Services before partitions
HVAC routing, sprinkler drops, smoke detectors, data and power layouts are resolved before a single partition goes up. All of these are expensive to move once the ceiling closes.

Chennai office fit-outs, delivered to a date.
An office fit-out is judged on one thing: whether people could work in it on the day you said they could. AlcorOne has delivered offices in Chennai — KG360 and a 600 sqft premium fit-out at Vridhi, Siruseri, completed in five weeks — and the discipline behind that is services coordination, not joinery.
What an office fit-out has to get right.
In a Chennai commercial building the constraints are rarely design ones. They are the landlord's fit-out rules, the services in the ceiling, and a lease date that has already been signed.
Building fit-out compliance
Commercial buildings and IT parks issue tenant fit-out rules covering permitted materials, ceiling access, working hours and service-lift booking. We read them before designing rather than after an approval is refused.
Cabins and glass partitions
Frameless glass cabin partitions need accurate openings and correct sequencing with the ceiling grid. Delivered at Vridhi Siruseri alongside quartz-topped workstations and fluted panelling.
Workstations that take use
Desks, overhead storage and cable management specified for daily use, with sealed machine-banded edges and surfaces that can be repaired in place rather than replaced.
Acoustics and light
Meeting rooms and cabins need acoustic separation that actually performs, and lighting levels appropriate to screen work rather than to a photograph.
Programmed to a handover date
We work backwards from your occupation date, with landlord inspections and services sign-offs marked on the programme as the dependencies they are.

Office fit-out cost in Chennai.
AlcorOne publishes its office rate instead of quoting it only on request: ₹3,000–10,000 per sq ft of carpet area, exclusive of GST. The four grades below apply in every city we execute in — Chennai differences sit inside the band rather than shifting it, and which grade a floor plate falls into is decided by specification and programme, not by headcount.
| Fit-out grade | Typical specification | Rate (₹/sq ft carpet) | Programme |
|---|---|---|---|
| Lean — startup & back-office | Open-plan led with a handful of cabins, laminate joinery, grid ceiling over most of the plate, catalogue LED lighting, ductable or split air conditioning, entry-grade workstations | ₹3,000–4,200 | 6–9 weeks |
| Standard corporate — most commercial floors | Cabin and open-plan mix, single-glazed partitions, full gypsum and grid ceiling, vinyl or laminate flooring, VRF or ductable HVAC, branded workstations, meeting-room AV provisions | ₹4,200–6,000 | 8–12 weeks |
| Premium — head office & client-facing | Reception in stone and veneer, acoustically treated meeting rooms, double-glazed partitions, specified lighting, VRF with BMS interface, branded ergonomic workstations and task chairs | ₹6,000–8,000 | 12–16 weeks |
| Boardroom grade — experience-led floors | Bespoke joinery and feature ceilings, acoustic pods, integrated AV throughout, imported furniture, full services integration and commissioning | ₹8,000–10,000 | 14–20 weeks |
Basis: AlcorOne execution rates as of , exclusive of GST. Indicative range for planning; the binding figure comes from an itemised BOQ against the actual site measurements and specification.
The band is all-in on the four heads that make up an office fit-out: partitions, ceilings, flooring and joinery; electrical, lighting, fire and data; HVAC; and loose furniture and workstations. Outside it sit GST, landlord deposits and fit-out charges, statutory NOC and fire clearance fees, anything in the landlord's base-building scope, IT active hardware and end-user devices, pantry appliances, and access control, CCTV or BMS integration — those are quoted as named lines rather than assumed inside the rate. This matters when comparing quotes, because a rate that leaves HVAC and furniture out is not a lower price, it is a smaller scope. The full inclusion and exclusion list, the specification ladder that moves a floor from ₹3,000 to ₹10,000, and the per-workstation arithmetic are published on our office fit-out cost page, linked below.

The corridor and the core are different jobs.
Chennai's office space sits in three bands, and the fit-out constraints follow the band rather than the brief. The same scope priced on OMR and priced in Nungambakkam runs to a different programme.
The IT corridor
OMR, Sholinganallur, Perungudi, Thoraipakkam and Siruseri hold the large floor plates in managed towers. Landlord and facility teams issue a fit-out manual, access passes and permitted working hours, and the submission sits ahead of every material on the programme.
The older CBD
Nungambakkam, T. Nagar, Alwarpet and Mount Road are smaller plates in buildings that were often not built as offices. Loading access is the usual constraint: what fits in the lift decides how joinery is broken down, which is a fabrication decision made before delivery rather than on the day.
Guindy, Ambattur and the industrial edge
Converted and industrial-adjacent stock varies widely in base-building services. Sprinkler layout, AC tie-in points and existing power capacity are confirmed at survey, because those three are where a converted floor most often departs from what the drawing assumed.
Questions we hear most.
How long does an office fit-out take in Chennai?
Five to ten weeks for a typical floor, depending on how much of the services scope is new. Our Vridhi Siruseri project — 600 sqft of premium fit-out with frameless glass cabin partitions, quartz-topped workstations and fluted panelling — was delivered in five weeks. A larger floor needing fresh HVAC routing and sprinkler modification sits at the longer end.
Have you actually delivered offices in Chennai?
Yes. KG360 and Vridhi Siruseri are both completed office projects in Chennai, and both have project pages with photography. We think that distinction is worth stating plainly, because a lot of interior firms present proposals and renders as delivery evidence.
Do you handle landlord and building approvals?
We prepare and submit the drawing set commercial buildings and IT parks require, and manage the comment cycle through to sign-off, along with contractor passes and worker documentation. The approval decision is the building's to make; the completeness of the submission is what determines how many cycles it takes.
Can you work while the office stays occupied?
Yes, in zones with hoarding, and out of hours for anything noisy, dusty or involving the ceiling void. Expect a longer programme than the same scope in a vacant floor. We will be direct about which parts of a scope can be phased around occupation and which genuinely need the floor cleared.
What does an office fit-out cost in Chennai?
Too dependent on services scope for a published rate to be useful. A floor with existing HVAC and ceiling in good order is a different order of cost from a bare shell needing new routing, sprinkler modification and full electrical distribution. We price from an itemised BOQ after a site survey, separating services, partitions, joinery and finishes.
Who manages the project day to day?
A site team reporting to our T. Nagar head office. On commercial work the value of same-city supervision is mostly about the landlord relationship — inspections, service-lift bookings and out-of-hours permissions all move faster when someone can attend in person.
How much does an office fit-out cost in Chennai?
₹3,000–10,000 per sq ft of carpet area, exclusive of GST — all-in, including electrical, lighting, fire and data, HVAC, and loose furniture and workstations. A lean open-plan floor lands at ₹3,000–4,200, a standard corporate floor at ₹4,200–6,000, a premium head office at ₹6,000–8,000, and boardroom-grade work at ₹8,000–10,000. The same band applies in every city we execute in; the binding figure comes from an itemised BOQ measured against your actual carpet area.
Are you office interior designers in Chennai, or interior contractors?
Both, under one contract. We work design-and-build rather than design-only, so the working drawings, the itemised BOQ and the material specification are ours, and so are the execution and the handover. Office interior designers in Chennai more often stop at the drawing set and pass it to a contractor they do not employ — and on a fit-out judged by a single occupancy date, that is where the date slips.
Send the floor plate and your occupation date.
Share the floor plan, the building's tenant fit-out rules if you have them, and the date your team needs to move in. We will come back with a services-first programme and an itemised BOQ.
