Welcome to 150 Holborn

150 Holborn is Sidara’s new London headquarters, designed and developed by us and for us by harnessing the expertise of our collective member firms and bringing many of our colleagues in the UK together for the first time.

Our professional services – planning, architecture, engineering, sustainability, energy, cost consultancy, project management, building surveying and a range of specialist advisory services – are now all under one roof in a centre of multi-disciplinary expertise in a key global hub.

There are very few organisations in London that develop and occupy their own building as we have done. A truly collaborative Sidara inter-company design and delivery, we are stronger together. Have you visited one of the smartest buildings in London yet?
