RHUBARB Installation by Atelier DARN: A Spectator-Driven Symphony of Sustainable Architecture

Located in the historic courtyard of the 18th-century Hôtel d’Aurès in Montpellier, France, the RHUBARB Installation by Atelier DARN is a groundbreaking example of temporary, interactive architecture. Completed in 2024, this 70 m² installation was celebrated for its innovative blend of sustainable design, audience participation, and kinetic art, earning the Public Prize at the Festival des Architectures Vives (FAV 2024).

An Interactive Celebration of the Audience

RHUBARB transforms the traditional relationship between art and spectatorship. Inspired by the Olympics and the concept of rhythm, the installation positions the audience as the central component of the experience. Visitors’ movements: walking, touching, or brushing against the 3D-printed components, generate dynamic sound and light interactions, making participants an integral part of the art itself. In essence, while the audience becomes the artwork, the pavilion acts as a reflective observer, amplifying every motion and creating a unique, immersive encounter.

The installation’s name, “Rhubarb,” cleverly references the subtle, ambient background noise on a film set, emphasizing the importance of collective presence. Just as background sound completes a scene, the spectators complete the RHUBARB experience, highlighting the crucial role of audience engagement in art and architecture.

Sustainable Materials and 3D Printing Innovation

A key feature of RHUBARB is its commitment to eco-conscious architecture. The installation is composed of 1,000 modular pieces, each varying in size and color to reflect the vibrant tones of Montpellier and the courtyard. Every component is 3D-printed using sustainable materials, including:

• Handcrafted PET filament from recycled household PET bottles
• Ultrafuse®️ rPET industrial filament by BASF Forward AM, derived from post-industrial PET waste
• Plant-based miscanthus material by NOVINOV, fully biodegradable

By combining these materials, Atelier DARN demonstrates how temporary installations can pioneer sustainable practices while maintaining aesthetic and functional innovation.

Design, Rhythm, and Kinetic Interaction

RHUBARB’s design draws inspiration from the rhythmic energy of the Olympics, where spectators remain a constant presence across changing events, teams, and themes. The pavilion incorporates sound sculpture elements, converting visitor interactions into a living symphony of audio experiences. This interactivity encourages playful engagement, turning gestures into wind, sound, and movement that enliven the installation.

The colorful, curved forms invite visitors to step inside, placing themselves at the center of the art. This design strategy not only stimulates collective imagination but also emphasizes inclusivity and human diversity, making RHUBARB accessible and engaging for all age groups.

Collaborative Innovation in Architecture

The creation of RHUBARB exemplifies a fusion of artisanal craftsmanship and industrial innovation. The collaborative effort, led by architects Peker Ayan, Simay Cag, and landscape architect Bilge Kobak, leverages global expertise to deliver award-winning, sustainable design solutions. Through this project, Atelier DARN highlights the transformative potential of interactive installations, showing how temporary architecture can leave a lasting cultural and environmental impact.

Recognition and Public Engagement

RHUBARB’s ability to captivate audiences was reflected in its overwhelming public support, earning the FAV 2024 Public Prize. Its success underscores the power of participatory architecture, where community involvement and interaction are central to the artistic experience. By activating the historic courtyard and engaging a diverse audience, RHUBARB bridges the gap between architecture, performance, and environmental responsibility.
