A sales office (cancelled)，unfortunately, due to cost reasons, the client finally cut it off and did not start the construction. The drawings were originally completed. The special feature of this building is the peculiar outline of the roof, which is a vertical line that is transformed into a horizontal line through translation and rotation, and the swept path merges into the final curved roof.
At the same time, the facade also has an effect similar to piano keys, which is simulated by different rods, and the bottom contour is an outline cut by a trigonometric function. It is actually very interesting, but it was eventually cancelled by the client due to cost and other reasons.
