Concrete

A new building is about to be done, the metal structure and the concrete as its bones.
You can imagine the organs where they would be, and you can almost see the skin which is not there yet.Like a human body a building starts to breath.People start to live or work inside, like blood cells.
Some buildings don't decide their position.They take the free space available.
How will a building cast its shadow on the ground?
Do architect think about that?I guess the would answer yes.
