James and Brian Eckersley formed the structural design consultancy Eckersley O’Callaghan in 2004 and have worked together to realise their shared vision of a pioneering structural design practice that truly integrates architecture and engineering.

The practice now has offices in London, New York, Paris, Shanghai and is active globally.

Acknowledged as an authority on the structural use of glass, James is perhaps best known for his highly innovative glass stairs, bridges, facades  and other structural elements in a range of Apple’s flagship retail stores including Tokyo, Sydney, Shanghai, Hong Kong, New York and London.

His ongoing interest in the development of structural glass design has led to the firm’s involvement with many challenging and award winning glass projects around the world.  This was recognised in the 2010 when the practice won the Queen's Award for Enterprise in the Innovation category.  James regularly holds informative sessions for industry wide professionals to pass on the experiences in design of glass.  He is regularly asked to be a keynote speaker at notable international glass industry conventions around the world such as Glasstech and Glass Performance Days.  The whole company is committed to R+D with staff regularly producing papers for publication.

Recently, James formed a Facade Engineering Group within the practice that specialises in high end facade systems, material research, geometry optimisation, energy mitigation and sustainability.  The group serves projects worldwide and aims to become a leader in this field of engineering.  Following his commitment to projects in Hong Kong and Asia, James became a Member of the Hong Kong Institution of Engineers in 2011.
