How Much Does It Cost to Renovate a House in Ireland? (2026 Room-by-Room Guide)

Last updated: 2 July 2026 · By Mossy Tariq, Founder — Property Blueprint Co.

Ask what it costs to renovate a house in Ireland in 2026 and the first answer is a range wide enough to be useless — somewhere between €20,000 and €200,000-plus. The range isn't wrong. It's measuring the wrong thing. A whole-house renovation is not one project with one price. It's four or five separate room-sized projects, each priced by a different set of trades, wearing a single quote.

A whole-house renovation cost is not one number. It's four or five room-sized numbers, and no builder quotes them separately unless you ask.

That's the gap this article closes: the room-by-room breakdown Irish renovation specialists actually report for 2026 — kitchen, bathroom, utility room, and garden — and why treating a house renovation as one number instead of four is the most expensive mistake in the budgeting phase of The 12-Phase System.

A house renovation quote is never one price.
It's every room's price, added together, and never broken down.

What follows is the room-by-room data, the mechanism that makes whole-house quotes hard to compare like-for-like, and the sequencing decision — room by room, or all at once — that changes both the cost and the disruption.

How much does it cost to renovate a house in Ireland in 2026

There is no single reliable figure for "the average Irish house renovation," and that absence is itself informative. The Central Statistics Office (CSO) tracks construction and renovation activity at a national level and shows spending trending upward through 2025 into 2026, while the Society of Chartered Surveyors Ireland (SCSI) publishes refurbishment cost guidance used across the industry — but neither produces one blended "average renovation" number, because a single figure would have to average a utility-room refresh against a full structural rebuild, and the result would describe neither.

Instead, summing the typical mid-range renovation for each of the four rooms most Irish homeowners actually touch — kitchen, bathroom, utility room, and garden — lands the combined figure somewhere between roughly €33,000 and €67,000. That is a genuinely useful planning range, because it is built from room-specific data rather than a national blend. Full-scope work that adds structural changes, a premium specification across every room, or an extension pushes well past €150,000, which is a different project entirely from a mid-range multi-room refresh.

Industry cost guides commonly quote a per-square-metre range, and that figure is almost never useful alone, because a euro-per-square-metre rate means something completely different in a kitchen — dense with cabinetry, worktop, appliances, and plumbing in a small footprint — than in a garden, where the same square metre carries a fraction of the trade density.

The SCSI's Real Cost of Renovation report makes the same point from the other direction, costing renovation property by property across individual case studies rather than publishing one national rate. That's why a room-by-room number serves almost every homeowner better than a whole-house aggregate: most Irish renovation projects touch one, two, or three rooms — not all of them.

What does each room actually cost

Here is the 2026 room-by-room breakdown, each figure sourced from Irish renovation specialists and each one covered in more depth in its own dedicated guide:

1. Kitchen — €5,000 to €50,000, mid-range €10,000 to €25,000. A budget or basic refresh runs €5,000 to €10,000, a mid-range renovation €10,000 to €25,000, and a high-end project €25,000 to €50,000, with layout ambition — not finish quality — the biggest single driver of where a project lands inside that span. See the full kitchen renovation cost breakdown for what sits inside each price tier.
2. Bathroom — €2,000 to €40,000-plus, national average around €12,000. A budget or small makeover runs €2,000 to €4,000, a mid-range renovation €10,000 to €18,000, and a premium fit-out €20,000 to €40,000 and beyond. Whether the plumbing moves is the single largest swing in any bathroom quote. The full bathroom renovation cost guide breaks down what separates a refresh from a full renovation, and the small bathroom renovation cost guide covers why a compact room or ensuite is never proportionally cheap.
3. Utility room — €2,500 to €18,000-plus. A basic fit-out onto existing plumbing runs €2,500 to €5,000, mid-range €5,000 to €10,000, and a bespoke fit-out with a relocated layout €10,000 to €18,000 and beyond. Moving a sink or washing machine connection is typically the cost that dwarfs everything else in the room. See the utility room cost guide for the full breakdown.
4. Garden — no single figure, because it isn't a single scope. A planting-and-turf refresh of a small plot lands at €3,000 to €6,000, a full transformation of a standard suburban garden runs €8,000 to €14,000, and full hard landscaping with patios, retaining walls, and decking pushes past €25,000 before a garden room or a glazed sunroom is even discussed. The garden renovation cost guide breaks apart what each layer actually costs, and the sunroom cost guide for Ireland covers the conservatory, warm-roof sunroom and orangery bands separately — the same problem this article solves at the whole-house level.
5. Whole house — the sum of whichever rooms you're actually touching, not a single aggregate. A homeowner renovating a kitchen and bathroom together is not running a single "average renovation" — they're running two room-specific projects that happen to share a start date, each priced against its own room's data above.

Notice the pattern: every room-specific figure above is tighter and more useful than the whole-house range in Section 1. That's the entire argument of this article.

Why does a whole-house quote hide the real room-by-room breakdown

Because a whole-house quote is built to be signed once, not compared four times. When a builder prices a whole-house job, the provisional sums and prime-cost items for each room get bundled into a single project total rather than itemised room by room. That bundling is not necessarily dishonest — it's how the quoting software and the trade's own cash-flow planning work — but it has a specific consequence for the homeowner: a "cheap" kitchen line inside the quote can be quietly subsidised by an inflated bathroom line, and there's no way to see it without asking for the breakdown in writing. Reading each builder's quote line by line — quote versus estimate, VAT, provisional sums — is covered in how to read a renovation quote.

This is the same mechanism the early phases of The 12-Phase System are built to catch at the single-room level — provisional sums, prime cost items, and exclusions that look like inclusions until the variation invoice arrives. At the whole-house scale, the same mechanism operates across rooms instead of within one, which is why two whole-house quotes for the same scope of work can land tens of thousands of euro apart with neither builder doing anything wrong on paper.

There's a second reason whole-house quotes resist comparison: mobilisation cost. A trade's cost of getting a crew onto a site is largely fixed whether they're doing one room or four, so adding a room spreads that cost thinner — genuinely cheaper per room, but it also adds a coordination layer a single-room job never has to solve. A whole-house quote blends both effects into one number, so the homeowner never sees which part of the "discount" is real efficiency and which part is corners cut on sequencing.

Should you renovate room by room, or all at once

Both are legitimate strategies, and the right answer depends on whether you're living in the house during the work — not on which one is "cheaper" in the abstract.

Renovating room by room, while living in the house, spreads the cost over time and lets each room's budget breathe without competing for the same trade slots. The tradeoff: a second site mobilisation when the next room starts, and disruption lived through twice — or three or four times — rather than once. For most Irish homeowners renovating one or two rooms rather than gutting the whole house, this is the default approach, and it's what the room-by-room figures in Section 2 are built around.

Renovating everything at once, typically while not living in the house, compresses disruption into a single period and lets trades move through the property in the most efficient sequence rather than working around a family still using the kitchen every evening. It also concentrates the risk — every room's budget is exposed to the same timeline, so a delay or a variation in one room can cascade into every other room's schedule. The cost per room can look identical on paper between the two approaches while the actual risk profile is not.

Neither approach is more "correct." The decision is about which risk you'd rather carry: extended disruption across a longer timeline, or concentrated financial and scheduling risk across a shorter one.

What separates a €40,000 renovation from a €150,000 one

Almost never the number of rooms alone. It's the combination of which rooms, what tier within each room, and how much structural work sits underneath the visible finish.

A €40,000 renovation is typically a kitchen and a bathroom at the mid-range tier from Section 2, with no structural changes — walls stay put, plumbing and electrical are updated in place, and the work is cosmetic-to-mid-range. A renovation running €150,000 and beyond is rarely "the same rooms, nicer finishes" — it's a different scope: structural wall removal, plumbing or electrical relocated rather than refreshed, kitchen and bathroom both at premium tier, plus utility room and garden scope layered on top, often with the notification and compliance costs that come with genuinely changing a home's structure. Which of those structural changes actually needs a planning application, and which fall inside the exemptions, is set out in the guide to planning permission for a renovation in Ireland.

This is why a single national average is close to meaningless for budgeting. It would have to blend a utility-room refresh with a structural rebuild. Your renovation is neither of those in the abstract — it's a specific combination of rooms and tiers, and the only accurate way to price it is against each room's own data, not a national blend.

How do you get an accurate number before you call a single trade

Price each room you're actually touching against its own data — not against a whole-house average, and not against a single €/m² figure that doesn't distinguish a kitchen from a garden. Use the room-specific ranges in Section 2 as the starting benchmark, then adjust for your specific tier: cosmetic, mid-range, or premium, per room.

The fastest way to do this without waiting on a builder's calendar is the free Irish Renovation Cost Calculator — it produces a trade-by-trade estimate for the specific rooms and tier you select, in under 5 minutes, and because it's run per room, it gives you exactly the breakdown a bundled whole-house quote won't hand over voluntarily. Run it once per room you're planning, and you have a room-by-room benchmark to hold every builder's whole-house quote against — the same discipline Section 3 describes trades relying on you not having.

That benchmark is also the input every later decision in The 12-Phase System is measured against — the brief, the budget, and the quote comparison all inherit whatever number you walk in with. Getting it right at the start, room by room, is cheaper than correcting it later.

Frequently asked questions

How much does it cost to renovate a house in Ireland in 2026?

There is no single accurate answer, and that's the point of this guide. Summing typical mid-range renovations across the four rooms most homeowners touch — kitchen, bathroom, utility room, and garden — lands the combined figure between roughly €33,000 and €67,000. Full-scope work with structural changes, a premium tier across every room, or an extension pushes the figure toward €150,000 and beyond. The only accurate number is the sum of the specific rooms you're renovating, priced individually.

Why do whole-house renovation quotes vary so much between builders?

Because whole-house quotes bundle each room's provisional sums and prime-cost items into one project total rather than itemising them room by room. That makes two quotes for the same scope of work difficult to compare like-for-like — a lower total in one quote can be hiding a more inflated line in one room, offset by a leaner line in another, with no way to see it unless the quote is broken down room by room in writing.

Is it cheaper to renovate a whole house at once or room by room?

Neither is definitively cheaper — the two approaches trade different kinds of risk. Renovating room by room spreads cost and disruption over a longer timeline but incurs a separate site mobilisation cost each time a new room starts. Renovating everything at once concentrates the mobilisation saving but also concentrates financial and scheduling risk, since every room's budget is exposed to the same project timeline. The right choice depends on whether you're living in the house during the work, not on which option has the lower headline price.

What is the average cost to renovate a kitchen, bathroom, utility room, and garden in Ireland?

Per Irish renovation specialists for 2026: a kitchen typically runs €5,000 to €50,000 with a mid-range band of €10,000 to €25,000; a bathroom runs €2,000 to €40,000-plus with a national average around €12,000; a utility room runs €2,500 to €18,000-plus depending on whether plumbing is relocated; and a garden runs €3,000 for a planting refresh up to €25,000-plus for full hard landscaping, typically the widest-ranging of the four.

Why is a per-square-metre renovation cost figure misleading?

Because trade and fixture density varies enormously by room type. A euro-per-square-metre rate for a kitchen — dense with cabinetry, worktop, appliances, plumbing, and electrical in a small footprint — means something entirely different from the same rate applied to a garden or a hallway. Two renovations quoted at an identical €/m² rate can differ by tens of thousands of euro once the actual room mix is accounted for, which is why room-specific figures are more useful than a blended per-square-metre average.

How do I get an accurate renovation cost estimate before speaking to a builder?

Price each room you're planning to renovate against its own room-specific data rather than a whole-house average. The free Irish Renovation Cost Calculator produces a trade-by-trade estimate for a specific room and tier in under 5 minutes, without needing a builder's quote first — run it once per room, and the combined result is a room-by-room benchmark you can hold any whole-house quote against.
