The Cork office market recorded a 19.4% increase in take-up during the first half of this year.
Savills Ireland said transactions involving 196,400 sq ft of space were recorded.
The growth was driven in large part by the public sector which took 56% of the space, it said.
The HSE was a key player in the market, taking 64,000 sq ft of space at Westfield Office Quarter in Ballincollig.
It also bought 35,200 sq ft at Building 4, University Technology Centre.
In total the HSE's expansions made up 56% of the first half deals.
Overall, there were 27 deals completed, up from 19 in the first half of last year.
Rents remained stable at around €32.50 per square foot, although the vacancy rate stood at 13.7%, down slightly from 14.3% in the same period last year.
"The resilience of Cork's office market is truly commendable, especially given the global challenges we've faced in recent years," said Sheila Madden from Savills.
"The current trends, emphasizing health, wellbeing, and sustainability, underline the evolving priorities of tenants."
"The dominance of the public sector, combined with the emphasis on energy efficiency and sustainability, showcase the maturity and future-readiness of the market. The consistent take-up, rental stability, and anticipated growth paint a positive picture for Cork as a competitive office hub."
Savills said the pipeline is promising, with 128,000 sq ft of space expected to be completed at Horgan’s Quay 2 by year end.
A further 3.1 million sq ft is proposed in other projects.
