This is an office designed by architect Shigeki Maeda. In this work, Door Knob Agaho 192 is used.
Mr. Maeda said “at an early stage I had chosen which doorknobs to use.” He imagined “diffusely reflecting walls, with small elements like isolated dots.” As he imagined, they appeared like dots and don’t break the overall image. We can see the details if we come closer, but they disappear if we step back.
