In pictures | How Mace’s retrofit of Euston Tower will look

The redevelopment has been designed by Danish architect 3XN in collaboration with London-based Adamson. Arup will deliver the structure and MEP.

Ged Simmonds, managing director of private sector at Mace Construct, said: “This world-class science and technology building with new offices and lab-enabled workspaces will exemplify our expertise in delivering retrofit developments of this scale.

“By incorporating sustainable practices and cutting-edge engineering, we are not only showcasing the potential for forward-thinking office redevelopments, but also highlighting how reuse strategies can drive circularity in construction.”

David Lockyer, head of development at British Land, said: “Following planning approval last week, we are pleased to be working with Mace to deliver this incredible scheme – the first West End tower in a generation, and likely to be the last.”

Completion is expected at the end of 2030.
