Teahouses take different design patterns. In China, Guangdong (Cantonese) style is more prominent. A teahouse of such style is called Chalou. On the other hand, in Japan, Sukiya-Zukuri style is the most preferred for most Chashitsus. This style features wide Shoji windows with a sliding door made of wooden lattice. For flooring, the house features a tatami mat measuring approximately 4.5 tatami mats.
