A full house renovation in Ireland usually costs between €1,500 and €2,500 per square metre for a standard, good-quality finish, and €2,500 to €4,000+ per square metre once you strip the house back and renew the structure and services. For a typical three-bed semi, that puts most full renovations in the €165,000 to €250,000 range.
Those bands cover the vast majority of projects, but the real house renovation cost in Ireland always comes down to your specific property. Scope, spec, the age and condition of the house, and how much you change the layout all swing the final figure, often by a factor of three or four on the same square footage.
Owners who design first and price second usually get a nasty surprise at tender stage. The safer order is to fix a realistic budget for your house first, then work the design to it.
How Much Does a Full House Renovation Cost in Ireland?
A full house renovation runs €1,500 to €2,500 per square metre for a standard finish and €2,500 to €4,000+ per square metre for a high-spec or structural rebuild. On a typical 100 m² home, a standard renovation works out at roughly €150,000 to €250,000, before professional fees, VAT and contingency.
| Renovation level | Cost per square metre | What it usually covers |
| Light refresh | €1,000 to €1,500 | Painting, flooring, light fittings and minor joinery, with no structural or services work |
| Standard full renovation | €1,500 to €2,500 | New kitchen and bathrooms, partial rewire and replumb, insulation and some layout changes |
| High-spec or gut renovation | €2,500 to €4,000+ | Strip back to structure, new services throughout, structural openings and higher-end finishes |
Construction costs have kept rising, and the Society of Chartered Surveyors Ireland reported national rebuild costs up around 7% in the year to late 2025, which feeds straight into renovation quotes. That is why a figure from two years ago will usually undercount today’s job.
What Drives House Renovation Costs Up or Down?
The single biggest driver is scope, meaning how far you strip the house back, followed by spec, structural work and the condition of the existing building. Two identical semis on the same road can differ by €150,000 depending on these choices, so the per square metre band only becomes a real number once the scope is set.
The main things that move the figure:
- Scope. A cosmetic refresh sits at the bottom of the range. A whole-house renovation that renews layout and services sits near the top.
- Structural work. Removing walls, forming openings and adding steel needs an engineer’s input and pushes the rate up fast.
- Services. A full rewire and replumb in an older house is a large, unavoidable line item that a per square metre estimate often hides.
- Condition and age. Older Dublin homes throw up damp, dated wiring and poor insulation once the walls are open, and these are rarely visible before work starts.
- Finishes. The gap between standard and premium kitchens, tiles and flooring alone can add tens of thousands across a full house.
How Much Does It Cost to Renovate a 3-Bed Semi in Ireland?
A full renovation of a typical three-bed semi costs €165,000 to €250,000, based on roughly 90 to 110 m² at standard to good spec. A lighter refresh comes in under that. A full gut with structural changes and premium finishes pushes above it.
That budget usually stretches to a new kitchen and bathrooms, a rewire and replumb, insulation upgrades, new windows and doors, and some reconfiguring of the layout. Where the number climbs is structural openings, a two-storey reconfiguration, or bringing the whole house up to a high energy rating.
House Renovation Costs in Dublin vs the Rest of Ireland
Renovation in Dublin sits at the top of the national range, commonly €2,000 to €2,500 per square metre and up for a standard full renovation, because labour, site access and demand all run higher in the city. The same job in a commuter county or a rural area can be 10 to 15% cheaper for like-for-like work.
For homeowners in the Dublin commuter belt, that regional gap is worth knowing but rarely decisive. Access, parking and the age of the housing stock matter more to the final quote than the county line does. An older terraced house in the city can cost more to renovate than a newer semi further out.
Why Renovation Quotes Come Back Over Budget
Renovation quotes blow the budget most often because the house is designed first and priced second.
A design-and-build route, where one team costs, designs and builds under a single contract, closes that gap because the budget is agreed before any drawings begin.
The usual reasons a renovation runs over:
- Designing before costing, so the brief was never affordable
- No contingency for the unknowns behind old walls
- Scope creep once work is underway
- VAT and professional fees left out of the headline figure
How to Set a Realistic House Renovation Budget Before You Start
Set your renovation budget before you commission any design, not after, by getting a real cost range for your specific house and working the drawings to that figure.
- Get a real cost range first. A feasibility-style assessment of the house, site and brief gives you a figure to design against, rather than a guess.
- Add a contingency. Set aside 10 to 15% for the surprises an older house tends to hide, so one bad discovery does not derail the job.
- Count VAT and fees in. Renovation labour carries the reduced 13.5% VAT rate, and a separate architect and engineer typically add another 10 to 15% on top of the build cost.
- Factor in grants. If your renovation includes insulation, a heat pump or new windows, SEAI home energy grants can offset part of the energy-upgrade cost and lower your net spend.
- Confirm the number on site. Only a written cost from a builder who has walked your house reflects its real condition.
Book a feasibility consultation to get a realistic cost range for your renovation before the design stage begins.
