Construction Information Services (CIS) (CIS) reports Ireland's construction market will hit over €20.4bn by 2027, driven by civil engineering and commercial projects, with significant growth predicted in 2027 (+28%) after a dip in 2026, despite challenges like housing sector growth slowing, notes The Irish Independent and O'Neill & Brennan, highlighting overall strength despite sector variations. 

Key Takeaways from the CIS Report 
  • Overall Market Value: Expected to exceed €20.4 billion by 2027.
  • Growth Drivers: Civil engineering and commercial sectors are leading the expansion.
  • Year-on-Year Trends: Strong finish to 2025 (+19%), a dip in 2026 (-9%), followed by robust growth in 2027 (+28%).
  • Housing Sector: Residential growth is slower, with only 5% cumulative growth predicted between 2026-2027, despite high demand, reports O'Neill & Brennan. 
In essence, while the housing sector faces unique pressures, the broader Irish construction market is forecast for substantial growth, culminating in a significant boom by 2027, according to Construction Information Services (CIS).
