How much vacant space changed, and what it means
Rent in 2025
The two differ because the mix of surveyed buildings changes — when newer, pricier buildings enter the survey the overall average looks higher even if existing buildings did not raise rents. For trend reading, rely on the like-for-like figure.
New supply completed in 2025

Method & scope
This report is computed from the December 2025 survey of the 291 office buildings OfficeBangkok tracks — not a census of every Bangkok building. All figures count only buildings surveyed that year, so a year with thinner coverage is not flattered by a full-stock denominator. The vacancy movement and the rent change use a like-for-like panel of 284 buildings present in both December 2024 and December 2025. Rents are asking rents, weighted by vacant-space size — not effective (post-incentive) rents. Figures in this report are frozen to that survey and do not move as newer data arrives; for current numbers, see the market pages.
