Lagan Group


Founded in 1960, on the outskirts of Belfast, the story of Lagan is one of vision, pragmatism – and perseverance. Today, more than 55 years later, we are one of the UK and Ireland’s leading construction businesses with expertise across a wide spectrum. This is how we did it.

Our story begins with one man and an ambitious idea. Peter Lagan was already running a successful haulage business when he identified an opportunity to diversify. In 1960, he bought the Whitemountain Quarry in Northern Ireland and the Lagan Group was born.
