This thesis condenses open public space on an urban site in order to create an animated environment for public use. Maximizing use of an open lot in Sao Paulo, Brazil, an elevated concrete plate layers the site into a covered plaza below with sport and recreation program above. By lifting a programmable ground surface above street level, the project maintains the ground plane as an extension of the urban surroundings. The underside of the elevated plate becomes a horizontal elevation, or sixth façade, which is the new public interface of the project. Essentially a double-sided surface that is formally manipulated, the elevated structure both defines and unifies the two zones, mediating between them while creating different conditions and atmospheres, each with their own potential to invite public activity.
