Eckersley O’Callaghan is a multi award-winning engineering design practice. Since forming in 2004, we have grown to over 120 strong with offices in London, Manchester, New York, San Francisco, Los Angeles, Paris, Hong Kong, Shanghai, Sydney and Delhi. We work on a range of extraordinary building projects in the UK and across the world, from structures in timber, steel and concrete, through facades and bespoke glass structures to specialist marine design.

We have established an international reputation for our creative, yet rigorous, approach to engineering structures. Our engagement with architecture and industry underpins our pioneering use of materials to realise projects of exceptional quality, efficiency, and elegance.

We are well known for collaborating with Apple on all of their flagship projects around the world. Our innovative use of glass and carbon fibre reinforced polymers, as well as sensitive adaptations of historic buildings, have become signature features of the brand.
