The math behind our cost of building a house in ireland calculator relies on the Society of Chartered Surveyors Ireland (SCSI) methodologies, adjusted for current inflation. We break the calculation into four primary phases:
- Shell and Core: This is the base cost per square meter multiplied by the regional factor.
- Site Development: Fixed costs for utilities, drainage, and ground conditions.
- Professional Overheads: A percentage-based addition for intellectual services.
- Risk Management: A 10% contingency buffer—crucial for Irish builds where ground conditions or weather can delay work.

| Region (R) | Locality multiplier | Index | 1.0 – 1.2 |
| Fees (F) | Professional services | % | 10% – 15% |
