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

Building a house in Leitrim in 2026 costs around €273,000–€294,000 for the construction of a typical 145 m² mid-range two-storey home, before fees and VAT. Leitrim sits at a 0.82 multiplier — 18% below the Dublin baseline — the lowest national pricing tier, and is distinctive within it for one reason: it is Ireland's least populated county. Low day rates, yes. But also the shortest tender lists and the thinnest contractor market of any county in the Republic. The result is not higher rates — it is longer lead times. Factor that into your programme, and Leitrim delivers its 18% saving as honestly as any county in Ireland. Add fees, VAT at 13.5%, and a 10% contingency, and the same build lands at roughly €407,000–€410,000 all-in on a serviced site.

If you are building in Leitrim, the most important planning insight is time: more of it, at every stage. More time to assemble a tender list, more time to wait for sub-trade responses, more time to secure a main contractor start date. Quality work gets done here — it just needs earlier procurement than a busier county would require. A free first estimate from BeforeYouBuild gives you the cost baseline to work from.

What drives Leitrim-specific costs

The contractor market is the defining characteristic of Leitrim costing. Not higher rates — the market prices honestly at 0.82 — but fewer contractors quoting on any given project. Carrick-on-Shannon in the south has the county's most active residential market, with Shannon riverfront development and some lifestyle migration from Dublin via the N4 giving the town a level of contractor activity that supports competitive tendering. The N4 also gives Carrick reasonable materials logistics from Dublin supply depots without a meaningful delivery surcharge.

North Leitrim — Manorhamilton, Drumshanbo, Kinlough — is a different environment. Local sub-trade availability here is genuinely sparse: specialist trades often need to be sourced from Sligo, Enniskillen or Longford, and the response rate on tender enquiries is slower than in more active county markets. This is not a quality problem — contractors who work in north Leitrim are experienced and capable — but it is a programme planning issue that needs to be reflected in your tender and procurement timeline. Allowing two to three extra weeks in the tender period for north Leitrim projects is practical experience rather than pessimism.

Ground conditions across the county are variable — drumlin terrain in the south, glacial deposits and lake margins further north — and site investigation is worthwhile. Lough Allen's surroundings and the Iron Mountains create scenic landscape sensitivity that affects some rural planning applications. Carrick-on-Shannon is the more planning-straightforward location within the county.

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

Leitrim regional multiplier applied to the national mid-range rate: 0.82 × €2,300 = **€1,886 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 × €1,886 per m²: **€273,470**.

The full mid-range band at Leitrim rates runs €1,722–€2,050 per m², giving a construction cost range of **€250,000–€297,000** 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 **€262,000–€284,000** within a consistently mid-range spec.

Fees, VAT and admin

On top of base construction, allow around 10% for architect fees — roughly €27,000 on a €273,000 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. Utility connections (ESB standard connection, Uisce Éireann water and wastewater) add roughly €9,000–€10,000; rural sites requiring a septic tank should allow a further €10,000–€12,000.

VAT at 13.5% typically adds €38,000–€44,000 on a Leitrim 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 Leitrim runs **€400,000–€415,000** on a serviced site, or **€415,000–€430,000** on a rural site requiring a septic tank and longer utility runs.

How Leitrim compares with neighbouring counties

| County | Multiplier | Per m² (mid-range) | 145 m² construction | |---|---|---|---| | Dublin | 1.00 | €2,300 | €334,000 | | Leitrim | 0.82 | €1,886 | €273,000 | | Sligo | 0.82 | €1,886 | €273,000 | | Roscommon | 0.82 | €1,886 | €273,000 |

Leitrim, Sligo and Roscommon are all at 0.82 — identical county-average construction costs. The difference between them is not in the rate but in the contractor market: Sligo town has the deepest professional supply chain of the three; Roscommon has the most straightforward logistics as a Midlands-bordering county; Leitrim has the thinnest contractor market but the most distinctive riverine landscape and a well-connected southern hub at Carrick. Dublin is €61,000 above Leitrim in base construction for a 145 m² build.
