The Shako-ken tea-house is a typical example of the informal 'mountain hermitage' style of sukiya tea-house construction. l In this chapter the extemal architecture of the Shoko-ken is discussed in terms of its structure, roof forms, components-materials and details. Some aspects of the architecture are standard features of most sukiya tea-house designs. Other aspects compare closely with Sen no Rikyii's or Furuta Oribe's examples of tea-house architecture. Further aspects are unique to the Shako-ken. In this discussion aspects of the external architecture are localized and treated individually.
