Canopy on the ground floor covered with a white Alucobond Plus skin for the Eria Tower in La Défense

The ERIA tower, 55 m high over 13 floors, brings together 25.000 m² of offices and 5.000 m² of shops in La Défense.

The project led by ALTAREA and designed by the architect Christian de Portzamparc, was born from a desire to optimally adapt the building to the shape of the land to create high quality office floors and embody a vision of the office of tomorrow and new ways of working.

Its ground floor facade extends the urban front and installs shops and a coworking space. It is clad with 900 m2 of ALUCOBOND Plus panels in the Pure White 100 shade, laid like a cap.

The high-rise building is located in the town of Puteaux at the foot of the La Défense district and at the corner of Bellini and Arago streets. In this district where the works are characterized by their verticality, the ERIA tower stands out for its architectural originality and audacity unique in its kind, adapting optimally to its host site.

The building has offices, internal services such as an inter-company restaurant, a coworking space and car parks and adds 160 m² of shops. The choice of the fan-shaped plan, “a heart and three petals”, makes it possible to offer three perfectly lit wings and distant views.

This petal structure multiplies the facade surface and guarantees an economy of circulation spaces. Between each petal, a set of terraces planted in cascade marks a vertical progression and reveals the natural beauty of the sky.

The three small towers are clad in glass dihedrals that reflect light. Some areas, meanwhile, are made up of two different glass skins. The singular silhouette composed of three thin wings is an urban landmark clearly visible from the circular boulevard and the slab of La Défense.

900 m2 of ALUCOBOND Plus panels were placed in a cap on the facade awning on the ground floor of the tower. The awning required bending and rebuilding of the panels.

The facade was laid out very easily and quickly thanks to the HICAD-ALUCOBOND 3D modeling software solution.
