Bangkok Office Vacancy & Occupancy — July 2026
How much office space is empty in Bangkok?
As of Jul 2026, about 85.2% of Bangkok office space is already rented out, leaving roughly 14.8% — around 1,290,708 sqm — still available to rent, out of 8,713,238 sqm across 302 buildings.
- 85.2% "occupied" = the share of space that already has a tenant. The higher it is, the fuller the market.
- 1,290,708 sqm = the actual empty office space you can still rent right now.
This is an estimate from the 302 buildings we track (271 of them currently have empty space) — not a survey of every office building in Bangkok.
Key findings
- Estimated occupancy is about 85.2%, leaving roughly 1,290,708 sqm of verified available space.
- Among the same 203 buildings tracked every year (like-for-like), available space increased from 570,277 sqm (2016) to 1,165,340 sqm (2025) — about 104% over the decade.
- Rama 4 has the most available space (226,347 sqm).
- Krung Thonburi is the most tightly occupied (98.1%); Rama 4 has the most slack (71%).
Whole market: occupied vs vacant space, and the vacancy rate 2016–2025
Bars = total space each year, in 4 layers · lower zone = occupied (dark navy = base stock, light blue = added since) · upper zone = vacant (pink = base, red = added) · orange line = vacancy rate % (right axis). Key point: the occupied (navy) zone keeps GROWING, but the vacant zone grows faster — so the vacancy rate rose from 9.9% to 32.2% (~10% healthy; over 20% oversupplied). The market loosened because supply grew faster than demand, not because tenants fled. Absolute figures reflect buildings surveyed each year.
"Base stock" = buildings open on/before 2016; "added since" = supply completed after 2016 (a fixed group, not "new" forever).
| Year | Base stock | · vacant | Added since | · vacant | Total | Vac. rate |
|---|---|---|---|---|---|---|
| 2016 | 2.80M | 0.29M | 0.30M | 0.02M | 3.10M | 9.9% |

Why did market occupancy fall? — market vs like-for-like vs added supply
Market occupancy fell from 90% to 68%, but like-for-like (the same 175 buildings with full data every year) fell only 89% → 78%, while added supply sits lowest (95% → 61%). The takeaway: the market drop is driven by new supply still leasing up — not existing buildings emptying out (they hold at 78%).
| Year | Market | Like-for-like | Added supply |
|---|---|---|---|
| 2016 | 90% | 89% | 95% |
| 2017 | 91% | 91% | 97% |
| 2018 | 92% | 91% | 94% |
| 2019 | 90% | 91% | 82% |
| 2020 | 86% | 89% | 74% |
| 2021 | 81% | 86% | 72% |
| 2022 | 79% | 85% | 70% |
| 2023 | 76% | 84% | 68% |
| 2024 | 70% | 80% | 61% |
| 2025 | 68% | 78% | 61% |
Where is the vacancy now — by building age
Bars = each age group's share of all vacant space · right badge = that group's occupancy (green = nearly full, amber = mid, red = loose). Note: a group can hold a lot of vacancy simply because it has many buildings — check occupancy too, not just the bar.

*Estimated occupancy = 1 − verified vacant space ÷ net leasable area of the buildings in this dataset. It is an estimate from the buildings we track, not a census of every Bangkok office building. The "Buildings" column shows how many buildings each area's figures rest on — areas with only a few buildings should be read with caution.
What rising vacancy means
Across the like-for-like panel — the same buildings tracked every year — available space increased by about 104% over the decade while weighted rent stayed close to flat (see the rent page). These same buildings emptied even though none were added — usually explained two ways: (1) as better new buildings opened elsewhere, some tenants moved out of this older stock into them (flight to quality), and (2) hybrid working trimmed the space tenants need — though how much each contributes is hard to isolate.
For building owners: more competing space means pricing power sits with tenants; differentiation (flexible terms, building upgrades and better service) matters more than headline rent. Older stock feels it first as flight-to-quality pulls tenants to newer buildings.
For tenants: more choice and more leverage — a good window to negotiate the rent, a rent-free fit-out period and other lease terms, especially where local availability is high.
How we measure
Estimated occupancy = 1 − verified available area ÷ net leasable area (NLA), clamped to 0–100%, computed across the 302 active buildings with area data (out of 365 in the database). The available space comes straight from each building's current vacancy listing — the same data shown on its page — and updates on a rolling basis as we refresh buildings, so figures reflect the latest listing updates (through Jul 2026), not a single fixed-date survey.
The trend Index uses a like-for-like panel: only the 203 buildings surveyed every December from 2016 to 2025, indexed to 2016 = 100, so coverage growth doesn't distort the trend. Each building's verified vacant space is counted once per survey; years with no survey appear as a gap.

Data limitations
- Not a census of every Bangkok building; covers buildings we track.
- Occupancy is estimated from verified vacant space, not a landlord-reported figure.
- NLA (net leasable area) is not available for every building; areas missing it are excluded from occupancy.
- Availability reflects listed vacant space and can lag very recent moves in or out.
FAQ
What is the office occupancy rate in Bangkok?
As of Jul 2026, Bangkok office space is about 85.2% occupied (an estimate from the buildings we track), leaving roughly 1,290,708 sqm available across 302 buildings. This is verified available space, not a full market census.
How is estimated occupancy calculated?
Estimated occupancy = 1 − verified vacant space ÷ net leasable area of the buildings in our dataset. It reflects the buildings OfficeBangkok tracks, not every office building in Bangkok.
Which area has the most available office space?
Rama 4 has the most available space (226,347 sqm), while Krung Thonburi is the most tightly occupied (98.1%). See the by-area table above.
Is this a landlord or a tenant market?
Available space increased by about 104% across the like-for-like panel since 2016 while rents stayed roughly flat. The more empty space there is, the more choice and negotiating room tenants have, especially in older stock.
