Project Overview
The Multifunctional Workspace Building “FRITZ” is the third project completed in 2022 by Christ & Gantenbein Architects on the Roche Campus in Grenzach, following an office building and a technical facility realised in 2011. Named after the company’s founder Fritz Hoffmann, the building embodies Roche’s ongoing cultural transformation and reflects evolving workplace concepts based on interdisciplinary collaboration, team-oriented structures and hybrid working methods.

Acoustic Challenge
Open and flexible workplace environments require carefully balanced acoustics to support communication, concentration and diverse modes of work. The spatial concept combines transparency, adaptable zones and collaborative areas, creating acoustic challenges typical of open-plan offices and highly glazed architectural environments.

Acoustic Solution
In collaboration with INCHfurniture, an interior concept was developed based on flexible spatial zoning using modular furniture and movable elements. STREAMER pro acoustic curtains play a central role within these zones, both functionally and visually. The textile systems reduce reverberation and improve speech intelligibility while maintaining openness and architectural clarity. They enable differentiated environments for focused work, social interaction, creative exchange and moments of retreat. The translucent acoustic curtains STREAMER pro preserve the flow of natural daylight, maintaining bright and open spaces while improving acoustic comfort. The textiles are also flame-retardant, fulfilling stringent safety standards required for public buildings.

Application

• translucent acoustic textile STREAMER pro
• developed for open-plan office environments
• allows natural daylight to enter the space
• flame-retardant according to international safety standards
• integrated into flexible workplace zones
• suitable for glass walls and reflective surfaces
• supports acoustic comfort and speech intelligibility
• improves room acoustics without visually impacting architectural design

Architectural Impact
The FRITZ building demonstrates how architecture, interior design and textile acoustics can support new ways of working. The project creates an adaptable and inspiring workplace environment aligned with contemporary organisational culture.

Textile acoustic solutions by Annette Douglas Textiles enhance room acoustics, meet flame-retardant safety standards, and preserve architectural transparency and design intent.
