# House Construction Cost Planning: Woodlands, Singapore > Woodlands house cost planning using the World Bank ICP 2021 national construction price-level index of 97.6, plus a GeoNames-based local comparable-search shortlist. - Canonical: https://harth.build/resources/construction-costs/house-construction-cost-woodlands-sg/ - 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/SGP/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 SG dump](https://download.geonames.org/export/dump/SG.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 1882316). The PLI is not a city cost/m² rate, current escalation series or tender estimate. ## Key facts | Fact | Value | | --- | --- | | National construction PLI | 97.6 (World Bank ICP 2021; World = 100) | | Screening ratio to world | 0.976 (dimensionless PLI ÷ 100; not a city location factor) | | Locality reference | 1.4380, 103.7888 (GeoNames ID 1882316) | | Snapshot population | 254,440 (8 of 50 listed Singapore places) | | Nearest listed peer | Sembawang Estate · 5 km (great-circle distance between GeoNames reference points) | | Estimate currency | SGD (obtain a current local rate and named base date) | ## Direct answer For early house construction cost planning in Woodlands, the World Bank ICP reports a 2021 Singapore construction price-level index of 97.6, with the world equal to 100. This is a national comparison—not a Woodlands SGD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Singapore in 2021; it does not measure a Woodlands market basket or current house tenders. GeoNames 1882316 records the locality at 1.4380, 103.7888, with snapshot population 254,440. That ranks Woodlands 8 of 50 listed places, while Sembawang Estate is the nearest listed peer at about 5 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 97.6 construction index mean? The World Bank ICP 2021 construction PLI for **Singapore is 97.6**, 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 Woodlands costs 0.976 times a current world rate. ## Which Woodlands inputs are known? The reproducible locality point is **1.4380, 103.7888** (GeoNames 1882316). Its snapshot population is **254,440**, ranked 8 of 50 listed places; GeoNames classifies it as a populated place in administrative area 03. These facts shape the local comparable search, not the price. ## What must a project estimate add? For a Woodlands 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 97.6 | Retain only as dated cross-country context | | Local SGD/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 | ## Woodlands 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 Woodlands | Snapshot population | Admin area | | --- | ---: | ---: | --- | | Sembawang Estate | 5 | 110,090 | 00 | | Yishun New Town | 5 | 228,730 | 03 | | Fajar | 6 | 26,420 | not stated | | Yew Tee | 7 | 39,100 | 03 | | Saujana | 7 | 25,000 | not stated | | Jurong West | 12 | 253,840 | 00 | | Tampines New Town | 20 | 259,900 | 00 | | Jurong Town | 14 | 262,730 | 05 | ## Price-level normalization worksheet For a validated reference rate **R** from a country with construction PLI **P**, the transparent screening calculation is **R × (97.6 ÷ P)**. At P = 100 the dimensionless ratio is 0.976; 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 | 97.6 (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 Woodlands 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: Woodlands, Singapore](https://harth.build/resources/construction-costs/office-construction-cost-woodlands-sg.md) - [School Construction Cost Planning: Woodlands, Singapore](https://harth.build/resources/construction-costs/school-construction-cost-woodlands-sg.md) - [Retail Construction Cost Planning: Woodlands, Singapore](https://harth.build/resources/construction-costs/retail-construction-cost-woodlands-sg.md) - [House Construction Cost Planning: Sembawang Estate, Singapore](https://harth.build/resources/construction-costs/house-construction-cost-sembawang-estate-sg.md) - [All construction costs guidance for Singapore](https://harth.build/resources/construction-costs/singapore.md) - [Sun Path: Woodlands, Singapore](https://harth.build/resources/solar-data/sun-path-woodlands-sg.md) ## Sources and method National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/SGP/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 SG dump](https://download.geonames.org/export/dump/SG.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 1882316).

No. 97.6 is the World Bank ICP 2021 national construction price-level index for Singapore, with the world equal to 100. It is a cross-country screening statistic, not a Woodlands SGD/m² rate, escalation index, quote or tender estimate. ### How should a Woodlands house estimate replace this screening benchmark? Collect current Woodlands 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-woodlands-sg%2F - View this page in a browser: https://harth.build/resources/construction-costs/house-construction-cost-woodlands-sg/ - All resources for agents: https://harth.build/llms.txt
