Herzog and De Meuron
During the conversion of the former power station into waht is now the Tate Modern, Calcinotto was appointed to offer their services as an agent and to offer a site engineer service.
The power station consisted of a huge turbine hall, thirty-five metres high and 152 metres long, with, parallel to it, the boiler house. The turbine hall became a dramatic entrance area, as well as a display space for very large sculptural projects. The boiler house became the galleries. These are on three levels running the full length of the building. Above the original roofline of the power station a two-storey glass penthouse was added. The chimney was capped by a coloured light feature.
