Sukiya-zukuri
is one type of Japanese residential architectural style. Suki means refined, well cultivated taste and delight in elegant pursuits and refers to enjoyment of the exquisitely performed tea ceremony.
The word originally denoted a building in which tea ceremony was done (known as a chashitsu) and was associated with ikebana flower arranging, and other Japanese traditional arts. It has come to indicate a style of designing public facilities and private homes based on tea house aesthetics.
It is characterised by a use of natural materials.
