For the yet to be constructed £63million Woolston waste water treatment plant on the coast near Southampton, the designer, not surprisingly, went for a wave-like form. Its curves will have to be accurately emulated by the roof and cladding, which have been designed by Prater, using its partner BEMO’s standing seam system – to suit the building’s relatively complex geometry. It will replace the existing building, which no longer meets Environment Agency standards, and solve the odour issues that have bothered the locals.
