A riverside building in S shape

Sassoon, a Jew, bought a vacant lot on the north bank of Suzhou River for the use of setting up a building. It’s a plot in an irregular shape narrowing westward. The designer adjusted measures to the very condition and worked out an unique design——to shape the building as a big S. Such a design was conform to the shape of the plot, and pleased Mr. Sassoon as well——the initial of his name is S.
