This technical lecture outlines the design approach and technical challenges in delivering HYLO, a high-rise development at the heart of London, whose project team was awarded for full exploitation of an existing structure to maximise retrofit potential at the 2022 Structural Awards.

This technical lecture uncovers HYLO, the co-winner of the 2022 Supreme Award for Structural Engineering Excellence. This groundbreaking retrofit project transformed a 16-storey 1960s building in a radical way—extending it vertically by 70%, adding 13 storeys, and effectively doubling the leasable area. Remarkably, the existing frame and foundations were entirely reused, with only essential strengthening undertaken.

The project team outlines how a detailed investigation and back analysis of the existing structure informed the design of the extension structure, allowing for targeted strengthening and the strategic reuse of foundations.

Watch the recording to find out more about the vital role of investigations and back analysis in maximizing the reuse of existing structures and the inherent benefits of retrofitting compared to demolition and rebuild.

Speakers

David Watson, Technical Director, AKT II
David co-leads AKT II in matters related to Climate Action. He focuses on adaptive re-use, design efficiency and material innovation. Beyond HYLO, he has worked on the Stirling Prize nominated 100 Liverpool Street, the rejuvenation of the world’s first cast-iron framed building at Shrewsbury Flaxmill Maltings and the new home for the Museum of London at West Smithfield.

Michael Hynd, Technical Director, AKT II
Michael’s experience encompasses some of AKT’s highest-profile commercial, high-rise developments and retrofit projects. Beyond HYLO, Michael has worked on the Stirling Prize winning Bloomberg European HQ, which assimilated several existing pile foundations within a constrained site, and the 45-storey Highpoint Tower. He is currently the project lead on the extensive retrofit and enhancement of the former BT centre at Panorama St Pauls.

James Kingman, Associate team leader, AKT II
James has worked on many of AKT’s landmark developments throughout London, the UK and internationally. He specialises in structural engineering and computational design.
