Bangkok Office Market — Vacancy, Rent & Trends
This page is a quick snapshot of the whole Bangkok office market. As of Oct 2026, we track 301 buildings; about 84.5% of their space is already rented out (roughly 1,346,830 sqm is still empty and available), and a typical building rents for around ฿650/sqm/month.

As of Oct 2026. OfficeBangkok's database holds 368 active buildings; 301 have complete NLA data used for the occupancy calculation. Occupancy is an estimate from verified available space (1 − available ÷ NLA); rent is asking rent, area-weighted. Vacancy totals are rounded. "Available units" counts listed vacant spaces (a building can have several).
Key findings
- In the like-for-like panel — the same 203 buildings tracked every year — verified available space increased from 570,277 sqm in 2016 to 1,165,340 sqm in 2025 — about 104%.
- Over the same period, weighted asking rent increased from ฿712 to ฿764/sqm/month — about 7%.
- Available space grew far faster than rent, indicating some landlords have not cut asking rents in line with rising vacancy.
- Rama 4 has the most available space, about 236,127 sqm, and among the highest weighted rents (฿1,186/sqm/month).
- Krung Thonburi has the highest estimated occupancy (~98.1%), though it is a smaller market than the core CBD.
- Rama 4 is among the lowest-occupancy large markets (~69.7%).
OfficeBangkok Index — 10-year trend (2016–2025)
This chart tracks the same 203 buildings every year, so it shows real change — not just our database growing. Both lines start at 100 in 2016; a line at 150 means that number is 50% higher than in 2016.
The story: the empty-space line climbs steeply while the rent line stays nearly flat — much more vacant space, but rents holding — a tenant's market.

Why vacancy increased but rent held
Much of the rise in available space came from new Grade-A supply completing after 2019, while hybrid work reduced how much space existing tenants renew. As newer, better buildings compete, occupiers move up ("flight to quality"), leaving older stock vacant.
Asking rents lag because landlords often hold headline (asking) rents and negotiate incentives instead — so the gap between asking rent shown here and effective (post-incentive) rent tends to widen in a tenant's market.
By area
Weighted rent (฿852) weights each vacant space by its size, so large Grade-A floors count more; the median (฿650) is the mid-point building rent, less affected by a few expensive towers.

For tenants
A tenant's market: more choice, and more room to negotiate the rent, a rent-free fit-out period and other lease terms (for example extra free parking) — plus a chance to upgrade to newer buildings at rents close to older stock. Compare areas before committing.
For building owners
Benchmark your building's rent and vacancy against your area here. Retention and building upgrades matter more than headline rent when newer supply is competing for the same tenants.
How we measure
Figures cover the office buildings OfficeBangkok tracks (net leasable area). "Available" is space we have verified as offered for lease; occupancy is an estimate (1 − available ÷ NLA), not a full-market census. Rents are asking rents, area-weighted. The Index uses a fixed panel of 203 buildings present every year, so it is not distorted by coverage growth. · Verified Oct 2026
Data limitations
- This is not a census of every building in Bangkok; it covers the buildings OfficeBangkok tracks.
- Figures are based on space we have verified as offered for lease.
- Rents are asking rents and exclude incentives, rent-free periods and discounts (effective rent is lower).
- Some space is offered in several sizes, and a building can list several units.
- Occupancy is therefore an estimate, not an owner-certified leased rate.

A like-for-like trend from 203 buildings tracked every year: available space and asking rent, indexed to the first year = 100. It removes coverage changes so the trend reflects the real market, not our dataset growth.
