The first tower in the Faubourg de l'Arche district, built in the late 1990s, the Cèdre tower has been transformed. It was replaced by the Emblem tower in 2021. Following the departure of EDF in 2019, the tower underwent restructuring to make it more environmentally friendly and meet the new expectations of users. Today, employees working in Emblem enjoy a rooftop terrace on the 26th floor, renovated spaces, a double-height lobby, and parking spaces for electric cars and bicycles.

Its contemporary appearance retains the codes of its first version, revealing its tinted windows and playing with two materials: glass and stone. The panels from the old façade were reused and deposited by a European Union reuse channel. The new ones are made of ultra-high-performance fiber-reinforced concrete, which refines the tower's silhouette and makes the façade more durable.

The Cèdre tower was designed by Conceptua, an agency founded by architects Michel Andrault and Nicolas Ayoub. They also designed the Egée and Adria towers. After its acquisition by RedTree Capital, the Wand division of the JLL group, which specializes in architecture, redesigned the tower. JLL - Wand is committed to giving buildings a new lease of life, making them more sustainable and in line with the new uses of employees. Here, the wishes of the architects of yesteryear are respected: the neutrality of the architecture becomes a quality because, inside, it is synonymous with flexibility.
