In the Limelight – Lefteris Karpozilos

It’s been a while since we highlighted one of our talented team, but it’s worth the wait. Lefteris – our London Project Engineer – has big ambitions from seismic roots…

Why did you become a structural engineer?

Growing up in Greece – one of the most seismically active regions in Europe – sparked a particular interest in seismic-resistant design and the engineering behind tall, slender buildings. My father, also a structural engineer, exposed me to real-world construction through frequent site visits, which allowed me to understand the integration of design and construction phases. The ability to create long-lasting structures that contribute to the built environment continues to be my primary motivation in this profession.

What’s the most exciting or interesting project you have worked on for Peter Dann?

One of the most technically complex and rewarding projects I’ve been involved in at Peter Dann is the Verney Road redevelopment. The scheme involved the extensive refurbishment of an existing warehouse frame with internal mezzanine, requiring selective removal of bracing and columns, new steel insertions, lift pit installation, slab openings and roof alterations. The project required a holistic assessment of the global structural performance, with interventions across multiple materials – steel, reinforced concrete, masonry, timber and piling. The multi-material coordination, temporary works sequencing and adaptability of the existing frame made this project both challenging and intellectually engaging.

What key advice would you give a graduate?

Build a solid understanding of core structural engineering principles – analysis, design and behaviour of materials – as well as the relevant design codes and standards. Familiarise yourself with the RIBA stages and understand how structural inputs evolve through the project lifecycle. Do not rush into complex tasks; instead, focus on mastering fundamentals and take every opportunity to visit sites and observe how designs are realised in practice.

Where do you see yourself in ten years’ time?

A well-rounded structural engineer with a strong portfolio of technically complex and diverse projects. I aim to be in a position where I can lead structural design on major developments, contribute to strategic decision-making, and add value through a deep understanding of structural systems, sustainability and constructability. I also hope to be actively involved in knowledge-sharing within the profession – whether through mentoring, technical writing or engagement with professional institutions – while continuing to grow and adapt in an evolving industry.

What would be your dream project?

Rather than a specific project type, my aspiration is to work on structurally challenging developments across various regions globally. Designing at least one major project on each continent would allow me to […] enhance my technical adaptability but also offer a broader perspective on global engineering approaches – while continuing to do what I am most passionate about: structural design.
