Tea manufacturing facility and headquarters in Dreux: design and construction by GSE

An ambitious project driving modernization and sustainability

Since establishing itself in Dreux in 2011, Dammann Frères—a leader in the manufacture and distribution of teas and herbal infusions—has become a key player in the sector. Faced with business growth and the obsolescence of its current 30,000 m² building, the company decided to invest in a major project: the construction of a new headquarters and a modern 27,000 m² production facility.

With this project, Dammann Frères aims to own its premises while integrating sustainable, innovative concepts to address environmental challenges. Key priorities include respecting the environment, managing the carbon footprint, and ensuring optimal food-processing workflows. The new facility also significantly improves employee working conditions through abundant natural light, carefully engineered acoustic and thermal solutions, and an overall more pleasant environment.

Functional and aesthetic architecture at the heart of the project

The architecture of the new headquarters and factory blends tradition and modernity to reflect Dammann Frères’ identity. The building stands out thanks to brick facades, modern curtain walls, and a central patio that adds an aesthetic and welcoming touch.

At the same time, the project is perfectly structured around the functional requirements of food processing operations. Dedicated areas have been created to meet production needs, such as zones for blending, dedusting, and other key stages. The flow of operations is designed to adhere to the principle of linear progression, ensuring both efficiency and hygiene.

The offices feature an interior design by GSE, with special attention paid to the furniture layout and the surrounding landscaped areas. The on-site shop—a true showcase for the brand—is enhanced by the high-quality design of the central patio, creating a pleasant experience for employees and visitors alike.

Innovation and energy performance for a BREEAM-certified building

The new Dammann Frères facility is designed to be at the forefront of innovation and environmental performance. With a “BREEAM Very Good” rating, the building boasts energy consumption 20% lower than the thresholds required by the RE2020 standard, thanks to advanced technological solutions. The installation of photovoltaic panels, combined with optimized management of industrial fluids and process equipment, demonstrates the company’s commitment to a more sustainable future.

The design also incorporates advanced technical management systems—including BIM, a Building Management System (BMS), and air-to-water heat pumps—to ensure optimal maintenance and energy efficiency. The project was developed from scratch and included full management of administrative procedures, such as preparing applications for building permits and ICPE (Installations Classified for Environmental Protection) authorization. Dammann Frères thus positions itself as a forward-looking company that aligns with today’s priorities by combining innovation, sustainability, and quality.
