James O’Callaghan is a structural engineer with over 20 years of experience. He co-founded engineering design practice Eckersley O’Callaghan with Brian Eckersley in 2004. The practice is based in London, with offices in New York, San Francisco, Paris and Shanghai.

Widely acknowledged as an authority on structural glass, James is perhaps best known for his highly innovative designs for glass stairs, bridges and other structural elements in Apple’s iconic stores around the world. Recent projects include those in Dubai, Singapore and San Francisco as well as Apple’s landmark headquarters in Cupertino. The practice’s expertise in the use of glass as envelope led to the formation of a dedicated facade engineering service which supports clients with projects of all facade systems and typologies.

James is a member of Design Council’s Sounding Board and HS2 Design Panel. He teaches at Portsmouth University and is Visiting Professor at TU Delft. In 2016, he was awarded the IABSE Milne Medal for excellence in structural design.
