Following our earlier work on Phase 2 of the Battersea Power Station refurbishment, we were asked to deliver the glazed roofs to both the Boiler House and Turbine Hall.
The four large heritage roofs over the Turbine Hall and control room were originally installed in the 1930s. When we arrived, it was like stepping back in time; the original dials in the control room were still in place.
Working with the original steels, we designed and installed the new glazed roofs, each stretching some 60m in length from a new bespoke framed system. This was developed to mimic the original heritage profiles with new dies being commissioned. The complete system was fully developed, built off site and thoroughly tested. The new double-glazed units were made to replicate the Georgian Wired Glass with fritted glass pattern. Each glass panel was individually lifted into place by a gantry lifting device connected to the steel portal frame, making up a total glass area of 1,800 square metres overall to the Heritage roofs.
Situated between the four famous chimneys, the Boiler House is the main and most recognisable structure within Battersea Power Station. Working closely with Eckersley O’Callaghan engineers, we designed and installed the bespoke steel structure with each purlin weighing 6 tonnes and stretching 18m in length. These were brought to site on oversized delivery vehicles and each purlin was lifted individually into place via a tower crane. A total of over 125 tonnes of steel makes up the bespoke structure supporting the boiler house roofs.

Project Story Continued
We installed 1,000 square metres of glazing to the boiler house roofs. Each of the large glass panes are made using laminated Low Iron (Ultra Clear) glass forming the double-glazed units and weigh circa 1 tonne. The double-glazed units span between each purlin supported only on two edges with glass-to-glass joints, minimises the need for structural framework and allows unlimited light through into the atrium beneath. Each glass unit was lifted and placed into position via a tower crane.
The glass roof also includes a motorized louvre system, to help maximise the building’s energy efficiency and provides ventilation.
