LIGHTWELL Project

Apr 1, 2022 - Jun 30, 2024

Background

Developed by GALILEE DEFENSE (Unibail-Rodamco-Westfield group), LIGHTWELL is a heavy restructuring project of the Galilee office building (ex PB15-PB16) located in the Michelet district in Paris La Défense, between the Esplanade du Général de Gaulle and the Cours Michelet.

A first phase of preliminary work, including cleaning and abatement of the existing building, was launched in 2020.

Actors

Owner: Galileo Defence (Unibail Rodamco Westfield Group);
Contracting authority: Espace Expansion (Unibail Rodamco Westfield Group);
Architect: Barthélémy-Griño Architects;
Master of Execution: SCO;
Logistics Company/ Demolition/ Major Work and CCFN referent: Small (Vinci Construction).

Construction Progress

The site will have two tower cranes located in the heart of the island inside the building. A site right-of-way will be located in the Voie des Sculpteurs and the cantonments will be installed inside the building. As a result, rights-of-way over public space will be limited. The existing pedestrian paths (access, passageway etc.) are maintained but will be slightly modified as the site progresses. We will communicate this information to you in advance of these different phases.
