Office Interior Design and Build
in Kolkata

IBS designs and builds office interiors in Kolkata through its local teams in the city. An in-house design team draws the interior, the MEP (mechanical, electrical and plumbing), the HVAC (heating, ventilation and air conditioning) and the fire fighting. IBS’s own engineers and workmen build it, or build your architect’s design. Kolkata adds three questions: which body sanctions building work at the address, when the partition notice goes in, and at what hour a lorry may deliver.

Who designs and builds office interiors in Kolkata, and which authority covers the floor?

IBS is among the office interior designers in Kolkata that build what they draw, through local teams in the city. The rules depend on the address. The Kolkata Municipal Corporation sanctions building work in the central business district, the Nabadiganta Industrial Township Authority in Salt Lake Sector V, and the New Town Kolkata Development Authority in New Town. Fire time limits and the Bengali signage order follow the Corporation’s boundary.

What is a high-risk building?

A high-risk building is the class West Bengal’s fire Act places its duties on: a high-rise building, or a building of an occupancy the State has notified. A high-rise is 15.5 metres or more inside the Kolkata Municipal Corporation’s area and above 14.5 metres in the rest of the State.

What is extension of load?

Extension of load is the term West Bengal’s electricity regulations use when an existing consumer takes more load on a connection. A fit-out needs it when new HVAC plant such as VRF (variable refrigerant flow) outdoor units, a server room or a pantry draws more than the connection allows.

Address

Which authority covers an office in Kolkata: the Corporation, Nabadiganta or New Town?

Three bodies sanction building work across Kolkata’s office districts, and three other rules follow the same line.

Central business district

  • The Kolkata Municipal Corporation (KMC). Its Act of 1980 requires the Municipal Commissioner’s previous sanction for the building work it lists
  • Cushman & Wakefield draws this district around Park Street, Camac Street, AJC Bose Road and Theatre Road

Salt Lake Sector V

  • The Nabadiganta Industrial Township Authority, whose website says it is responsible for the sanction of building plans
  • We read neither the law that created it nor any building rules of its own

New Town

  • The New Town Kolkata Development Authority. Its Act of 2007 bars building work without its previous sanction
  • Cushman & Wakefield’s market report has a Rajarhat row and none for New Town. We read no boundary map, so ask the landlord which body sanctioned the building

What follows the line

  • Fire applications: 15 days in KMC areas, 30 days in the rest of West Bengal
  • High-rise height: 15.5 metres inside the Corporation’s area, above 14.5 metres outside
  • Bengali at the top of signboards: a Corporation order, with nothing comparable found for the other two
  • That Sector V and New Town lie outside the KMC area is our reading. No document we read says so in terms

Partitions

Does an office interior need a building permit in Kolkata?

Inside the Corporation’s limits, the Building Rules of 2009 list work that needs no building permit. Partitions are on it, with a notice period.

No permit required

  • An internal partition wall “which does not violate any of the provisions of the Act or these rules”, such as the gypsum drywall around cabins
  • A false ceiling “for air-conditioning, lighting or decorative purposes”: the gypsum or grid ceiling that carries diffusers, sprinkler heads and smoke detectors
  • Whitewashing, painting, and reflooring an existing floor with new screed, carpet or vitrified tile

Fifteen days’ written notice

  • Partition work may not start until the Municipal Commissioner has had fifteen days’ notice in writing, stating the nature of the work
  • The false ceiling, the painting and the reflooring carry no notice period
  • Send the notice the day the partition layout is frozen. It is yours to give. IBS can prepare the drawings and do the liaison, charged for separately

The catch in the Act

  • The Corporation’s Act counts it as erecting a building to convert a building built as offices, by subdivision or addition, into a greater or lesser number of offices. That needs the Municipal Commissioner’s sanction
  • We could not establish how the Corporation squares this with the no-permit rule. If your layout turns one office into several, ask it in writing before the notice goes in

Sector V and New Town

  • The 2009 rules are the Corporation’s. We read no equivalent list for the other two bodies
  • New Town’s Act carries the same subdivision wording and the same open question. Ask the authority in writing what it requires for interior work

Fire law

Who is responsible for fire safety in a leased Kolkata office, and what is the certificate?

The West Bengal Fire Services Act, 1950 splits the duty for a high-risk building between owner and occupier. The latest amending Act we found is of 2022.

Owner and occupier

  • The owner provides the fire prevention and fire safety measures. The occupier does so only where the owner is not traceable
  • The occupier, which includes a tenant liable to pay rent, maintains them “in good repair and in efficient condition at all times”
  • On a fitted floor those are the sprinkler heads, smoke detectors, call points, the hose reel, the hydrant landing valve and the wiring to the fire alarm panel

The certificate

  • A Fire Safety Recommendation comes first, then the Fire Safety Certificate, the paper a landlord may call the fire NOC (no objection certificate). It is obtained from the Director-General of the fire service or the nominated authority
  • A 2018 amending Act gives it three years from the date of issue. We did not find the notification that starts that Act, and a department order of 9 December 2025 calls the term “usually 3 (three) years”

Height, size and time

  • Since March 2024 offices up to 15.5 metres in height and up to 500 sq m in total floor area fall outside the high-risk class and upload a yearly self certification instead. The notification speaks of “buildings or part of a building”, and we could not establish how the height limit is read for a small floor in a taller tower. Ask the fire service
  • The fire service’s time limit is 15 days for KMC areas and 30 days elsewhere in the State, for a Recommendation, a Revised Recommendation or a Certificate

On your floor

  • No person may tamper with, alter or remove fire safety equipment in a high-risk building. Get the landlord’s written agreement before a layout moves sprinkler heads, smoke detectors or call points
  • We could not establish whether a fit-out needs a Revised Recommendation. Ask the landlord and the fire service
  • Occupiers hold a mock fire drill every year. The fire rules of 2003 were not read

IBS in Kolkata

What should you check before appointing office interior designers in Kolkata?

Ask each of the commercial interior designers in Kolkata on your shortlist four things. IBS’s answers follow.

Who is on the floor

  • IBS is a national contractor with a local presence in Kolkata, and its local teams deliver its projects in the city
  • The trades are IBS’s own engineers and workmen: civil work, MEP, HVAC, fire fighting, painting and furniture
  • Progress is reported to the PMC (project management consultant) against the programme, with HSE (health, safety and environment) and quality plans
  • At handover come test certificates, as-built drawings and a closed snag list, with the defect liability period your contract sets

Who draws

  • An in-house design team covers interiors, MEP, HVAC and fire fighting. With no architect, it designs the office and IBS builds it
  • On an architect-led project IBS builds from the architect’s GFC drawings (good for construction) and does not compete for the design
  • Shop drawings come before fabrication, and a mock-up is built where the contract asks for one

How the price is built

  • A site survey of the floor, then a line-item BOQ (bill of quantities). IBS quotes no rate per square foot
  • Materials are options priced against your budget, and you choose: plywood, MDF (medium-density fibreboard) or HDHMR (a denser, moisture-resistant board), laminate or veneer, carpet or vitrified tile
  • The quotation shows the lead time of long-lead equipment against the programme
  • Permits, licences and NOCs are the client’s to obtain. Liaison and application drawings are a separate, charged service

Whose lists it is on

  • Approved vendor at Adani Airports, HDFC ERGO, Reliance Retail, Godrej Finance, EPSON, Duravit, HSBC, Tata CLiQ, Canon, Aditya Birla Fashion and Retail and HDFC Life
  • Enterprise clients include Adani Airports, Reliance Retail, Tata CLiQ, Aditya Birla Fashion and Retail, GroupM, Belgian Waffle, EPSON, Canon, Planet Retail, Society Tea and Duravit
  • Largest single order executed: ₹25 Crore
  • BCAS (Bureau of Civil Aviation Security) clearance for the entire airport premises, airside included, and all registrations required under Indian law

Calendar

When can goods vehicles deliver in Kolkata, and what do Durga Puja and the monsoon change?

Every day

  • Heavy and medium goods vehicles are restricted from 06.00 to 22.00 hours on all days throughout the city, except in the port area
  • Light goods vehicles may move from 12.00 to 16.00 and from 22.00 to 06.00
  • So a lorry of gypsum board, plywood, MDF, vitrified tile, glass, DB panels (distribution boards) or VRF outdoor units arrives at night. Confirm the loading bay and service lift are open then
  • The notification, of 18 December 2024, is Kolkata Police’s. We read no order for the police area covering Sector V and New Town

Durga Puja, as ordered for 2026

  • The notification of 30 September 2026 prohibits all goods vehicles within the city in daily blocks on the Puja days, the first from 6 am on 13 October to midnight and the last ending at 4 am on 20 October
  • From 13 to 19 October light goods vehicles have an added window from 12 pm to 3 pm, and goods vehicles of up to 1,600 kg gross weight are allowed up to 3 pm. Immersion-day blocks follow, the last ending at 5 am on 25 October
  • Durga Puja moves each year, so look for that year’s notification

Holiday lists

  • The Finance Department’s 2026 holiday list puts Maha Astami, Maha Nabami and Dasami on 19, 20 and 21 October
  • The police notification puts Astami on 18 October and Navami on 19 October, a day earlier. We did not resolve the difference
  • Holiday lists bind banks and government offices. They do not close a private site

Monsoon

  • IMD (the India Meteorological Department) gives Kolkata a normal onset of 11 June and a normal withdrawal of 12 October, in a 2020 press release we read in an archived copy. Its longer research report has no Kolkata row
  • The items to date are outdoors: VRF outdoor units, refrigerant pipework, cable conduit and roof penetrations for ducting. In 2026 the first Puja block falls on the day after the normal withdrawal date

Power

Who supplies electricity to a Kolkata office, and how long does extra load take?

WBERC (the West Bengal Electricity Regulatory Commission) set time limits for extension of load in 2010. Four amendments, the last in 2020, leave those limits unchanged.

The licensee

  • CESC Limited is, in the regulator’s words, a distribution licensee “for supply of electricity in Kolkata metro and some areas in the districts of Howrah, Hooghly, North 24 Parganas and South 24 Parganas”
  • We could not verify which licensee serves Sector V or New Town. Read the name on the landlord’s electricity bill

The request

  • Ask the licensee in writing for an estimate, on the form the regulations provide
  • Its quotation follows an inspection, within 14 days of a complete request in an urban area for low and medium voltage supply, and within 30 days at 11 kV

The time limits

  • Where the existing service can carry the load, or needs augmentation with no additional pole and no more than 100 metres of underground cable: 30 days for a consumer on an overhead line, 45 days where underground cable is augmented
  • Where the distributing main is augmented or a line or cable extended: 45 to 90 days for low and medium voltage consumers, by case, and 180 days for high and extra high voltage consumers
  • Each runs from receipt of the application form, completed in every respect. Where a new transformer or bay has to be commissioned in an existing substation, the limit is 90 days for a distribution substation and 150 or 270 days for the two larger classes. A new substation follows a separate regulation that we did not read

What the fit-out adds

  • The load to apply for comes from the electrical design: each DB panel, its MCBs, MCCBs and RCCBs (circuit breakers), the conduit and the earthing
  • HVAC plant is usually the largest item: AHUs or FCUs (air handling or fan coil units) on a building chiller, or outdoor units on a floor’s own VRF system
  • Set the 14 days and the 30 or 45 days against that plant’s lead time

Signage

Does an office signboard in Kolkata have to carry Bengali?

Inside the Corporation’s limits a municipal order puts Bengali at the top of every signboard.

What the Corporation ordered

  • An office order of 30 December 2024 made it “mandatory to include the Bengali Language on top of all signboards, hoardings and signage, alongside any other languages”. It lists companies and offices
  • A circular of 30 August 2025 repeated that signage “must have Bengali displayed at the top in a prominent size”, by 30 September 2025

What the papers leave out

  • Neither names a penalty or a section of law, and “a prominent size” is the only instruction on size
  • We found nothing comparable for Sector V or New Town

On your signs

  • A sign in acrylic letters on an ACP (aluminium composite panel) tray is costly to remake, so check the Bengali line on the proof, starting with the entrance fascia
  • IBS’s print branding line makes reception logo walls, glass film, wall graphics, wayfinding signs and cabin name plates alongside the interior

Building status

Is the building a declared heritage building, or the floor inside a special economic zone?

Two questions for the landlord before design starts.

A declared heritage building

  • The Corporation’s Act obliges the owner or occupier of a building it has declared a heritage building to maintain, preserve and conserve it
  • Changes to such a building, its internal walls, floor, roof and interior included, come under the Act’s building chapters and their rules. We would not rely on the no-permit list for gypsum partitions there
  • We did not read the Corporation’s heritage list, so the landlord has to confirm the status

A special economic zone

  • The Government’s list of operational special economic zones (SEZs), up to 31 March 2026, has rows at Rajarhat and at Action Area-II, New Town. No IT row names Sector V
  • The developer and your lease settle whether a floor is inside one. Ask before the BOQ is priced

Market data

What do JLL and Cushman & Wakefield publish about Kolkata offices?

Each number carries its firm’s name, and none is an IBS price.

By district (Cushman & Wakefield, Q3 2026, Grade A only)

  • Central business district (CBD): 1,872,454 sq ft, 18.7% vacant, ₹110.1 per sq ft a month
  • Sector V, Salt Lake: 13,009,650 sq ft, 10.1% vacant, ₹55.0
  • Rajarhat: 10,587,434 sq ft, 5.2% vacant, ₹50.0, with 3,158,143 sq ft planned or under construction
  • City total: 27,593,578 sq ft and 9.5% vacant. Sector V and Rajarhat took 95% of the quarter’s 0.58 million sq ft of leasing
  • Our arithmetic: those two hold 85.5% of the stock and the CBD 6.8%

Leasing in 2025

  • 1.6 million sq ft of gross leasing, against 1.7 million in 2024, printed as -9.2% (JLL India, January 2026)

Fit-out cost (Cushman & Wakefield, March 2026)

  • ₹5,847 per sq ft in Kolkata for a collaborative hybrid workplace, a rank shared with Ahmedabad, Chennai, Hyderabad and Pune
  • The guide prints one figure for the city, while CBD rent is 2.2 times Rajarhat’s (110.1 ÷ 50.0). IBS prices each floor from a site survey and a BOQ

Have a Kolkata floor in mind?

Send the building and its district, the carpet area, your headcount and your move-in date, with the building’s fire NOC if the landlord will share it. IBS carries out a site survey, then prices a line-item BOQ.

Questions Buyers Ask

Frequently asked questions

Who are the best office interior designers in Kolkata?
We found no neutral ranking, so compare firms on what you can verify: whether the firm that draws the office also builds it, whether the tradesmen are its own staff, and how large its biggest order was. IBS designs in-house and builds the MEP, HVAC and fire fighting with its own engineers and workmen. Its largest single order is ₹25 Crore.
Does IBS have a team in Kolkata?
Yes. IBS has a local presence in Kolkata, and its local teams carry out the site survey and the work on your floor. It is a national contractor that executes projects across India, with local teams in the major cities, Tier 2 and Tier 3 cities included.
Which authority approves building work for an office in Salt Lake Sector V or New Town?
The Nabadiganta Industrial Township Authority for Sector V, and the New Town Kolkata Development Authority for New Town. Nabadiganta says so on its website, and New Town’s Act of 2007 requires that authority’s previous sanction. We read no interior-work rules for either, so ask in writing before gypsum partitions start.
Do we need a building permit to put up partitions in a Kolkata office?
Inside the Kolkata Municipal Corporation’s limits, the 2009 Building Rules require no building permit for an internal partition wall that does not violate the Act or the rules. It still needs fifteen days’ written notice to the Municipal Commissioner. If your layout divides one office into several, ask the Corporation in writing.
Is the landlord or the tenant responsible for fire safety in a leased Kolkata office?
Both. The West Bengal Fire Services Act makes the owner of a high-risk building provide its fire safety measures and the occupier maintain them, and a tenant liable to pay rent is an occupier. The Act forbids altering fire safety equipment, so get the landlord’s written agreement before moving sprinkler heads or smoke detectors.
How long is a Fire Safety Certificate valid in West Bengal, and how long does an application take?
Three years from its date of issue, under a 2018 amending Act whose commencement notification we did not find. A department order of 9 December 2025 calls the term usually three years. An application has a time limit of 15 days in KMC areas and 30 days in the rest of West Bengal.
Does a small office in Kolkata need a fire NOC?
A 2024 notification takes offices up to 15.5 metres in height and up to 500 sq m in total floor area, both together, out of the high-risk class. They upload a yearly self certification and need no Fire Safety Certificate, often called a fire NOC. Whether a small floor in a taller tower qualifies we could not establish, so ask the fire service.
What hours can trucks deliver fit-out material to an office in Kolkata?
At night, for the lorries that carry gypsum board, plywood and HVAC plant. Kolkata Police restricts heavy and medium goods vehicles from 06.00 to 22.00 hours daily across the city, except in the port area. Light goods vehicles may move from 12.00 to 16.00 and from 22.00 to 06.00. We read no order covering Sector V and New Town.
Does Durga Puja stop an office fit-out in Kolkata?
The papers we read restrict deliveries and say nothing about private sites. For 2026, Kolkata Police’s notification prohibits all goods vehicles within the city in daily blocks from 13 October to 5 am on 25 October. The State’s holiday list binds banks and government offices. Read each year’s notification.
Does our office signboard in Kolkata have to be in Bengali?
Inside the Kolkata Municipal Corporation’s limits, an office order of 30 December 2024 makes Bengali mandatory at the top of all signboards, hoardings and signage, and it names companies and offices. It cites no penalty and no statute. We found nothing comparable for Sector V or New Town. Check each sign proof for it.
Which electricity company supplies an office in Kolkata, and how long does extra load take?
CESC Limited is a distribution licensee for Kolkata metro and some areas in four other districts. For Sector V or New Town, read the landlord’s bill, because we could not verify the licensee. Where the existing service can carry the extra load for HVAC plant, the time limit is 30 days on an overhead line, or 45 where underground cable is augmented.
What do office interior designers typically charge in Kolkata?
Cushman & Wakefield’s 2026 fit-out cost guide prints ₹5,847 per sq ft for a collaborative hybrid workplace in Kolkata. That is market data for a whole fit-out. IBS publishes no rate. After a site survey it prices a line-item BOQ (bill of quantities), with design as a line of its own.
Is IBS on the approved-vendor lists of large companies?
Yes. IBS is an approved vendor at Adani Airports, HDFC ERGO, Reliance Retail, Godrej Finance, EPSON, Duravit, HSBC, Tata CLiQ, Canon, Aditya Birla Fashion and Retail and HDFC Life. It is also cleared by BCAS, the Bureau of Civil Aviation Security, to work across the entire airport premises, airside included.
Which company is best for interior design when Kolkata is one of several offices?
No ranking answers that, so look at whom a firm already works for and where its people are. IBS is a national contractor with local teams in India’s major cities, Kolkata among them. Its enterprise clients include Adani Airports, Reliance Retail, Tata CLiQ, Aditya Birla Fashion and Retail, GroupM, Belgian Waffle, EPSON, Canon, Planet Retail, Society Tea and Duravit.
Are there turnkey interior contractors in Kolkata who design and build under one contract?
IBS works that way where a client has no architect. Its in-house team designs the interior, MEP, HVAC and fire fighting, and its own engineers and workmen build them under one contract. Where an architect has drawn the office, IBS builds from the architect’s GFC drawings, issues shop drawings before fabrication and does not compete for the design.
How do we get a quote for office interior design in Kolkata?
Send the building and its district (central business district, Sector V or New Town), the carpet area, your headcount and the move-in date, by the enquiry form, WhatsApp or email. Add the building’s fire NOC if you have it. IBS carries out a site survey, then prices a line-item BOQ.
