One categories of exposure include sound and scents – types of sensory information that are often attempted to be reduced, minimalized or eliminated in interaction between spaces in our built environment. Hierarchical relationships in exposure introduce issues of publicness, privacy, control and power as exposure reveals the internal events of a space into a larger external realm. The common occurrence of visual exposure is using large windows, balconies, landings and mezzanines to allow the events of one space to be visually experienced by an adjacent space but without physical connection. The presentation of a space visually to its surroundings or the allowance of sound or smell transmission is a parallel factor in architectural quality and success. Spaces that are exposed allow themselves to be more public and reduce the barriers of control in order to gain some benefit or need for the activities contained within that space.
