The PLI is not a city cost/m² rate, current escalation series or tender estimate.
Direct answer
For early house construction cost planning in Ennis, the World Bank ICP reports a 2021 Ireland construction price-level index of 152.8, with the world equal to 100. This is a national comparison—not a Ennis EUR/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Ireland in 2021; it does not measure a Ennis market basket or current house tenders. GeoNames 2964405 records the locality at 52.8436, -8.9864, with snapshot population 27,923. That ranks Ennis 14 of 50 listed places, while Limerick is the nearest listed peer at about 32 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.

|---|---|---|
| National context | ICP 2021 PLI 152.8 | Retain only as dated cross-country context |

Price-level normalization worksheet
For a validated reference rate R from a country with construction PLI P, the transparent screening calculation is R × (152.8 ÷ P). At P = 100 the dimensionless ratio is 1.528; 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 | 152.8 (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 Ennis adjustment | Not asserted | Replace with current local comparable evidence |
| Result status | Screening normalization | Not a budget, quote or tender estimate |
