Build Cost in Galway 2026 — Per m² Figures & Example Estimate

Building a house in Galway in 2026 costs around €287,000–€309,000 for the construction of a typical 145 m² mid-range two-storey home, before fees and VAT. Galway sits at a 0.86 multiplier — 14% below the Dublin baseline — placing it in the upper Connacht pricing band and reflecting a mature regional construction market that is genuinely competitive at tender stage. Add fees, VAT at 13.5%, and a 10% contingency, and the same build comes in at roughly €427,000–€430,000 all-in on a serviced site.

Galway is the most varied county in Connacht for costing purposes. The city and its commuter belt differ meaningfully from east Galway, and both differ from Connemara — which has its own logistics dynamic. The county multiplier represents a genuine average across those sub-markets. A free first estimate from BeforeYouBuild can show you where your specific site, location within the county, and spec lands within that range.

What drives Galway-specific costs

Galway city anchors a regional professional supply chain with more depth than any other county in Connacht. There is genuine competition at tender stage for a well-prepared project here — multiple main contractors, multiple sub-trades quoting independently — and that competition keeps rates honest. Commercial construction activity in the city and at IDA parks around Athenry and Tuam creates some demand pressure on mechanical and electrical trades, but nothing at the scale of Dublin or Cork city. East Galway — Loughrea, Ballinasloe, Tuam, Athenry — has straightforward logistics and a stable contractor market.

Connemara is a different calculation. Subcontractor day rates in Clifden, Roundstone and Lettermore are lower than in Galway city, but materials delivery from the city's supply depots adds meaningful cost on more remote sites — an extra €5,000–€10,000 on a typical build depending on distance and road access. On coastal Atlantic sites, exposure specification for windows, roofing membranes and external finishes also carries a modest premium above standard mid-range. Planning in Gaeltacht areas requires Irish-language submissions and the county council has particular design guidance around scale and form in sensitive landscapes.

Worked example: 145 m² mid-range 2-storey new build

Galway regional multiplier applied to the national mid-range rate: 0.86 × €2,300 = **€1,978 per m²** effective construction rate. Two-storey uplift of approximately 7.6% is reflected in the high end of the example range shown in the summary card above.

Construction cost

Base construction at 145 m² × €1,978 per m²: **€286,810**.

The full mid-range band at Galway rates runs €1,806–€2,150 per m², giving a construction cost range of **€262,000–€312,000** for a 145 m² build depending on specification. The ±4% band around the worked-example midpoint — reflecting finish level, insulation standard, heating system and window specification — runs approximately **€275,000–€298,000** within a consistently mid-range spec.

Fees, VAT and admin

On top of base construction, allow around 10% for architect fees — roughly €29,000 on a €287,000 build. Structural engineer and quantity surveyor fees typically run €8,000–€9,000 combined. Planning and regulatory administration — covering the planning application fee, Disability Access Certificate, BCMS Commencement Notice, Assigned Certifier fee, site survey, ground investigation, BER assessment, and site insurance — adds around €6,000–€7,000; Gaeltacht applications may require additional translation and Irish-language professional input. Utility connections (ESB standard connection, Uisce Éireann water and wastewater) add roughly €9,000–€10,000 on a standard site; rural sites requiring a septic tank should allow a further €10,000–€12,000.

VAT at 13.5% typically adds €40,000–€46,000 on a Galway mid-range build of this size. With a 10% contingency built in, a realistic all-in budget for a 145 m² mid-range two-storey in Galway runs **€420,000–€435,000** on a serviced site, or **€435,000–€450,000** on a rural site requiring a septic tank and longer utility runs.

How Galway compares with neighbouring counties

| County | Multiplier | Per m² (mid-range) | 145 m² construction | |---|---|---|---| | Dublin | 1.00 | €2,300 | €334,000 | | Galway | 0.86 | €1,978 | €287,000 | | Mayo | 0.82 | €1,886 | €273,000 | | Clare | 0.85 | €1,955 | €283,000 |

Galway at 14% below Dublin sits above both its immediate neighbours Mayo and Clare. The difference between Galway and Mayo (€14,000 in base construction) partly reflects Galway city's deeper contractor supply chain. Clare sits between the two at 0.85. For a 145 m² build, the spread across the three counties amounts to roughly €14,000 — meaningful but not dramatic, confirming that the broader West/Connacht regional band is fairly tight.
