Indias Office Market Is Growing, but Flex Space Is Doing Most of the Heavy Lifting

India’s office-leasing headline looks broadly positive.

Grade A gross leasing reached 54.4 million sq ft during the first nine months of 2026, up 7% year-on-year, while Q3 leasing increased 9% to 18.7 million sq ft.

Bengaluru remains the largest office market and Delhi-NCR has accelerated sharply.

But the more important change is happening inside the leasing mix.

Flex-space operators accounted for 12.6 million sq ft of January-September leasing, up 37%, while conventional office leasing was almost flat.

That means much of the market’s reported growth is coming from a different type of occupier.

The headline market grew by 3.5 million sq ft

Colliers reports total leasing of:

• 50.9 million sq ft in January-September 2025
• 54.4 million sq ft in January-September 2026

That is an increase of approximately 3.5 million sq ft.

Over the same period:

• conventional leasing increased from 41.7 million to 41.8 million sq ft;
• flex-space leasing increased from 9.2 million to 12.6 million sq ft.

Flex therefore added approximately 3.4 million sq ft of leasing, while conventional demand added only around 0.1 million sq ft.

Based on those rounded figures, roughly 97% of the net year-on-year increase in leasing came from flex-space operators.

This is a Vantage editorial calculation, not a Colliers-published metric.

Because the source figures are rounded, the percentage should be treated as directional rather than exact.

Q3 shows the same pattern

The quarterly data point in the same direction.

Total Q3 leasing increased from 17.2 million sq ft to 18.7 million sq ft, an increase of approximately 1.5 million sq ft.

Flex leasing increased from 2.7 million to 4.0 million sq ft.

Conventional leasing increased from 14.5 million to 14.7 million sq ft.

On the rounded data, flex therefore accounted for roughly 87% of the net year-on-year increase in Q3 leasing.

Again, this is an editorial calculation rather than a source-published indicator.

The implication is not that conventional offices are disappearing.

Conventional space still represented 77% of nine-month leasing.

The more precise signal is that flex is currently providing most of the incremental growth.

Why that distinction matters

A conventional corporate office lease and a lease signed by a flex-space operator are not economically identical.

In a conventional transaction, the corporate occupier typically leases the office directly.

In a flex transaction, the workspace operator may first take the space from a landlord and subsequently sell desks, suites or managed offices to multiple end users.

That creates an additional layer between the property owner and the companies actually using the space.

For landlords, flex operators can provide large leasing commitments.

For companies, flex formats can provide faster access to fitted space and more adaptable capacity.

But there is an important caveat:

space leased by a flex operator should not automatically be treated as fully occupied by end users.

Operator-level leasing and end-user occupancy are separate metrics.

The accessible Colliers release does not disclose portfolio-level occupancy of the flex operators included in its leasing totals.

Bengaluru still provides the scale

Bengaluru recorded 15.7 million sq ft of leasing during January-September, representing 29% of total demand.

Its Q3 leasing reached 5.2 million sq ft, up 11% year-on-year.

Colliers notes that Bengaluru has averaged roughly 5 million sq ft of quarterly leasing since 2025.

The city therefore remains the benchmark market for office scale.

Vantage previously examined one of the structural drivers behind this demand in GCC expansion could take India's next office boom beyond major cities.

That coverage highlighted how GCCs have become an increasingly important source of large-format office leasing.

For Bengaluru, the question is no longer simply whether it can generate demand.

It is whether infrastructure, available Grade A stock, rents and talent-market constraints can keep supporting leasing at this scale.

Delhi-NCR is the market to watch

Delhi-NCR’s Q3 numbers show the sharpest change.

Leasing increased from 1.6 million sq ft in Q3 2025 to 3.3 million sq ft in Q3 2026, a 106% increase.

Nine-month leasing reached 8.3 million sq ft, up 17%.

Delhi-NCR was also one of India’s two largest flex markets, alongside Bengaluru, with 2.8 million sq ft of flex leasing during January-September.

Colliers says flex uptake in Delhi-NCR more than doubled year-on-year.

This combination matters.

Delhi-NCR is not only recording more office leasing overall; flex operators are also expanding rapidly within that market.

For developers and landlords, that increases the importance of understanding whether future demand is coming from direct occupiers, GCCs or workspace operators.

Hyderabad tells a different story

Hyderabad recorded 9.4 million sq ft of leasing during January-September, up 47% year-on-year.

Yet Q3 leasing fell 42% sequentially to 2.2 million sq ft after a particularly strong Q2.

The city therefore illustrates why office leasing can be volatile from quarter to quarter.

Large transactions can move city totals significantly.

A single-quarter decline does not necessarily imply deteriorating underlying demand when the nine-month number remains substantially above the previous year.

Conventional office demand is still highly concentrated by sector

Technology companies accounted for close to 16 million sq ft of conventional office leasing during the first nine months.

Technology, BFSI and engineering and manufacturing firms together generated nearly three-fourths of conventional leasing.

Bengaluru and Hyderabad together represented more than 55% of technology-sector conventional demand.

Mumbai, meanwhile, accounted for 30% of BFSI conventional leasing.

This tells landlords something important:

the office market may be growing nationally, but the relationship between city, occupier sector and building type remains highly specific.

What this means for developers

Developers should avoid treating the 7% national leasing increase as a uniform signal.

The more useful questions are:

• Is demand in the target micro-market conventional or flex-led?
• Which occupier industries dominate?
• Are large GCC transactions supporting demand?
• How much competing Grade A supply is completing nearby?
• What proportion of flex-leased space is subsequently occupied by end users?

The answer can differ sharply between Bengaluru, Delhi-NCR, Hyderabad, Mumbai and Chennai.

What this means for landlords

Flex operators can accelerate lease-up of large office blocks.

But landlord underwriting should still consider operator strength, lease structure, security deposits, fit-out economics and end-user occupancy.

A large operator lease can improve headline occupancy while introducing a different tenant-risk profile from a direct lease with a large corporate occupier.

What this means for investors

Strong leasing is supportive for institutional office ownership, but gross leasing alone does not determine investment returns.

Vantage’s Six listed Indian REITs distribute Rs 3,136 crore to investors in Q1 FY27 provides a related view of the commercial-property market through listed REIT cash flows.

For an individual office asset or REIT, investors still need to assess:

• occupancy;
• rent reversions;
• lease expiries;
• tenant concentration;
• debt;
• acquisition pricing; and
• asset quality.

Supply versus leasing needs careful interpretation

New office supply reached 41.7 million sq ft during January-September 2026, up around 1% year-on-year.

That is below the reported 54.4 million sq ft of gross leasing.

It may be tempting to interpret the difference as 12.7 million sq ft of inventory being removed from the market.

That would be incorrect.

Gross absorption can include occupiers relocating from one building to another, so it is not equivalent to net absorption.

The figures therefore do not establish how much vacancy changed.

City-level vacancy data would be required to answer that question properly.

The market is growing, but the composition is changing

The strongest conclusion from the nine-month office data is not simply that demand increased 7%.

It is that incremental leasing growth is being driven overwhelmingly by flex-space operators, while conventional demand remains broadly stable.

At the same time, the geography is shifting.

Bengaluru remains the scale leader.

Delhi-NCR is accelerating.

Hyderabad remains strong on a nine-month basis despite quarterly volatility.

For developers and investors, the next phase of the office cycle may therefore depend less on the national leasing headline and more on who is leasing, where they are leasing and how those spaces ultimately get occupied.

What to watch next

The most useful indicators for Q4 and 2027 will be:

• flex operator leasing versus end-user occupancy;
• GCC leasing volumes;
• conventional office growth;
• city-level vacancy;
• rental growth;
• new completions;
• large-format transaction activity; and
• Delhi-NCR’s ability to sustain its Q3 acceleration.

Without those measures, the national gross-leasing figure provides only part of the office-market picture.

Evidence Caveats

The analysis uses Colliers’ definition of Grade A gross absorption across seven office markets.

The approximately 97% nine-month contribution and 87% Q3 contribution attributed to flex leasing are Vantage editorial calculations using rounded source figures.

They describe the contribution of flex leasing to the change in gross leasing, not flex’s share of the entire market.

Flex operator leasing also does not establish end-user occupancy.

The following data were unavailable in the reviewed source material:

• flex operator end-user occupancy;
• city-level vacancy;
• micro-market-level rental growth;
• complete tenant-level leasing transactions;
• asset-level rent and incentive packages; and
• net absorption by city.
