Production Technology
The gold leaf tiles are crafted using the UNESCO-listed Hand-Applied Gold Leaf technique. Each 200mm square porcelain tile features textured surfaces enhanced by meticulously applied gold leaf, creating depth and richness. The lighting design is strategically planned to maximize gold’s reflective qualities, enveloping the space in a serene, ethereal glow.
Design Challenge
The greatest challenge was crafting a space that maximizes the texture of gold leaf while maintaining a refined and immersive ambiance. Detailed studies of light angles and reflectivity were conducted to create a lighting design that showcases gold at its most mesmerizing.
Research
English: Type of Research: Interior design study Objective: Exploring the potential of traditional craftsmanship in spatial design Methodology: Analysis of gold leaf’s light reflection properties, lighting simulations Data Collection: Reflectivity measurements, visitor sensory evaluations Results: Creation of an immersive design using gold leaf Impact: Introducing new applications for Japanese traditional crafts
Inspiration
English: The core inspiration of this project is to transform the beauty of Kanazawa gold leaf, a symbol of Kaga culture, into a contemporary spatial experience. The golden enclosure is designed to immerse visitors in the profound artistry of traditional craftsmanship. The interplay of gold's sheen and shadows evolves with time, creating a mesmerizing atmosphere.
Project Duration
The project is located in Hakusan, Ishikawa, Japan, and was completed in April 2021.
Operation Flow
The restroom offers visitors an immersive experience enveloped in golden radiance. Indirect lighting dynamically alters the expression of the gold leaf, transforming the space into a living artwork of light and shadow. Users feel as if they have stepped into an art installation, elevating a routine activity into an extraordinary encounter.
