http://www.leeyangyang.com/the-pinwheel/The urban strategy seeks to make aware of the distinctive qualities of the city of Perth, in this sense the Perth city grid and its anomalies. Irregularity of the grid such as unexpected streets end up in buildings rather than a continuous line. The pinwheel plan is formulated due to the unaligned meeting point between Queen Street and Wolfe Lane. As the threshold, the pinwheel in this manner serves to rotate the forces not just two-dimensionally, but also three-dimensionally upwards and downwards. The facade is formed in recognition of linesight termination and dual old and new quality of Perth, serving to bridge the old and new in a gradual manner.
