The 6 Best Construction Companies in Ireland

If you have a construction project coming up, then you’ll need dozens of pairs of hands to make your dream project come to life.

And what more can you ask for when you have the best construction companies in Ireland to help you out? In this article, we’ll discuss them each in detail, as well as answer some common questions about them.

How much do construction companies charge in Ireland?

Budget plays a key role in every project. So before anything else, let’s discuss that first. 

In Ireland, construction costs will depend on several factors such as property size, location, finishes, design, materials, and more.

According to McAreavey Construction, building costs can range from €110 to €160 per sq. ft. with builder’s finish. A builder’s finish includes the main elements of a house including flooring, painting, kitchen, wardrobes, and more.

You’ll also have to allot around €15,000 for planning permission fees, engineer site inspections, signing off stage payments, solicitor fees, council development charges, utility connection charges, and many more. 

Location also plays an important role in the overall cost. You would be spending a lot more in a project based in Dublin compared to Waterford. 

According to the Irish Times, construction costs in Dublin are set at €2,400 per sq. m. 

For instance, a three-bedroom house in the Greater Dublin Area would average at around €371,000. For the same quality and house type, it would cost around €250,000 on average in areas outside of Dublin.

So really, there’s no one-size-fits-all construction cost. We recommend contacting your chosen construction company to get an exact quote for your project. 

The Best Construction Companies in Ireland

Here’s a glimpse of what we considered in our selection:

  • Industry experience, to make sure that they’re fully qualified to do the job
  • Sustainability, such as initiatives on energy efficiency, which ensures that they’re also doing their part in protecting the planet 
  • Specialisation, to make sure that they can meet your unique requirements
  • Client satisfaction, which speaks highly of the quality they provide

So let’s get right to it, here are the top construction companies that Ireland has to offer!

1. Flynn 

Flynn's Homepage
SERVICESCommercial, Retail Projects
ADDRESSFlynn House, Blackwater Road, Glasnevin, Dublin 11
CONTACT DETAILS01 850 3000 | [email protected]
OPERATING HOURSMon to Fri: 8:30 am – 6:30 pm

If you’re looking for a contractor who will take care of your commercial project from the ground up, then Flynn makes a fantastic choice. From pre-construction to fit-outs, rest assured that they’ll work with you through the entire project.

This award-winning construction company is responsible for the Terminal 1 departure hall of Dublin Airport, plus several retail shops around it. This includes Starbucks, McDonalds, WHSmith, Harvest Market, Slaney Bar, and Victoria’s Secret.

From this, you can easily tell that their expertise lies in airport infrastructure. Despite this specialisation, they have projects across different industries, from healthcare to hospitality.

But perhaps the biggest thing that impressed us was their commitment to sustainability. What this means is that they set annual targets to lessen carbon emissions.

One way they do this is by reviewing their energy sources in their business approach. This also applies to their businesses across the UK and Europe, since they operate abroad too. 

You don’t often come across a net zero contractor such as them, which is why we didn’t hesitate to give them a spot on our list!

The only major downside with Flynn is that they don’t really do residential projects. We noticed that they work best for major projects too, so don’t hesitate to skip this one if you’re not looking for those. 


  • Award-winning company
  • Specialises in airport infrastructure
  • Sustainable approach
  • Has branches in UK and Europe
  • Large team 


  • Not ideal for small-scale projects
  • Doesn’t cover residential projects

OPERATING HOURSContact for More Information

For those residing around Limerick (or planning to relocate there), this one’s for you! Whether you’re planning a new build or perhaps an extension, DL Construction specialises in residential construction from planning, right down to finishing touches. 

Now, this construction company may not be as big or as well-known compared to others, but there’s something about smaller businesses that’s very appealing too. 

From our experience, smaller companies give more personalised services, which also cuts a lot of red tape that’s often associated with large corporations. 

And we can see that DL Construction’s clients notice the same thing, based on the reputation they’ve built for themselves online and beyond. This is why we were glad to offer them a spot here!

Of course, smaller companies also have their fair share of drawbacks. For instance, their team is significantly smaller than many others, which could mean limited availability at times. 

We’ve also noticed that they mostly focus on residential work, not so much on commercial projects. But seeing that they’re a relatively new company (less than 5 years old), we can understand why they haven’t branched out yet.

They do work alongside architects and interior designers, so no project is completely closed off. In fact, they also cover projects around the Munster region, so you can say that their scope is pretty wide.

You can schedule a free consultation with them to see whether they make the right fit for you or not. 


  • Specialises in residential construction
  • Covers projects around Munster 
  • Caters to interior/exterior design consultations
  • Free consultation


  • Limited availability
  • Not suitable for commercial projects
  • Lacks information on sustainability

Customer Reviews

Quality of work was at the highest standard

“Would highly recommend DL Construction. They completed a substantial turnkey project in 2019 for us. From our initial meeting to project completion their professionalism and quality of work was at the highest standard. The project was delivered on time and within budget. Along with the construction they Project Managed the engineering and the final fitout (Tiling, Painting, Kitchen) and provided great guidance along the way. Their team are a pleasure to work with and we are truly delighted with the outcome.” —Adrian Broderick, Google Reviews

Team went the extra mile

“Just like to write a few words of praise for the professionalism & quality of work that DL Construction showed during the tender, quote, construction & completion of our extension. Throughout the project Diarmuid & Liam showed patience and understanding to our needs and truly listened and adapted to our requests as the build grew.. We were under time constraints (Aren’t we all!) with a newborn on the way but the team endeavoured to finish on time and leave the house in an immaculate condition once building had finished. It is a bit of a cliché to say the team went the extra mile but I can honestly say they did and as such, deserve the reputation they work hard to protect and exceed. I would have no hesitation in recommending the company and would be happy to answer any questions that a prospective customer may have.” —Dean Rice, Google Reviews

3. Mac-group

SERVICESConstruction, Interiors, Modular Construction
ADDRESSRockfield, 4th Floor South Block, Dundrum, Dublin
CONTACT DETAILS01 644 9650 | [email protected]
OPERATING HOURSMon to Fri: 9:00 am – 5:30 pm

Mac-group has been around since 2002. From being a one-man team, this business has become one of Ireland’s highest-grossing construction companies, trusted by many prominent brands like Intel, Microsoft, Mastercard, and more.

They’re an award-winning company with many years of experience under their belt, specialising in a broad range of construction projects. From single-storey construction to large-scale schemes including hotels and malls, this company covers all the bases.

For a company that large, we think it’s very important that they also do their part in minimising their environmental footprint. And we’re glad to see that it’s actually the case with them.

Their environmental management system is certified to ISO 14001:2015, and is updated regularly to reflect changes to UK, Irish and European legislation.

In short, they try to make buildings as green as possible, whether it’s through energy or water efficiency. So if this is something that resonates with you, then we highly recommend them for sustainable building projects.

This company even has their own interior design firm, which truly makes them a great choice for clients who wish to get construction and design services in one place.

Given their reputation, we should give you a heads up that they may be pricier compared to others, especially if you’re planning a simple one-storey house only. 


  • Award-winning company
  • Sustainable approach
  • Has offices abroad
  • Caters to interior design consultations
  • Large team


  • May be relatively more expensive
  • Mostly caters to commercial projects

Customer Reviews

Delivered the project on time and in a safe manner

“The key takeaway about with mac-interiors was their flexibility, approachability and their collaboration to share information and knowledge with the client. From inception to completion, their project staff conducted themselves very professionally, met key milestones on the schedule & delivered the project on time and in a safe manner. I especially commend their safety approach & their up-front escalation of safety observation throughout the duration of the project. The quality of their fit out is excellent and all specifications were met. The design team and our end users would happily recommend and would gladly avail of their services in the future. An excellent project for all concerned with a delighted customer.”– Danny Griffin, Intel

4. McAreavey Construction

SERVICESDesign and Planning, Residential Construction
ADDRESSScarteen Road, Newmarket, Co. Cork
CONTACT DETAILS086 805 2097 or 029 541 00 | [email protected]
OPERATING HOURSMon to Fri: 9:00 am – 5:00 pm

McAreavey Construction is another homegrown business that you should definitely consider, and here’s why!

This Cork-based construction company will walk you through the entire process, from concept planning to actual construction. If you don’t have your own design yet, they can also help you with that, thanks to their in-house architectural service.

Like most of our entries here, McAreavey Construction also plays a part in being sustainable as much as possible. This is why they specialise in new-build energy-efficient homes. 

And how do they do this? They increase insulation and improve air-tightness to reduce the use of fossil fuel-based heating systems. 

In fact, they actually build all new homes to a minimum Building Energy Rating (BER) A3, which sits among the gold standards when it comes to energy efficiency—and we’re really impressed by this!

We’ve heard many good things about them, like how responsive and approachable they are no matter how big or small your concern is.

But as we mentioned, small businesses may also have relatively limited manpower, which means availability can take a toll here. 

We’re also a bit bummed to learn that their focus is solely on houses. So, feel free to skip this one if you’re aiming to construct a commercial building. 


  • Specialises in energy efficient homes
  • All homes are built to reach BER A3 rating
  • Free consultation
  • Covers projects around Munster 


  • Limited availability
  • Doesn’t cover commercial projects

ADDRESSOffice 26, Calbro House, Tuam Road, Co. Galway
CONTACT DETAILS091 752 996 | [email protected]
OPERATING HOURSMon to Fri: 9:00 am – 5:00 pm

Kenny Developments Galway is a solid choice if you’re looking for an all-around construction firm that can do residential and commercial builds. They’ve been around since 1978 and have earned a reputation for developing luxury student accommodations—and for good reason.

After all, Galway is also home to NUI. So if you’re planning to venture into student housing, then we recommend consulting with Kenny Developments for that. 

There’s really no limitation when it comes to the construction projects they can build—detached houses, apartments, housing developments, business parks, and more. This impressive portfolio also extends to counties around Galway, which is another thing we like about them.

From what we’ve noticed, it seems that they mostly specialise in modern builds.

And like the majority of modern builds, it also means their work also strives to be energy-efficient as much as possible. So if this is something you’d prefer, then don’t hesitate to let them know about your requirements.

We just would’ve liked to see more information about this though. There’s also no confirmation whether they charge clients for initial consultations or not. 


  • Specialises in student accommodations
  • Specialises in modern builds
  • Covers Galway City and counties


  • No confirmation if consultations are free
  • Lacks information about sustainable initiatives
