Calatrava Defying gravity in an obvious way
Kahn Displaying in horizontal and vertical section simultaneously

For this one, the lower part if the unfold of one piece of material, like cut off the central part of it and make it . To outstand the gravity idea of the upper part, I use the significant contrast between the thickness of these two parts.

Calatrava: unconfined boundaries, permeable, porous sculptures

The upper drawing shows much more detail than the lower one. Because the side which sculpture facing is exposed, while the oppsing side is block. So the new concept is "enclosed".

  Kahn:Powerful presence leading to a pinnacle point

The basement part is organised by intersected 5 piece  of thin concret. The upper part is completely holded by the basement. And the image drags people's attention to the right hand side which the material is about to touch while not. This is presence leading to a pinnacle point.
