Walsh Wins At Structural Awards 2023 for 9 Millbank

Complex repurposing, refurbishment and re-use project receives prestigious award for “Diligence and Rigour in Maximising Reuse”

9 Millbank is a luxury residential led mixed-use development which was a hybrid refurbishment, reuse and rebuild project on a historical and complex site.

It required our engineers to employ a comprehensive range of structural engineering skills to deliver the client’s vision. We had to challenge the status quo and undertake a journey into engineering history and negotiate with third parties whilst designing out complications through innovative foundations and lightweight structures. As well as the structural design, we conducted complex site investigations, designed remediation solutions and specified innovative products.

This delivered significant cost, programme and sustainability savings to the client, St Edward, as well preventing possible disruption to significant Westminster buildings. The project is being used as an exemplar project to educate students and industry titans on the benefits of the circular economy.

The judges felt that our team fully embraced the circular economy approach by reusing and repurposing all of the existing 9 Millbank building instead of just retaining the façade. We respected, retained and reused ground structures of historical engineering significance including the superstructure and power station substructure, documenting these for generations to come.

Thorough research yielded impactful outcomes. The project team have demonstrated excellence in research and site investigation which minimised risks, reduced costs, reduced programme and deliver a more sustainable approach.

“This project is an exemplar in engineering tenacity and thoroughness. The team had to deal with real complexity to try and arrive at the lowest intervention solution. The team fully embraced the circular economy approach by reusing and repurposing all of the existing 9 Millbank building instead of just retaining the façade.”
