rooms costs more than an open-plan floor of the same size. Ask your designer for two options and price both.
Typical stages and timeline
| Stage | What happens | Planning tips |
|---|---|---|
| 1. Brief and space planning | Headcount, departments, meeting needs, growth plan | Plan for your headcount a year or two ahead |
| 2. Design and costing | Layout, design intent, bill of quantities | Get comparable quotes on the same drawings |
| 3. Approvals | Landlord approval, building management rules, any local permissions | Start early; delays here push everything back |
| 4. Procurement | Ordering furniture, AC units, glass, lighting | Long-lead items should be ordered first |
| 5. Site works | Civil, ceilings, MEP, finishes | Agree working hours with the building |
| 6. Snagging and handover | Testing, defect list, cleaning, IT setup | Leave buffer before move-in day |
The total duration depends on size and complexity. Small, simple offices can be completed quickly; larger floors with custom HVAC and many cabins take considerably longer. Ask contractors for a programme with milestones and link payments to them.
Lease terms that protect your fit-out
- Rent-free period: ask for a fit-out period before rent starts, and define when it ends.
- Landlord approvals: consent to drawings should not be unreasonably withheld or delayed.
- Power load: confirm the sanctioned load available, and who pays for any enhancement from the power distribution utility.
- Ownership and removal: list what you can take away at exit.
- Restoration: agree the reinstatement standard now, so exit costs are predictable.
- Lock-in: a long fit-out investment argues for a lock-in on the landlord side too.

Approvals and compliance in Tamil Nadu
Interiors inside an approved building usually do not need a fresh building permit, but structural changes, new mezzanines or changes of use can. Check with the building management and, where needed, the local body. Keep fire exits, detectors and sprinkler coverage intact, and follow the building’s fire safety arrangements. If you will have ten or more workers, Tamil Nadu’s Shops and Establishments rules require registration and welfare facilities such as drinking water, washrooms and first aid, which your layout should provide for.
GST on fit-out spending
Most fit-out goods and services attract GST. Section 17(5) of the CGST Act blocks input tax credit on works contracts and goods or services used to construct immovable property on your own account, except plant and machinery. Items that stay movable, such as loose furniture and IT hardware, are generally treated differently. The line between the two has been litigated and amended, so ask your chartered accountant how to structure contracts and invoices.
Managed office as an alternative
If the upfront cost or time is a problem, a managed office puts the fit-out into a monthly fee. Our comparison of managed offices and conventional leases explains the trade-offs.
Frequently asked questions
What is the difference between bare shell and warm shell?
Bare shell is the basic structure with power to the floor. Warm shell usually adds flooring, washrooms, lighting and sometimes air conditioning, so the tenant’s fit-out cost is lower.
How long does an office fit-out take?
It depends on size, design complexity and approvals. Build in time for design, landlord approval, procurement of long-lead items, site works and snagging before your move-in date.
Can I claim GST on office interiors?
Credit on works that become part of immovable property is generally blocked under section 17(5) of the CGST Act, while movable items may qualify. Ask your chartered accountant.
Should I ask for a rent-free period?
Yes. For bare-shell or warm-shell space, a rent-free fit-out period is a common negotiating point. Define exactly when rent begins.
