Eckersley O’Callaghan is an award winning engineering design practice. We enjoy working with a range of materials, forms and building types across diverse sectors and project scales to deliver imaginative solutions. We have developed an international reputation for our structural glass designs as well as our work with steel, concrete and timber. From our offices in London, Paris and Shanghai, our structure and facade teams collaborate closely with architects, designers and clients throughout the UK, US and across the world.. Our service is strengthened by close collaboration with Eckersley O’Callaghan and Partners LLC, based in New York, who offer a similar range of engineering design services for North American projects and clients. Eckersley O’Callaghan was formed in 2004 by Brian Eckersley and James O’Callaghan after many years working separately as Chartered Engineers. Both founding Directors complement their structural engineering experience with a background in architecture. They have built a team of the highest calibre, now over 30 strong.
