Submission- set of 2 dimensional section drawings of stairs

Stair 1- This set of spiral stairs are used for going down to Louis Bourgeois's studio. The materials used here is glass. As you can see, the stairs has no handles or railings next to it. I decided not to include them because i wanted to express the feeling of "solitary"through the sense of not relying on the railings as the audience walk up and down the stairs. 

Stair 2- This set of stairs leads down to the gallery from Ai Wei Wei's Studio. The materials used in making these set of stairs are wire and cement. Through last week's tutorial, Jacky suggested to make the stairs "hang" in the air, so for the final product, i took his advice and changed it. Unlike the old set of stairs, the structure of it feels less heavy.
