The 32 is a 3000 m² building, in the Paul Duez street in Lille. It was heavily renovated into a very eficient office from an energy point of view and an ecological perspective.

Architectural descriptionThe facade of the building of the old post office is cleaned to reveal the original stone. The roof is adorned with an extra level. A crowning glass which wants quiet day, reflecting the color of the sky, illuminated at night to catch the eye and be part of the dynamism of the Euralille district. The new office building follows the simple and classic aesthetics of the street front building. Their joint service is carried out by the rue Paul Duez.
The housing construction is constituted of a series of layers stacked one on the other in an offset manner. Facades, dressed in a gray-brown siding, assume the monolithic appearance of the building. Access to housing is made from Moulins street Garence after crossing a garden leading to the entrance hall. The proposed typologies are oriented southwest and east. They range from T1 to T4, promoting social mix.

Reasons for participating in the competition(s)Le projet prend place sur une parcelle jouxtant à la fois la rue Paul Duez et la rue Moulins de Garence. L’enjeu figure dans la création d’un programme mixte de 15 logements collectifs, de bureaux neufs ainsi qu’une réhabilitation notamment énergétique de bureaux : l'une des premières certifications BREEAM de la métropole lilloise.
Création de trois bâtiments contigus : les anciens bureaux de la Poste réhabilités rue Paul Duez, le nouveau bâtiment de bureau adjacent à la partie réhabilitée, et un bâtiment de logements donnant sur la rue Moulin de Garence. Une partie du bâtiment côté cour fait l’objet d’une démolition afin de créer une série de cour anglaises en coeur d’îlot, assurant l’éclairage du rez-de-chaussée bas du bâtiment existant et du parking souterrain.
