Minister for Transport Darragh O’Brien has today (16 September 2026) received approval from Cabinet to move MetroLink to the detailed tender stage, where market bids will be sought and partners selected to build and operate MetroLink – National Transport.
The planned 19km metro will connect Swords in north Dublin with Charlemont on the south side, travelling through Dublin Airport and the city centre. It will include 16 new stations, 11 of them underground – and is intended to reduce pressure on the existing Luas and bus networks.

According to Independent.ie, the project has been more than 20 years in planning and has been beset by delay after delay. Earlier estimates had put the price tag at €12bn, with an upper estimate from transport officials of €20bn.
- It is also understood that The MetroLink rail line will help deliver around 77,000 homes along the route, and it is expected that €500m will also be put aside to build housing for 2000 to 8000 MetroLink workers – with a view to the State owning these houses once the project is complete.
Understandably, much of the public discussion has been focused on the cost of the project, its construction timetable and the improvements it could bring to Dublin’s transport system. But I also believe this much needed and enormous project also raises an important housing question:
Where will the thousands of people needed to build it actually live?
As I mentioned earlier, around 8,000 workers could be needed. And plans are now being considered to provide accommodation for between 1,500 and 2,000 workers, potentially creating housing that could eventually become a State asset once the projects are completed.
At the same time, MetroLink is ‘expected to support major housing development along its route’. I cannot fully verify what this statement entails at this time, but I believe that this creates an interesting relationship between MetroLink construction, labour and housing.
While Ireland needs workers to build this infrastructure, those workers need somewhere to live.

- International construction companies are expected to bring some workers into Ireland to supplement the existing workforce.
- Transport authorities have discussed accommodation for approximately 1,500 to 2,000 MetroLink workers with the Land Development Agency.
- One option under consideration could see the worker accommodation eventually revert to the State.
- The latest reported MetroLink cost range is approximately €14.5 billion to €17.5 billion.
- MetroLink is also expected to support significant future housing development along its transport corridor.
1. Why Does MetroLink Need So Many Workers?
MetroLink isn’t just another railway line. This project involves:
- underground stations,
- tunnelling & excavation,
- bridges,
- utilities,
- rail systems and major engineering works across Dublin.
Ireland does not currently have enough companies with the specialist experience and scale required to lead every part of a project of this size. As a result, major international construction companies are expected to participate.
2. Housing Up to 2,000 MetroLink Workers
Transport authorities have reportedly been in discussions with the Land Development Agency (LDA) about providing housing for approximately 1,500 to 2,000 people.
This will be a real challenge because Dublin already has a very difficult rental and housing situation. So it is no surprise that bringing large numbers of additional workers into the city without increasing accommodation could create further demand for existing rental properties, and more pressure on infrastructure i,e traffic, emergency services etc,.
- The hope is that purpose-built worker accommodation could reduce some of that pressure. Instead of thousands of incoming workers competing with existing residents for apartments and houses, some could have accommodation specifically provided as part of the MetroLink project.
3. Purpose-Built Accommodation Could Eventually Become State Housing?
The Irish Times reports that discussions include the possibility that the accommodation could be transferred to the State once MetroLink construction is completed. However, the arrangements have not yet been finalised.
The basic idea has been discussed before.
Last year, Trinity College Dublin transport professor, Brian Caulfield, previously suggested an “Olympic village” style approach to MetroLink accommodation: build somewhere for project workers to live and then return that accommodation to the State when the project ends. Irish Times
If designed correctly, accommodation initially required for construction workers could potentially have another use afterwards.
- Now, exactly what that use would be still remains unclear.
- It might become housing, student accommodation or another form of residential accommodation.
The important point is that money spent housing temporary workers could potentially create a long-term physical asset; instead of simply paying for temporary hotel rooms or placing additional demand on Dublin’s existing rental stock.
4. The €500 Million Figure Probably Needs More Context
Various online reports have mentioned €500 million in connection with worker accommodation.
Now, it would be easy to divide €500 million by 2,000 workers and conclude that each place would cost approximately €250,000, but I beleive that would be misleading.
The Irish Times reports that just over €500 million in the revised estimates covers worker accommodation and other commitments made during the planning process that were not included in earlier designs.
- We therefore do not yet know how much of that money would actually be spent building accommodation.
- We also do not yet know the final number, design, location or long-term use of the units.
But if we are to follow the usual pattern of final costing for projects that take years to complete, it is very likely that these costs will be higher by the time they are realised.
5. Could MetroLink Compete With Housing for Available Workers?
If there is one major thing Ireland has been dealing with since this housing crisis began, it is the shortage of skilled labour. This has also been a topic of discussion across many publications for years now.
- The amount of housing required to slow down the housing crisis requires thousands of engineers, electricians, plumbers, machine operators, construction managers, surveyors, concrete workers and other skilled trades.
- These are the mostly the same skills that the Metrolink projects will require.
- Let’s not forget; water infrastructire, roads, schools, hospitals etc as well
What this means is that Ireland’s construction challenge isn’t just about finding enough money, it is also about having enough people and productive capacity to deliver everything that is being planned.
6. Could MetroLink Also Expand Ireland’s Construction Workforce?
Kindly allow me to play devil’s advocate for a minute.
MetroLink doesn’t necessarily have to take thousands of workers away from housebuilding, as large international companies are expected to bring specialist personnel into Ireland.
Some of those workers may leave again when the project finishes, while others may stay.
It can be argued that Irish workers could also gain experience from working on one of the largest infrastructure projects ever undertaken in the State, and that MetroLink could therefore place additional pressure on Ireland’s construction workforce while also attracting new workers and expertise.
7. MetroLink Could Also Help Unlock 77,000 more homes
Government reporting around MetroLink has suggested that the project could help enable approximately 77,000 homes along the wider route and surrounding areas.
This does not mean MetroLink itself will build 77,000 houses. It only means that improved transport and infrastructure could help support land and developments where large amounts of housing are planned.
Let’s establish some standard truths:
- Good transport infrastructure definitely makes it easier to build more houses.
- And people living close to high-capacity public transport can travel to work, education and other services without every additional household creating more road traffic.
This is a major reason why huge transport projects are often closely linked with housing development.
Transport infrastructure can enable housing development, but developers, local authorities, Approved Housing Bodies and other organisations would still have to deliver the homes.
Summary
| What we know | What we don’t Know |
|---|---|
| Around 8,000 workers required | How many will come from overseas |
| Housing for 1,500–2,000 workers being considered | Where it will be built |
| Discussions have taken place with the LDA | The final design and cost |
| Accommodation could eventually be transferred to the State | What it would be used for afterwards |
| MetroLink could support major housing development | How many potential homes will actually be delivered |
MetroLink is primarily a transport project, but its sheer scale means that many other social and economic aspects will be greatly affected. The proposal to provide accommodation for up to 2,000 workers shows that major infrastructure projects such as Metrolink, cannot be separated completely from Ireland’s housing shortage.
And without additional accommodation, incoming construction workers could place a ton of extra pressure on Dublin’s existing rental market.
- Purpose-built accommodation could provide another option, provided those buildings can later become useful State-owned residential assets. If that is indeed the case, then the long-term value could extend beyond MetroLink itself.
But let us not forget, Ireland wants to build more homes while simultaneously delivering one of its largest ever infrastructure projects in its history.
The real challenge will be to make sure that Ireland can build the infrastructure needed for new homes without reducing its ability to build the homes themselves.
