Eckersley O’Callaghan

Structural and Facade Engineers


What we do:

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

The consultancy is now regarded as the world’s leading glass engineer working on prestigious projects around the world.

These range from the world’s largest single-dome greenhouse in France to high-profile developments at Oxford University and work on Google’s new London headquarters at King's Cross. Its 15-year working relationship with Apple means EOC is named in 20 global patents.

This enviable international reputation results from the team’s commitment to research and innovation.

The aim is to constantly explore the potential of new materials and structures leading to buildings that create a sense of well being or inspiration in those who work in them or use them.

Why we do it:

Working at EOC is an opportunity to be involved in an incredibly diverse range of projects, with great opportunities to travel and see the world.

The team has created public sculpture, designed new flagship retail stores, redeveloped and refurbished listed structures, devised intelligent infrastructure solutions and engineered new housing, from private residences to residential towers. Many are projects with profound social and ecological value to local communities.

Working together, both within the design team and with contractors is key to achieving great results.  If everyone is working towards a common goal the experience is incredibly rewarding.

The company puts great importance in the wellbeing of its workforce conducting staff surveys to monitor job satisfaction and mental health and organises regular team outings.

It’s a team that works hard and plays hard too.

The People who do it:

Eckersley O’Callaghan’s leadership team includes some of the industry’s most influential engineers. Their expertise is valued by research institutes, technical conferences and numerous design panels.

Together they lead a team of designers, engineers and technicians with a wide range of skills, working from offices in London, New York, San Francisco, Paris, Hong Kong and Shanghai.

This collective experience and geographical spread mean EOC works on some of the most complex and demanding projects across a range of scales and budgets all around the world.

Into the Future:

As a relatively young business, EOC has grown significantly due to its approach of leading research into new materials and their structural use.

With this continued approach, allied to a team of the very best people, the company sees a very bright future ahead.
