The Company’s building housing expertise

The company’s first venture outside Merseyside was the construction of workforce accommodation for a steel company at Redcar, northeast England, during the First World War. But it was a move south to build houses in the booming suburbia around 1920s London that really sparked the family firm’s expansion. Costain became known both for the construction of large ‘gentleman’s residences’ in leafy Surrey and estates of more modest dwellings such as that built to house Ford’s workforce at Dagenham, Essex.

Our housing expertise found its greatest expression in the construction of Dolphin Square in London’s Pimlico. The largest block of flats in Europe at that time, the first 600 apartments were ready for use just a year after construction started in 1935. The second phase contained innovations not only in the swimming pool, squash courts and restaurant contained within the building but in its novel centralised heating system, involving waste heat being piped from Battersea Power Station on the opposite bank of the Thames.

Expansion overseas

The 1930s saw Costain move overseas for the first time. A contract to build an 11-mile section of the Trans-Iranian Railway through the Alborz Mountains was discovered – remarkably, only after the deal had been signed – to require long stretches of tunnels and viaducts, rather than conventional railway construction. The contract made a substantial loss, but the company’s technical prowess in driving through such difficult terrain greatly enhanced its reputation. Iran was also the site of Costain’s first foray into petrochemicals, with the building of the refinery at Abadan in 1938.

The Second World War – and its aftermath

Costain helped to create the remarkable Mulberry floating concrete port that was towed in sections across the English Channel to give the Allies a logistics foothold in France in the days following the D-Day invasion. And when peace returned, thousands of semi-permanent Costain-constructed concrete houses designed to last for a maximum of 30 years continued to give service for a decade beyond their estimated lifespan. Post-war, grey, austerity Britain was enlivened by the Festival of Britain site on the south bank of the Thames, constructed by Costain.

International challenges – and successes

Expansion in the Middle East continued, with the creation of a 10 million gallon-per-day water distillation plant helping transform Kuwait from a small fishing port into a modern city. Links with Kuwait continue to this day, with the influential Kharafi construction family holding a major stake in the company. Airports in Bahrain and Dubai followed, as did the world’s largest dry dock and the Middle East’s largest deep-water port in Dubai.

We have built airports, petrochemical plants, waste treatment works and schools – creating the building blocks of modern life and improving the quality of life of the people who use them!
