We are committed to maximising success for our customers in every commercial project we deliver

Based on our history of proven delivery on large and complex office projects, along with our continually innovative and collaborative approaches to each project’s challenges, John Sisk & Son’s experience in the commercial building sector has always offered confidence to our clients.

In leading commercial cities around Ireland and the UK (Dublin, Cork, London, Manchester, Birmingham) our ability to work in tight locations has enabled us to deliver an extensive range of iconic offices and mixed-use developments, and we are recognised by our global customers as world leaders in safe and effective delivery.

Our status as Ireland’s long-term number one provider of construction services has been extensively earned through decades of operations across Ireland, the UK and mainland Europe. Ever since our earliest beginnings in 1859, John Sisk & Son has always trusted in the skills and vision of our people to drive our relentless spirit of innovation.
