Bangkok Office Supply — Total Stock, Grade & Age
How much office space does Bangkok have?
As of Sep 2026, we track about 8.70 million sqm of leasable office space across 301 buildings — a typical building has about 28,897 sqm, and roughly 24% of all space is in Grade-A (newer, high-ceiling) buildings.
How Bangkok office stock built up, 1982–2025
Cumulative floor area by the year each building completed (the 181 buildings with a known year) — a steeper line means more new supply opened then.
New buildings entering the market per year (2016–2025)
Over 2016–2025, about 72 new buildings added roughly 2.83 million sqm — the "new supply" side of the market.
Total stock (existing + new) vs vacancy, 2016–2025
Bars = total stock (grey = existing buildings before 2016, blue = new buildings added); red line = vacant space in the existing stock (like-for-like). In short: bars rise from new supply while the red line also climbs — stock is growing faster than it fills.

The largest buildings
How we measure
"Total NLA" sums the net leasable area of the tracked office buildings with complete area data (301 buildings). Grade uses a proxy (ceiling ≥ 2.9m and built ≥ 2016). The by-decade split and cumulative chart use only the 181 buildings with a known completion year. This is the stock we track, not a census of every building in Bangkok. · Verified Sep 2026FAQ
