Located in the Michelet district, the Lightwell project is the result of the restructuring of the Galilée building.

It offers unique visibility in the heart of La Défense, on the esplanade, in the immediate vicinity of the Parc project. The building is located equidistant from the two major public transport stations in the business district: Grande Arche de La Défense and Esplanade de La Défense.

This 'labour code' building is on a human scale and is spread over 10 floors. It offers a variety of work spaces that encourage concentration and creativity. Lightwell has a total capacity of 2,850 employees and includes flexible platforms of 2,800 sq.m. to 3,300 sq.m. each and direct connections to the outside world.

An architecture for meeting and well-being

The building has two strong architectural elements: a huge atrium bathed in light, where throughout the day, employees meet, have meetings or sit down for an informal chat. Lightwell also has a lively interior street. It offers a view of the green heart of the building and irrigates the main living areas of the building: the reception lobby and its adjoining coworking spaces; the atrium and its terraces with the agora at its foot and a café at the counter; a healthy restaurant space and its terrace.

1000 sq.m. of outdoor spaces and terraces will be created, including a 500 sq.m. rooftop.

The materials have been chosen to be warm and to make you feel at home: wood, on the floor and on the terraces, natural materials and colours... Everything has been thought out to put well-being at the heart of the user experience.

The building will offer two catering areas: a healthy restaurant open to the outside and a company restaurant in the spirit of a market, but also takeaway offers.

Lightwell will be equipped with a Business Center with a 200-seat auditorium opening onto a green patio and 4 sub-commission rooms. The building will offer a wellness area and outdoor sports classes, as well as a secure bicycle room with 65 spaces and a self-service repair area, changing rooms and showers.

An environmental benchmark that promotes resource conservation.

The building embodies Unibail-Rodamco-Westfield's "Better Places 2030" programme with very high environmental standards (target levels: HQE "Exceptional", BREEAM "Excellent" and BBC-Effinergie Renovation RT-40%).

Re-naturalisation, re-use and energy efficiency were the watchwords of the renovation, which demonstrates a global low-carbon approach (two-thirds of the existing structure was preserved, the façade was re-used in the terrazzo of the hall floor and the restaurant, bio-sourced and local materials were used, a bioclimatic façade, 100% LED lighting, energy recovery from the lifts' braking, etc.)
