Japanese design has always been admired for its high level of craft, precision, sensibility and simplicity. A serenity that inspired the contemporary design of a living room overlooking a guest room. The library that connects both spaces presents a combination of hornbeam wood and copper details. The subtle use of these two materials, that are natural and hardly treated before use, allows spreading purity, clarity and serenity to the living spaces. Because the act of subtle purity can make things simple and stimulate people’s imagination. In fact, this is the very virtue of Japanese spirit of beauty.
