Abstract
This paper will clarify the basic size for the vertical section of I Baha Bahi in Patan, which has excellent design and is a typical pattern of the Buddhist monastery architecture, according to actual survey results and will discuss the design dimensions for the vertical section. Buddhist monastery I Baha Bahi is a minute building which was built based on dimensional design even to details of wood carving. For the vertical section dimensions, cubit which is about 420.6mm is used as a unit, and the basic size for verticality is 5.5 cubits. Height is decided by the basic size and bisection of the basic size as well. A rectangle of 5.5 cubits high and 10 cubits wide is piled up for each story with a half cubit thick of floor between rectangles. An existing wooden framework and exterior walls of I Baha Bahi were reconstructed in the mid-17th century on the brick foundation, which was laid when the monastery was founded initially. It is considered that dimensional design was made for the vertical section by taking advantage of building dimensions one size smaller than those of a traditional unit of hat which had been used for the royal buildings.
