Sisk invests in Cork roots and future talent through new Mahon office 

Ireland’s largest building contractor, which had been located on the Kinsale Rd since 1967, has moved to a new office at City Gate, Mahon.

The new Cork office was officially opened this week by Michael McGrath, EU Commissioner, Gary McGann, chairman, Sicon Ltd (Sisk Group), and Paul Brown, CEO, Sisk.

The new office was retrofitted over a four-month period and has capacity for over 50 staff.

The company has recently been announced as main contractor for the extension of Center Parcs in Longford Forest, having completed the Dunkettle Interchange upgrade scheme and a Pfizer project in Ringaskiddy over the past 18 months.

In June 2024, Sisk moved over 250 of its staff into its new Irish HQ in Citywest, Dublin.

Roots

Paul Brown, Sisk CEO, said the company’s roots are firmly in Cork and the move to Mahon is an investment in its people and a vote of confidence for the wider Munster region.

“This move will enable us to support and attract future local talent into the construction sector. Our new office also complements our new HQ retrofit in Dublin,” he added.

“Additionally, it is a wider commitment by us to be best prepared to support the Government’s recent update to the national development plan — a bold vision that ramps up public capital investment to a historic €275.4bn from 2026 to 2035.

“Off the back of our successful completion of Dunkettle Interchange, we are positioned to support one of the most ambitious infrastructure programmes in our nation’s history — and one that we support and are ready to engage upon.”

Employs

Commissioner Michael McGrath said construction employs millions across Europe.

“Sisk has delivered many vital building projects across Ireland, the UK, and throughout Europe. In doing so, it provides valued employment and contributes to economic growth and urban renewal wherever it works.

“Construction is never just about bricks and mortar — it’s about people, communities, and creating opportunities for future generations.”

Sisk employs over 2,500 people across Europe and has been in existence for over 165 years.
