For the last 10 years we have been sharing useful information to guide you on the costs for your construction project in Ireland.

Calculating the construction costs for your project is not an easy task. Every year we publish some guidelines and average prices to help you getting an approximate figure.

You can check our other articles in this series here.

The big news this year is the publication of the Building/Construction Cost Guidelines 2019 by the RIAI. This was long due an update and it provides a good overview of the current construction costs.

Construction in Ireland continues to boom, with all sectors showing significant growth.

Tender prices are still increasing in 2019, with construction inflation levels running well ahead of general inflation rates. This is fuelled by increased activity, pressure on wage rates, increases in material prices and regulatory changes.


Linesight’s reported that this year prices will be back to where they were at the peak of the boom.


Linesight’s research shows that, on average, tender prices rose by approximately 7.5% during 2018 while construction input costs rose on average by 3.5%. Due to high ongoing demand this level of increase is likely to continue for the foreseeable future.

During 2019 Linesight  predicts that tender prices will increase by 6.5% on average. Their report emphasises the importance of budgeting for future construction inflation when evaluating proposed construction projects.

The rate of increase is not the same around the country – construction prices in the Greater Dublin Area and other major urban centres are increasing at a faster rate than provincial locations.


Average Irish Construction Prices 2019

To provide clients with guidance on building costs, the RIAI (The Royal Institute of the Architects of Ireland) has compiled the Building/Construction Cost Guidelines 2019. The information contained in this document is for guidance only using average costs for the building types as set out, current at April 2019.

The tables below are a summary of the RIAI Cost Guidelines 2019. The Guidelines highlight a number of exclusions and conditions and the summary below should be read in conjunction with the full document. The document can be downloaded here.

Guide to Rebuilding Costs in Ireland

The Society of Chartered Surveyors Ireland (SCSI) provides a House Rebuilding Cost Calculator here. This calculator can be used as a guide to give you a minimum base cost for your construction project.

SCSI House Delivery Cost Calculator Tool

SCSI have developed a useful online calculator for developers to perform an analysis tailored to their own developments.

Private/individual users should use this calculator cautiously. Professional fees, for example, will be considerable higher for private developments than they are for developer built schemes where the level of repetition is often high.

SCSI highlights that the actual construction costs or hard costs made up less than half of the total costs. The online calculator allows users to adjust each elemental component of both the hard and soft costs for themselves.


Typical Exclusions

There are a number of other expenses that you should also consider when estimating your project. See some of the exclusions that may apply to your project here.

Architect’s fees will vary based on a number of factors ranging from size and complexity to level of the service required. These two articles provide some guidelines:

Additionally, you may also need to allow for:

  • Design Certifier Fees
  • Assigned Certifier fees
