Stairs leading to above ground: Represent coins, whihc reflects idea of consumerism and money. THe path is not linear and represents the confusing nature that is the path of consumerism, where money is hard to obtain and there is a great struggle.
Simple stairs leading from 'minimal space' to 'minimal light'. The stairs are not all the same size and length, so one would struggle to walk through them, therefore they would really feel enclosed in the space.
Sphere stairs: act to juxtapose against the minimal space inside. Sphere opens up to a wide room, and then shrinks, so when one enters they feel enclosed in the minimal space. Also acts as a fulcrum to see saw.
