A different arrangement of stage and seating in each precedent study made me think of the question of "What is performance?" As all the case studies were called Performance spaces, there is some intersection between these kind of buildings.
1. A stage in performance space
2. A constraint of plot that the performer has to follow
3. Relationship between two major groups of people: audience and performer. The relationship is an action and reaction between one other that sometime produces an 'unexpected situation'
So this redefining performance concept is to create a metaphor of the 'fundamentals of performance' and to show the relationship between audience and performer. Below is the diagram showing the list of 'fundamentals of performance', performance plan and elevation, and the experimental video.
