Brian Eckersley and James O’Callaghan founded Eckersley O’Callaghan in 2004, with a shared vision of a structural design practice that truly integrates engineering and architecture.

Since then our team has grown to 130 across offices in London, Manchester, New York, San Francisco, Los Angeles, Paris, Milan, Hong Kong, Shanghai, Delhi and Sydney.

We have established an international reputation for our creative, yet rigorous, approach to engineering structures and facades.

We work on a range of extraordinary building projects across the world, from complex structures of timber, steel or concrete, through to specialist heritage projects and advanced materials such as glass and carbon fibre.

Our engagement with architecture and industry underpins our pioneering use of materials to realise projects of exceptional quality, efficiency, and elegance.

Sustainable thinking informs all our projects, beginning at the earliest conceptual stages and continuing right the way through to completion.
