Our vision

Quadrilatère works on the design and implementation of smart, fulfilling work spaces, aligned with the company’s values, and conducive to employee wellbeing and performance.

Our background

Quadrilatère was founded in 1989 by Jérôme Malet, a lover of architecture and design, with experience at Christofle and Cassina. At the outset, the company acted as the interface between furniture manufacturers all over the world and their clients. The company soon expanded its scope of action to custom layout, through relationships developed by Jérôme Malet with architects and designers.

Today, Quadrilatère still works closely with architects and designers for the creative design of certain projects. In this case, the company offers its sensitivity and expertise to ensure a development consistent with the creative project and consistent quality from design to completion.

Quadrilatère has nevertheless developed its own Design division, which now comprises around ten architects and interior designers, enabling it to support its clients in the “global” development of their spaces: advice, design, work and furniture.

Since May 2025, Christophe Gellé, former president of Réponse and C&W Design+Build, has taken the helm of Quadrilatère to support the Group’s development, and more specifically, to extend its spectrum of activities to the hotel and tourism sectors.

Quadrilatère remains faithful to the two key focuses promoted by its founder: respect for architects/designers and their work; and the ambition to be sustainable, thanks particularly to the quality of the work completed.

Our 4 pillars

ATTENTIVE & RESPECTFUL

Quadrilatère firmly believes that a company is a structure with people at its heart, made up of a multitude players. Rapport and listening are therefore the basis of our working method : the needs and objectives of our clients are carefully analyzed and respected, as are the values ​​of the company that commissioned us, in order to give body to a project that resembles it.

Listening carefully and without preconceived ideas to our clients enable us to understand them beyond their stated objectives, and to offer them a solution that is not a copy and paste of another project.

INNOVATION

Quadrilatère has been innovating continuously since 1989 to establish itself in an ever-changing sector and to fully meet its customers’ needs. Hired for smart, fulfilling projects, the teams are constantly on the lookout for innovations in architecture, construction technologies, sustainability, management of organisations, and workplace sociology, etc.

Quadrilatère is a living ecosystem, constantly in motion, which is articulated with and around a multitude of experts to create efficient and intelligent places.

METHOD

Quadrilatère works on all aspects of the value chain, beginning with an understanding of the client’s challenges and the specific features of the site (its orientation, structure, position within the building, etc.). Once this input data has been analyzed, Quadrilatère’s teams detail all the technical components of the project: acoustics, lighting, furniture, sensory perception, etc. They then structure the execution of the work, relying on strong partners, carefully selected according to the project’s characteristics.

While Quadrilatère obviously applies highly detailed, structured, and professional work processes, the company is nevertheless very flexible in its project methodologies to remain constantly attentive to the client’s expectations and the specificities of their project, adapt to their constraints, and thus respect their corporate culture.

TANGIBLE

Quadrilatère is a pragmatic actor, anchored in reality.

What we offer our customers has to be achievable and work perfectly. It is because we know our business, the technical and operational constraints, the functional expectations of our customers, that we are able to design easily executable projects.

Quadrilatère provides a comprehensive service, from design to delivery, and even beyond through the ten-year liability insurance. The company is committed to the quality of the work, prices and deadlines. As the only point of contact for the contracting authority, Quadrilatère coordinates all the project stakeholders and is therefore responsible for its success.
