The comprehensive expertise of seele was in demand here for the 16 different types of façades. Aluminium façade elements with a high level of thermal insulation were used for most areas, with different forms and dimensions to suit each location. For example, the four trading floors, and hence the associated façade elements as well, are each 1m higher than the other upper floors. The ground floor has a tall post-and-beam construction glass façade; the atrium façades are also made of glass. A cold façade conceals the plant on the roof.
One further challenge was the demanding logistics during construction. Storage space is rare in the centre of London and so most of the façade elements were delivered to site virtually fully prefabricated, according to a just-in-time schedule, then transported directly into the building and erected from inside. Thanks to its global experience, seele is able to make use of the very latest on-site facilities. Erection work could therefore proceed quickly and safely, while causing only minimum disruption to London’s traffic.Project images: © John Madden
