Performative Objects & Interior

Computational, generative-parametric office design iterations with biophilic interior concept. Featuring mesmerizing jellyfish aquariums as central design elements, these spaces blend sleek furniture with immersive aquatic displays. Glass walls, vibrant LED and OLED lighting, and fluid architecture create a serene yet high-tech environment, bringing nature and innovation together for the continously changing workplace experience.

This chapter explores performative objects and interior spaces shaped by bio-inspired and bionic designs, leveraging analogue craftsmanship and AI-data-driven methodologies. By integrating 3D printing, advanced assembly, and innovative manufacturing techniques, these designs push the boundaries of functionality and aesthetics. The result is highly adaptable, efficient environments that respond to human needs and environmental conditions in real time, embodying the future of sustainable, high-performance interior architecture.
