ABSTRACT
This chapter focuses on the rich architectural meaning and formal possibilities inherent in juxtaposing multiple systems. Continuous juxtaposition and interaction of systems generates a three-dimensional built field, in which multiple systems jointly define overlapping zones of territory, use and circulation and jointly create closure and position wall openings, passages and transitions. The vertical zone of transition is generally marked on the facade by a change in cladding material, often emphasized by a belt course. The use of systems based on natural and regionally available building materials - both field-assembled onsite and fabricated in local factories - has been declining for several centuries. Wood assumes many different forms as it structures log, post-and-beam and stickbuilt buildings, arches, planar roofs and domes. However, the tight mutually defining bond between a people, its culture of building, primary building typology and chosen combination of architectural systems has loosened.
