Last updated September 15, 2026 · National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/HKG/classification/PX.WL/series/1501200/time/YR2021/data?format=json) and [ICP data documentation](https://www.worldbank.org/en/programs/icp/data); locality and population from the [GeoNames HK dump](https://download.geonames.org/export/dump/HK.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 12747064). The PLI is not a city cost/m² rate, current escalation series or tender estimate.
Direct answer
For early house construction cost planning in Hong Kong Island, the World Bank ICP reports a 2021 Hong Kong SAR, China construction price-level index of 141.8, with the world equal to 100. This is a national comparison—not a Hong Kong Island HKD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Hong Kong SAR, China in 2021; it does not measure a Hong Kong Island market basket or current house tenders. GeoNames 12747064 records the locality at 22.2630, 114.1842, with snapshot population 1,195,529. That ranks Hong Kong Island 4 of 50 listed places, while Hong Kong is the nearest listed peer at about 2 km. Use these facts only to plan the comparable search. Obtain current local rates on a consistent area basis, then reconcile scope, taxes, fees, contingency and escalation. Retain the source, base date and reviewer when local evidence replaces the screening ratio.

Price-level normalization worksheet
For a validated reference rate R from a country with construction PLI P, the transparent screening calculation is R × (141.8 ÷ P). At P = 100 the dimensionless ratio is 1.418; no world cost rate is asserted. Keep the reference rate's currency, base date, area basis and scope attached.
| Input | Recorded value | Release condition |
|---|---|---|
| Target national PLI | 141.8 (World = 100, 2021) | Screening context only |
| Reference construction PLI P | User-supplied from the same ICP classification/year | Must match reference rate country |
| Validated reference rate R | User-supplied | Named source, currency, date, area and scope |
| Local Hong Kong Island adjustment | Not asserted | Replace with current local comparable evidence |
| Result status | Screening normalization | Not a budget, quote or tender estimate |
