The strong character building is enhanced by a precise selection of construction materials:

- White concrete provides clarity and precision: at basement level (smooth and bush-hammered) and north facade overlooking the street. The choice of white concrete gives unity to components, brightness on the north elevation.

- Bush hammered concrete with champagne metal finish recalls the warmth of Montpellier stone, to form a backdrop.

- Steel at the level of the continuous balconies, punctuated with perforated white railings on the south elevation overlooking the park. A double skin also reflects light in elevation.
