St Pancras International, London - Alumasc Rainwater Apex Cast Iron

Apex Heritage Cast Iron rainwater system from leading specialist Alumasc was commissioned as part of the £800 million extension and restoration of St Pancras International, London.

The extension and interior of the station comprised all the modern facilities expected in Britain’s most advanced station, however, work on the oldest Grade 1 listed part of the station called for the faithful and painstaking restoration of the gothic red brick façade, to retain the original detail of George Gilbert Scott’s design.

Existing rainwater systems, despite being almost 150 years old, were still in use. As part of the redevelopment project English Heritage insisted that any new rainwater details must faithfully reproduce the original patterns of the Victorian rainwater goods used when the station was first built. Alumasc worked closely with the main contractors to produce bespoke moulds, creating cast iron replicas of all the existing pipes and hoppers to take away rainwater from the vast single span roof, which is still the largest of its type in the world.
