Renovation calculator · Dublin · 2026
Renovation cost calculator for Dublin.
Dublin renovation costs sit materially above the SCSI national mean for three structural reasons: labour day-rates (Dublin electrician and plumber rates roughly 20% above the SCSI national mean), site logistics (skip permits, parking suspensions, restricted access in the inner city and South County postcodes) and planning friction (dense Conservation Area coverage across Georgian/Victorian neighbourhoods plus Article 28 protected-structure restrictions on many older terraces). A typical Inner Dublin structural renovation of a 3-bed terrace runs €265,000–€335,000 inc-VAT including a 10% contingency. South County postcodes (D4, D6, D14, D18) sit at the upper end of that range; North City postcodes (D7, D9, D11) at the lower end.

Most South Dublin areas (Dún Laoghaire-Rathdown, parts of Dublin City Council) operate strict Architectural Conservation Areas (ACAs) under the Planning and Development Act 2000. ACAs withdraw most exempted development rights and require Section 5 declarations for many works that would be straightforward in suburban Dublin. The practical effect: even routine rear extensions and dormers need a full planning application in many South Dublin neighbourhoods. Add €34 (Form D fee) plus €1,800–€4,500 for architect drawings, €2,500–€6,500 for the BCAR Assigned Certifier/Design Certifier, and 8–12 weeks for the planning decision. Pyrite is a residual risk for properties built 1997–2013 in north Dublin (D11, D13, D15, D17), Fingal and adjoining parts of Meath — a pyrite assessment runs €600–€1,200 and is worth ordering before any structural commitment.
