# House Construction Cost Planning: Yuen Long, Hong Kong SAR, China > Yuen Long house cost planning using the World Bank ICP 2021 national construction price-level index of 141.8, plus a GeoNames-based local comparable-search shortlist. - Canonical: https://harth.build/resources/construction-costs/house-construction-cost-yuen-long-hk/ - Last updated: 2026-09-15 - Data source: 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 1818225). The PLI is not a city cost/m² rate, current escalation series or tender estimate. ## Key facts | Fact | Value | | --- | --- | | National construction PLI | 141.8 (World Bank ICP 2021; World = 100) | | Screening ratio to world | 1.418 (dimensionless PLI ÷ 100; not a city location factor) | | Locality reference | 22.4452, 114.0262 (GeoNames ID 1818225) | | Snapshot population | 200,000 (18 of 50 listed Hong Kong SAR, China places) | | Nearest listed peer | Yuen Long Kau Hui · 1 km (great-circle distance between GeoNames reference points) | | Estimate currency | HKD (obtain a current local rate and named base date) | ## Direct answer For early house construction cost planning in Yuen Long, 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 Yuen Long 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 Yuen Long market basket or current house tenders. GeoNames 1818225 records the locality at 22.4452, 114.0262, with snapshot population 200,000. That ranks Yuen Long 18 of 50 listed places, while Yuen Long Kau Hui is the nearest listed peer at about 1 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. *Content and cited inputs reviewed by [Scott Barrington](https://nz.linkedin.com/in/barrington), Harth founder and architectural technology specialist · Published 2026-08-26 · Updated 2026-09-15.* ## What does the 141.8 construction index mean? The World Bank ICP 2021 construction PLI for **Hong Kong SAR, China is 141.8**, compared with a world benchmark of 100. It is a national spatial price comparison assembled for the 2021 reference year. It does not say that house work in Yuen Long costs 1.418 times a current world rate. ## Which Yuen Long inputs are known? The reproducible locality point is **22.4452, 114.0262** (GeoNames 1818225). Its snapshot population is **200,000**, ranked 18 of 50 listed places; GeoNames classifies it as a first-order administrative seat in administrative area NYL. These facts shape the local comparable search, not the price. ## What must a project estimate add? For a Yuen Long house project, reconcile dwelling size, structural system, envelope specification, kitchens and bathrooms. Use a consistent gross-floor-area basis and record the following before reliance. | Estimate field | Screening record | Project requirement | | --- | --- | --- | | National context | ICP 2021 PLI 141.8 | Retain only as dated cross-country context | | Local HKD/m² rate | Not supplied | Current comparable with named source and base date | | Area and scope | Gross floor area; scope unresolved | Measurement standard, specification and procurement route | | Additions | Not supplied | Taxes, fees, site work, contingency and escalation | | Review | Automated source and arithmetic QA | Qualified local cost review | ## Yuen Long comparable-location search screen This shortlist is computed from the checked GeoNames snapshot. Distance and population help prioritize where to request comparables; neither is used as a cost multiplier. | Listed place | Great-circle km from Yuen Long | Snapshot population | Admin area | | --- | ---: | ---: | --- | | Yuen Long Kau Hui | 1 | 169,600 | NYL | | Yuen Long San Hui | 2 | 200,000 | NYL | | Ping Shan | 2 | 45,400 | NYL | | Shap Pat Heung | 2 | 77,775 | NYL | | Tin Shui Wai | 3 | 286,232 | NYL | | Kowloon City Centre | 21 | 194,290 | KKC | | Ma On Shan | 22 | 215,200 | NST | | Tsing Yi Town | 13 | 182,100 | NKT | ## 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 Yuen Long adjustment | Not asserted | Replace with current local comparable evidence | | Result status | Screening normalization | Not a budget, quote or tender estimate | ## Where can you explore related guidance? - [Explore all construction costs guidance](https://harth.build/resources/construction-costs.md) - [Office Construction Cost Planning: Yuen Long, Hong Kong SAR, China](https://harth.build/resources/construction-costs/office-construction-cost-yuen-long-hk.md) - [School Construction Cost Planning: Yuen Long, Hong Kong SAR, China](https://harth.build/resources/construction-costs/school-construction-cost-yuen-long-hk.md) - [Retail Construction Cost Planning: Yuen Long, Hong Kong SAR, China](https://harth.build/resources/construction-costs/retail-construction-cost-yuen-long-hk.md) - [House Construction Cost Planning: Yuen Long Kau Hui, Hong Kong SAR, China](https://harth.build/resources/construction-costs/house-construction-cost-yuen-long-kau-hui-hk.md) - [All construction costs guidance for Hong Kong](https://harth.build/resources/construction-costs/hong-kong.md) - [Daylight & Orientation: Yuen Long, Hong Kong](https://harth.build/resources/solar-data/daylight-orientation-yuen-long-hk.md) - [Solar Altitude & Azimuth: Yuen Long, Hong Kong](https://harth.build/resources/solar-data/solar-altitude-azimuth-yuen-long-hk.md) - [Solar Shading Design: Yuen Long, Hong Kong](https://harth.build/resources/solar-data/solar-shading-design-yuen-long-hk.md) - [Sun Path: Yuen Long, Hong Kong](https://harth.build/resources/solar-data/sun-path-yuen-long-hk.md) ## Sources and method 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 1818225).

No. 141.8 is the World Bank ICP 2021 national construction price-level index for Hong Kong SAR, China, with the world equal to 100. It is a cross-country screening statistic, not a Yuen Long HKD/m² rate, escalation index, quote or tender estimate. ### How should a Yuen Long house estimate replace this screening benchmark? Collect current Yuen Long comparables on a consistent gross-floor-area basis, reconcile dwelling size, structural system, envelope specification, kitchens and bathrooms, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fconstruction-costs%2Fhouse-construction-cost-yuen-long-hk%2F - View this page in a browser: https://harth.build/resources/construction-costs/house-construction-cost-yuen-long-hk/ - All resources for agents: https://harth.build/llms.txt
