# House Construction Cost Planning: Melbourne City Centre, Australia > Melbourne City Centre house cost planning using the World Bank ICP 2021 national construction price-level index of 264.1, plus a GeoNames-based local comparable-search shortlist. - Canonical: https://harth.build/resources/construction-costs/house-construction-cost-melbourne-city-centre-au/ - 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/AUS/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 AU dump](https://download.geonames.org/export/dump/AU.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 11523810). The PLI is not a city cost/m² rate, current escalation series or tender estimate. ## Key facts | Fact | Value | | --- | --- | | National construction PLI | 264.1 (World Bank ICP 2021; World = 100) | | Screening ratio to world | 2.641 (dimensionless PLI ÷ 100; not a city location factor) | | Locality reference | -37.8150, 144.9666 (GeoNames ID 11523810) | | Snapshot population | 60,057 (37 of 50 listed Australia places) | | Nearest listed peer | Melbourne · 0 km (great-circle distance between GeoNames reference points) | | Estimate currency | AUD (obtain a current local rate and named base date) | ## Direct answer For early house construction cost planning in Melbourne City Centre, the World Bank ICP reports a 2021 Australia construction price-level index of 264.1, with the world equal to 100. This is a national comparison—not a Melbourne City Centre AUD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Australia in 2021; it does not measure a Melbourne City Centre market basket or current house tenders. GeoNames 11523810 records the locality at -37.8150, 144.9666, with snapshot population 60,057. That ranks Melbourne City Centre 37 of 50 listed places, while Melbourne is the nearest listed peer at about 0 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 264.1 construction index mean? The World Bank ICP 2021 construction PLI for **Australia is 264.1**, 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 Melbourne City Centre costs 2.641 times a current world rate. ## Which Melbourne City Centre inputs are known? The reproducible locality point is **-37.8150, 144.9666** (GeoNames 11523810). Its snapshot population is **60,057**, ranked 37 of 50 listed places; GeoNames classifies it as a section of a populated place in administrative area 07. These facts shape the local comparable search, not the price. ## What must a project estimate add? For a Melbourne City Centre 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 264.1 | Retain only as dated cross-country context | | Local AUD/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 | ## Melbourne City Centre 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 Melbourne City Centre | Snapshot population | Admin area | | --- | ---: | ---: | --- | | Melbourne | 0 | 5,435,590 | 07 | | City of Port Phillip | 3 | 112,669 | 07 | | Reservoir | 11 | 51,096 | 07 | | Glen Waverley | 19 | 42,642 | 07 | | Point Cook | 22 | 66,781 | 07 | | Pittwater | 734 | 63,482 | 02 | | Tarneit | 27 | 56,370 | 07 | | Craigieburn | 24 | 65,178 | 07 | ## Price-level normalization worksheet For a validated reference rate **R** from a country with construction PLI **P**, the transparent screening calculation is **R × (264.1 ÷ P)**. At P = 100 the dimensionless ratio is 2.641; 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 | 264.1 (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 Melbourne City Centre 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: Melbourne City Centre, Australia](https://harth.build/resources/construction-costs/office-construction-cost-melbourne-city-centre-au.md) - [School Construction Cost Planning: Melbourne City Centre, Australia](https://harth.build/resources/construction-costs/school-construction-cost-melbourne-city-centre-au.md) - [Retail Construction Cost Planning: Melbourne City Centre, Australia](https://harth.build/resources/construction-costs/retail-construction-cost-melbourne-city-centre-au.md) - [House Construction Cost Planning: Melbourne, Australia](https://harth.build/resources/construction-costs/house-construction-cost-melbourne-au.md) - [All construction costs guidance for Australia](https://harth.build/resources/construction-costs/australia.md) - [Daylight & Orientation: Melbourne City Centre, Australia](https://harth.build/resources/solar-data/daylight-orientation-melbourne-city-centre-au.md) - [Solar Altitude & Azimuth: Melbourne City Centre, Australia](https://harth.build/resources/solar-data/solar-altitude-azimuth-melbourne-city-centre-au.md) - [Solar Shading Design: Melbourne City Centre, Australia](https://harth.build/resources/solar-data/solar-shading-design-melbourne-city-centre-au.md) - [Sun Path: Melbourne City Centre, Australia](https://harth.build/resources/solar-data/sun-path-melbourne-city-centre-au.md) ## Sources and method National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/AUS/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 AU dump](https://download.geonames.org/export/dump/AU.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 11523810).

No. 264.1 is the World Bank ICP 2021 national construction price-level index for Australia, with the world equal to 100. It is a cross-country screening statistic, not a Melbourne City Centre AUD/m² rate, escalation index, quote or tender estimate. ### How should a Melbourne City Centre house estimate replace this screening benchmark? Collect current Melbourne City Centre 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-melbourne-city-centre-au%2F - View this page in a browser: https://harth.build/resources/construction-costs/house-construction-cost-melbourne-city-centre-au/ - All resources for agents: https://harth.build/llms.txt
