Value proposition

Award-winning structural & facade engineers committed to delivering innovative and sustainable engineering solutions.

Eckersley O’Callaghan is an award-winning engineering design practice. Since forming in 2004, we have grown to over 140 strong with offices in London, Manchester, Paris, Milan, New York, Los Angeles, San Francisco, Hong Kong, Shanghai, Sydney and Delhi. We work on a diverse range of extraordinary building projects in the UK and across the world, ranging from conventional 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. This is exemplified by our innovative work in structural glass for Apple’s flagship stores around the world over the past decade.

We were awarded the Queen’s Award for Enterprise: Innovation in 2010, and in 2014 won the Institution of Structural Engineers'​ highest accolade - the ‘Supreme Award for Excellence in Structural Engineering’ for Apple Zorlu Glass Lantern, Istanbul. In 2016, we were recognised as Building Awards ‘Engineering Consultant of the Year'​.

We received our second Queen's Award for Enterprise in 2018, this time for International Trade, recognising three exceptional years of growth.
