How much does a garden room cost in Ireland?
In PlotNua’s research, published prices for installed, finished garden rooms ran from €9,799 to €43,650.
That range comes from 22 products sold by 7 suppliers, in PlotNua’s research snapshot of 7 October 2026. It is the spread of prices those suppliers advertise, not a typical Irish price and not an all-in quotation: foundations, electrical connection and VAT can still sit outside it.
Some specialised garden buildings in PlotNua’s research are advertised at substantially higher prices. These are not included in the comparison above because their pricing and installation arrangements differ.
So treat it as a guide to what is advertised, then use the checklist further down to turn any price into one you can actually compare.
Garden room and garden office prices by what the price covers
The same building can be sold three different ways: as a kit you assemble, delivered and built for you, or finished turnkey. Each is a different purchase, so prices are grouped by what the supplier says the price includes, and never mixed. Garden offices sit in the same groups: a garden office is a garden room bought for work, and is priced the same way.
| What the price covers | Published range | Based on | Price says VAT is included |
|---|---|---|---|
| Installed and finished (turnkey)The supplier's price includes building it on your site and finishing it. | €9,799 – €43,650 | 22 products 7 suppliers |
2 of 22 |
| Kit, or installation unclearThe supplier sells it as a kit or installed, and the price does not say which. | €3,624 – €23,990 | 65 products 6 suppliers |
21 of 65 |
| What the price covers is not statedThe price is published, but nothing says what it includes. | €4,713 – €43,450 | 111 products 6 suppliers |
106 of 111 |
No range is shown where fewer than 3 suppliers publish prices on the same basis, because a range from one or two companies is really their price list. That applies to:
- Supply only, installation extra: 5 products from two suppliers
- Installed, but foundations excluded: 10 products from two suppliers
- Supplied and erected: 8 products from one supplier
- Sold through a dealer, basis unknown: 1 product from one supplier
Why PlotNua does not publish an average garden room price
An average only means something when every price covers the same thing. These do not. A kit you assemble yourself, a room built and finished on your site, and a price that does not say what it includes would all count equally, so the result would describe the mix of products in the research rather than what you would pay.
So this guide shows the range for each kind of price, how many products and suppliers sit behind it, and how many say VAT is included. The same applies to garden offices: they are priced the same way as garden rooms, and what you pay depends on what is included, not on what the room is called.
Why advertised garden room prices are hard to compare
Before you can tell whether one garden room is dearer than another, you have to know what each price covers. Most of the time, that is not published.
177of 247 published prices do not establish what the price includes
94of 247 do not say whether VAT is in the price
45of 247 publish a floor area
PlotNua’s research snapshot of 7 October 2026: every priced garden room in the research, 247 in all.
Price per square metre does not solve it. Rooms priced on different bases, or with a different finish inside, can be several times apart per square metre, so a figure like that says more about what was left out than about value.
What can sit outside the advertised price
These are the costs that most often separate an advertised price from a final quotation. Whether each one applies depends on the supplier and on your garden.
- VATMany published prices do not say whether VAT is included. On a building of this kind that can be a large part of the bill, so confirm it in writing.
- Foundations and groundworkA garden room needs a level, load-bearing base. Some suppliers build it, some price it separately, and some leave it to you. Sloping or soft ground, access for machinery and removing soil can all add to the work.
- DeliverySome prices include delivery nationwide, some only within a region, and some charge by distance. Tight side access can also mean extra handling.
- InstallationA kit price leaves the building to you or to a builder you hire. A “supplied and erected” price may still stop short of the interior finish.
- Electrical connectionA room can come wired inside but not connected to your house. The cable run from your consumer unit, and the certificate for that work, are often quoted separately.
- Building Regulations and planningAbove 25 m² a garden building must meet the Building Regulations in full, and the planning exemption has its own size and position limits. Both can change the specification you pay for. Living in the Garden explains the rules.
A garden room quote checklist
Ask every supplier the same questions, in writing, before you compare their prices.
- Is VAT included in this price?
- Is the base or foundation included? If not, what does it need, and who builds it?
- Is delivery to my address included, and is my side access suitable?
- Is the building put up by your own team, or is this a kit?
- What is finished inside: insulation, lining, flooring, sockets, lighting, heating?
- Is the electrical connection to the house included, with its certificate?
- What is the floor area, measured inside and outside?
- Does this design stay within the planning exemption for my garden, and does it need to meet the Building Regulations?
- What warranty applies, and to which parts?
- Is this a “from” price? If so, what does the version I want cost?
If two suppliers give different answers to the first four questions, their prices were never comparable in the first place.
Garden homes are a separate price question
A garden home, a detached building someone can live in, has a different set of rules since July 2026: its own size range, conditions and notices, and the Building Regulations in full. Very few are advertised with a price yet, so this guide does not put a figure on one.
Living in the Garden explains what changed in 2026 and how the garden room and garden home rules differ.

How these figures were made
These figures come from PlotNua’s research snapshot of 7 October 2026: 573 garden room products in the Atlas, of which 247 carry a euro price PlotNua can stand behind, from 24 suppliers, with a published route to Irish customers.
Every price inside a range above was last checked against the supplier’s own published information between 8 August 2026 and 6 October 2026. Ranges are shown only where at least 3 suppliers price on the same basis, and prices on different bases are never combined.
25 further prices in these groups have no recorded check date, so they are left out of the ranges until they are rechecked.
This is not a census of the Irish garden room market. It describes what PlotNua’s research holds, and a supplier that publishes no price cannot appear in it. Suppliers are not named or ranked here, and PlotNua has no commercial arrangement with any of them.
