I think there is a problem with the shape. The shape of the building should be tall and thin, not short and fat. The height and number of floors are correct, but the radius of the circle at the bottom should not be 100 meters.
The next step should be to find more multiple points on the curve and connect them with interpolation curve in order to form the weaving structure of the facade.
Then the difficult part I think is how to transform the shape and find a reasonable control line of the facade, which may be related to a function.
