Our group

Engineers and architects
We firmly believe that these two disciplines depend on each other.
To develop tomorrow's lifestyles, which will closely combine the technical and the aesthetic, we favor a systemic and transverse approach that is a great source of creativity.
It is from its French roots that the Arching Group derives its sense of challenge, demand and creativity. Our desire is to offer an innovative and visionary alternative to improve today's life with the technologies of tomorrow. Our trademark is versatility. This helps our teams to provide optimized solutions for even the most complex of our clients' demands.
It is precisely this vision, shared by our 300 engineers, architects, developers, designers, economists and project managers, that holds together our teams based in Paris, Lyon, Warsaw, Beirut, Hong Kong and Shanghai.

Our vision

Our driving conviction is that people must be at the center of each project. The capital H in the very center of our name reminds of that every day. Anticipation of our clients' demands and the challenges of tomorrow are the driving forces behind our contribution to the quality of life.

We make ourselves listeners to territories and local cultures. We design and realize buildings, houses, offices, business centers, factories, hospitals, laboratories and even entire districts, by putting ourselves in the position of those who will be using them

Our story

The best stories are always born of great meetings. The story of Arching is one about the coming together of two areas of work, being the fruit of the association between the industrialist Leon-Jacques Salmon and the architect Bertrand DE Lagarde.
In 2006 these two men, both former students from Northern France, found themselves being driven by the same idea; a better world could be built using an innovative offer that brought together engineers and architects with a French culture. Synergy of ideas and shared ambitions... the points of view and the motivations came together.
In that same year the Manufaktura project, which transformed an old 27-hectare disused industrial site in Poland, implemented by SUD Architectes (2008 ULI prize for the best European Business Center in the "very large" category), saw the light of day and confirmed the importance of bringing together architects and engineers as well as the efficiency of that formula. From that idea, Arching was born.
A name adopted in 2012 ; Sud Architectes becoming its architectural signature.
Those who work in our group's companies continue to rewrite this story day after day, expressing our vision to clients the world over. With their talents, sensitivity and work ethic, they help spread the Arching spirit far and wide.
