From its roots in Cork in 1859, the Sisk group - today made up of construction firm Sicon, Korine, a property management firm, and Origo, a third retail distribution business - is one of Ireland's largest private companies.

The firm is owned by Dublin-based brothers, sailing fan George, Henry and John - and members of their families. Owen, JP and Richard Sisk are directors.

In 2016, the entire business took in €1.1bn, on which it booked a €9.3m profit, while its most recent accounts for 2017 showed turnover fell to €943m, but profits rose to €20.6m, after a decision not to pursue low-margin construction projects. All three businesses are likely to be prospering on the back of the booming construction sector - particularly for commercial properties and data centres, shops and factories - while consumer spending and property values are rising.
