The D2 Tower is located in a very constrained urban area, alongside the ring road at La Defense near Paris (3,000,000 sqm of offices for over 180,000 employees).
Its complex shape and structure generates 3 major frontages with its surrounding: a high tech prow pointed towards Paris, a thin overlooking figure towards Courbevoie, and a gentle curved rear abutting the ring road.
Built to a total height of 180m, it is designed to accommodate 3,700 people on 37 floors.
The D2 tower is the first composite load-bearing structure at La Défense with a metal exo-structure, enabling 30% of material economy. Its skeleton consists of a reinforced concrete core as well as an external steel mesh. The tower’s external ‘diagrid’ structure gives the building a diamond-like shine with a unique lighting effect.
