The sculpture is being manufactured in Italy and Switzerland where architects dRMM and engineers Arup have worked with specialist teams to test the strength of the material and develop the design to allow public access on the structure.
The CLT panels are being made by Italian firm Imola Legno, while Swiss company Nüssli is building the structure and will erect it in London.
The sculpture was to be installed outside St Paul’s Cathedral but the London Design Festival team has decided the best location is on the lawn in front of Tate Modern – a move that’s been welcomed by the designers.
dRMM director Alex de Rijke said Tate Modern’s programme of modern art and architecture, combined with the site’s Thames panorama of London, provided a context to which the installation "can make a distinctive contribution".
