Sukiya-zukuri is one type of Japanese residential architectural style. Suki (ateji: 数寄 or 数奇) means refined, well cultivated taste and delight in elegant pursuits, and refers to enjoyment of the exquisitely performed tea ceremony. The word originally meant a small structure for the Japanese tea ceremony (known as a chashitsu) and was associated with ikebana and other Japanese traditional arts. It has come to indicate a style of designing public facilities and private homes based on tea house aesthetics. Historically and by tradition, sukiya-zukuri is characterised by a use of natural materials, especially wood. In contemporary architecture, its formal and spatial concepts are kept alive in modern materials such as steel, glass and concrete. In 1587, Toyotomi Hideyoshi (1536–98) employed the tea master Sen no Rikyū as his advisor on aesthetic matters. In the compound of Hideyoshi's imposing Jurakudai castle in Kyoto Rikyū designed an eighteen mat building known as the Coloured Shoin which was thought to be the first example of sukiya-zukuri architecture. The style developed during the rest of the Azuchi-Momoyama period (1568–1600) and was characterised by small rooms of usually four and a half tatami, or even less, that had a tokonoma and shelves. These buildings were normally entered through a garden often by means of an indirect curved or diagonal path that would not allow an instant view of the teahouse. Sukiya-zukuri architecture incorporates tea house aesthetics and encompasses all sorts of building types including private dwellings, villas, restaurants and inns. One of the best known examples is the Katsura Detached Palace in Kyoto. In the Edo period (1600–1868) sukiya-zukuri became popular among townspeople, and the majority of houses came to be built in this style. In the Azuchi-Momoyama period not only sukiya style but the contrasting shoin-zukuri (書院造) of residences of the warrior class developed. While sukiya was a small space, simple and austere, shoin-zukuri style was that of large, magnificent reception areas, the setting for the pomp and ceremony of the feudal lords.
