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. Net absorption 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.
