Sample column structure of 'Printfrastructure', 3D printed reinforced concrete. In 2021, a UK first, on-site 3D reinforced concrete printing was deployed by HS2 Ltd’s London tunnels contractor SCS JV (Skanska Costain STRABAG Joint Venture). ChangeMaker 3D combines the 3D concrete printing process with the strongest material ever tested: graphene. Concrete with microscopic strands of graphene only several atoms thick running through it like stripes in a stick of rock replaces traditional steel to help drive improved site safety, greater construction flexibility, shorter build time and a smaller carbon footprint.

The Michelin Building, commissioned by the Michelin Tyre Company Ltd. as their first permanent British headquarters in 1909, opened in 1911.
