Webb Yates Engineers were appointed to design the roof structure to the new 22,500 seat stadium for Brighton and Hove Albion Football Club. The stadium is a bowl form with a three tier west stand and single tier stands to the other sides. The roof form is designed to imitate and blend into the local undulating topography with a curved cylindrical form. The roof structure is supported by two raking opposing trussed arches with ties and props down to the roof surface and supporting structures below. The elegant and efficient roof spans across the whole stadium with a mere 100kg/m² of steel.
