What an office interior fit-out costs in Bengaluru, and why estimates differ

How much does an office fit-out cost per sq ft in Bengaluru?

The fit-out figures published for Bengaluru and India’s other big office markets differ several-fold, because each one measures a different job.

Operators building their own centres at scale sit near the bottom of the range. Consultants pricing an occupier’s finished workplace, furniture and fees included, sit near the top.

Which published figure fits your situation?

Use the source that matches the job you are actually planning:

• You will lease space and fit it out yourself. Start from the consultants’ benchmarks for a corporate office, from Cushman & Wakefield, Colliers or Knight Frank, at the specification you want. Then check what your floor already has (what each stage includes).
• You are comparing fit-out quotes. Use the fit-out firms’ bands only as a sense check, and compare the quotes item by item with the quote checklist.
• You are taking a managed office. The operator’s cost of building usually sits inside your monthly fee. Compare fees, terms and what each fee covers instead (how managed offices pay for the fit-out).

Why do the estimates differ so much?

Published estimates differ mostly because they count different things. Six questions explain nearly every gap: how much is built, to what specification, what is included, who is building, on what area, and when.

• How much is built. A fit-out on a bare-shell floor must add services that a warm-shell or Cat A floor already has. JLL’s 2026 benchmarks, for example, price Cat B work and leave Cat A out (what each stage includes).
• To what specification. Finishes, the number of enclosed rooms and the technology move the price within any one source.
• What is included. Furniture, IT, AV, design fees and project management sit inside some figures and outside others (which figures include furniture and IT). JLL’s figures also exclude taxes and permits, so ask whether any figure includes GST (how GST applies).
• Who is building. Operators build many centres to standard designs. Samco’s IPO note credits Smartworks’ lower figure to scale and area efficiency. CBRE adds that operators may hold fit-out inventory and well-negotiated vendor contracts, because they build offices for many clients.
• On what area. CBRE’s figure is per sq ft of leasable area, which includes a share of the building’s common areas. The fit-out firms quote per sq ft of carpet area, so the same spend looks higher on their basis (which area you are being quoted).
• When. The figures date from 2024 to 2026, and JLL and Cushman & Wakefield both report fit-out costs rising over the past year, so older figures understate today’s prices.

Shell, warm shell, Cat A and Cat B: what’s in each?

Shell, warm shell, Cat A and Cat B describe how finished a floor is before your fit-out begins. The less the building already has, the more your fit-out must build, and the more it costs.

The definitions follow Brigade Group, a Bengaluru developer (June 2025), and the property consultant Savills (July 2023). JLL’s benchmarks, which price Cat B work, include builders’ works, mechanical and electrical services, furniture, security, IT, AV, preliminaries (the contractor’s site costs) and professional fees.

The labels overlap in practice: one landlord’s warm shell can include part of what another calls Cat A. Ask for the handover specification, item by item, before you compare fit-out quotes. Some operators start from a bare shell: Smartworks, for example, typically leases entire or large bare-shell buildings and fits them out itself, according to Samco’s IPO note. Short definitions of these and other terms are in the office glossary.

What drives the cost of your fit-out?

The floor you start from, the area, the number of enclosed rooms, the building services and the technology drive most of a fit-out’s cost. Special rooms, approvals and late changes add to it.

What moves your own number:

• The floor you start from. A bare shell needs services and ceilings before any layout; a warm-shell or Cat A floor already has some of them (what each stage includes).
• Area and density. Costs are quoted per sq ft, so the area sets the scale. A denser layout needs more desks, power points and data points in the same space (how much space you need).
• Cabins and meeting rooms. Each enclosed room needs walls or glass, its own lighting and air conditioning, and often AV. Cushman & Wakefield’s dearer tiers assume more of the floor goes to meeting space, and Sevantay Realty’s mid-range band is where glass cabins and meeting rooms first appear.
• Mechanical and electrical services. Extra cooling for a server room or a 24x7 area, more power points and more backed-up circuits all add cost.
• Technology. Structured cabling, Wi-Fi, video-conferencing rooms, access control and CCTV.
• Special rooms and branding. A server room, reception, pantry, phone booths and signage.
• Approvals. The building owner’s approval of your drawings, and any permits, take time as well as money.
• Changes. A change after work starts costs more than the same change on paper, so settle the layout before construction.

How long does it take to fit out and set up an office in Bengaluru?

A ready office is quickest to set up, a custom-built office takes weeks to months, and a new built-to-suit building takes years. Each published timeline also starts its clock at a different point.

How to read these timelines:

• They are mostly operators’ own claims. Smartworks, WorkEZ and Table Space publish them to sell their offices; Colliers and Brigade Group describe conventional fit-outs.
• Ask when the clock starts. It may start at signing, at possession of the space, or when you sign off the layout. WorkEZ counts from contract signing and Smartworks from sign-off of the requirement.
• Check whether finding the building is included. WorkEZ and Smartworks quote for offices built inside centres they already run. If your office needs a building found and leased first, add that time.
• Ask what happens if handover slips. Get the milestones, and any remedy for a late handover, written into the agreement.

How do managed offices pay for the fit-out?

In a managed office, the operator usually pays for the fit-out and earns it back through your monthly fee over the term.

CBRE’s 2025 report on India’s flexible workspace market says the operator usually invests the upfront capital to build the office. Clients can then avoid that outlay.

Because the cost is recovered month by month, offices built for one client tend to carry longer minimum terms. The arithmetic is worked through in why built offices carry longer terms, and lock-in, deposit and exit covers the rest of the agreement.

Nestoo designs and fits out every office for the team that will use it, then runs it day to day: see how built-to-suit works. How the fit-out cost is handled, and the term that goes with it, are set out in your proposal.

What should a fit-out quote include?

A fit-out quote should show what will be built, to what standard, by when and for how much. Use this list to compare quotes item by item, whoever prepares them.
