Permasteelisa Group CEO Liam Cummins said: “Being chosen by Multiplex to deliver such a prominent project in the city, highlights our capability as a market-leading facade specialist.  

“We have delivered many projects in the capital over the years, and this will be a fantastic addition to our portfolio.” 

The facade, spanning 15,500m², is designed to minimise solar gain while maximising natural light, contributing to the building’s sustainability goals.  

Permasteelisa’s design centre in Italy is currently finalising the facade, which will be assembled at the company’s manufacturing facility.

In addition, the building, to be situated near St Paul’s Cathedral, will feature operable windows for natural ventilation and facilities that encourage active lifestyles.  

Specifically, it will have fitness, cycling and commuting facilities, with a dedicated Wellness Wing entrance at street level adjacent to Cycleway no 6. 

Permasteelisa Italy executive general manager Nicola Calzolari said: “For Holborn Viaduct, in Italy we are designing a technologically advanced and bespoke fasade that will help realise the potential of the scheme’s environmental credentials.  

“Our colleagues in the UK will start the installation at the end of March next year, with an expected completion date of March 2026.”
