Ratnakar & Sons stands as a landmark in contemporary jewellery retail architecture, distinguished by a parametric metal facade crafted by Soga Design Studio that merges computational precision with luxurious visual storytelling. The facade’s rhythmic modular panels, featuring protruding geometric blocks and integrated illuminated edges, create exceptional three-dimensional depth and a dynamic play of light and shadow that shifts throughout the day. Engineered through advanced Rhino–Grasshopper workflows, each panel is fabricated from a custom bronze–aluminium alloy with concealed fixings and seamless dry mounting, ensuring durability, weather resilience, and a refined finish. Beyond its sculptural aesthetics, the facade offers passive shading benefits, energy-efficient LED illumination for nighttime brand visibility, and a modular system that supports easy maintenance and long-term sustainability. Inspired by jewellery design motifs, the architectural language aligns closely with the brand’s identity, transforming the showroom into a premium destination and a striking urban landmark. This project reflects Soga Design Studio’s signature ability to unite parametric innovation, material engineering, and luxury retail branding into a cohesive, high-performance facade solution.
