Deerns at a glance


Who we are

The technology with which we surround ourselves is becoming more complex and more intelligent. We see this in the buildings where we live and work and in the infrastructures through which we move and exchange information.

This rapidly changing world needs a vision which reaches beyond today’s challenges. We need ideas that respond to growing global prosperity, to the need of more people for a comfortable and healthy living environment, and to the concerns of climate change and resource depletion. In short, we need ideas with both vision and ambition.As an independent engineering firm which operates worldwide, Deerns has the capacity to make these ideas a reality. We establish lasting relationships with our clients so that we understand not just their questions, but their underlying needs and business processes. Moreover, to help our clients realise their vision, we combine our international network’s expertise and experience with local entrepreneurship and a solid cultural grounding in specific markets.

Thanks to this synergy, Deerns has done very successful project work for many Airports, Health Care organisations, Data Centres, Laboratory and Clean room users and Real Estate developers. And our innovative approach within the fields of building systems, energy supply and building physics has proven itself in every area of our service. From concept to design to supervision to aftercare: Deerns brings concepts to life.

Deerns was founded in 1928 and has almost 600 staff members spread across offices in The Netherlands, Belgium, Germany, France, Italy, Spain, The United Kingdom, Turkey, The United Arab Emirates, Brazil and The United States.
