Chashitsu - Japanese tea rooms - are known for their sparse composure. Lined with tatami mats and edged by gardens, these ceremonial spaces are testaments to the enduring elegance of simplicity and serenity yet are imbued with a touch of ancient mystery. Rhomboid stone tile set in hexagons creates a tranquil wall befitting a Zen-like space. However, carefully placed lighting divulges the secrets of the chiseled surface, exposing sharp contrasts and emphasizing dimension. The choice is yours.
