-If they are on a grid they are not true pilotis.
-You have too many things: pilotis, grid shaping, column carving & variable diameters
- keep one grid and move columns off the grid.
-Change & diameter + carving should be most important. Enlarging diameter makes it more cellular and gives you rooms. Carving gives you view and wayfinding. How do you make rooms and walls?
-Make big poche columns to absorb rooms
-Look at the Laurentian Library stair(Michelangelo) to see how columns can manipulate perspective.
-Make columns and cuts bigger.
