This design proposal provides“healthness” facilities for the Philadelphia community, promoting physical, intellectual, as well as social health for its members. Water is used as a variable agent that either unifies or separates program spaces throughout the project. The collection, dispersion, or absence of water are events that either sharpen or blur the boundaries between zones that are used for different activities. Such dynamics are made possible by the assignment onto the site of several surface textures of different permeabilities to water.
