The Kléber Étoile project was born out of the reinvention and association of three office elements which between them tell the story of 20th century architecture.

The main challenge was how to make the best use of the grandeur of each individual architectural narrative and create an elegant and fluid building which would meet three requirements : value optimisation through the creation of floor area, compliance with contemporary standards for office buildings and the reinforcing of the heritage dimension of the whole.

The renovation of the entire 11,000 sqm. complex was carried out in several phases and in occupied premises.

Landscaping of the property was primarily focussed on the central garden and terraces.
