An eco-responsible head office: architecture and design of the new 3E Concept building

Guillaume Da Silva, interior architect based in Lille (Roubaix, France), was commissioned to design the interior spaces for the offices and restaurant of 3E Concept's new building. The project is part of a passive building designed by Roubaix architect Bertrand Wibaux and built by Carré Constructeur. An architectural challenge combining energy efficiency, well-being in the workplace and customized interior design.

An innovative architectural project for well-being

This project is above all the fruit of a dynamic collaboration between the client, the architects, the builder, the design offices and the landscape architect. Driven by a managerial vision focused on the well-being of his 50-strong workforce, Guillaume Leymonerie, head of 3E Concept, wanted open, bright spaces conducive to exchange.

The office layout has been designed to encourage cross-functionality while preserving areas of privacy. Inspired by the principles of Feng Shui, the interior design features natural materials and uncluttered volumes, creating a soothing, functional atmosphere.

The passive house, which consumes four times less energy than a building complying with the RT 2012 standard, illustrates a strong commitment to sustainability. This architectural project combines energy efficiency and occupant comfort.

A food court designed for conviviality

The company restaurant fully embodies the spirit of this project: a place for sharing that encourages interaction between office and production teams. Equipped with an XXL kitchen, this dining room offers employees the chance to enjoy a healthy lunch and self-service coffee beans, a convivial ritual introduced by the manager.

To bring a touch of authenticity and recall 3E Concept's former headquarters, located in a renovated farmhouse, cement tiles were integrated into the decor, giving the space a strong graphic identity.
