Clough was founded in 1919 by John Oswald Clough.
From inception through to the 1950s, Clough forged a reputation as a quality construction company in its development of schools, and residential and commercial properties throughout Perth.

Diversification was again the order of the day in the 60s, as Clough entered and embraced the Mining and Energy industries. Today, Clough works with many of the world’s largest companies to provide engineering, construction, commissioning and asset support services for some of the largest, and most challenging resource projects around the globe.
