As one of the most historic places in the city, Parque dom Pedro has been through a long history as a place for bathing, a park, and a place full of squatters. For a long time, it has been abandoned and overlooked because of flood. In order to reactive such a potential area in the metropolis, and to response to the housing shortage in Sao Paulo, we propose that Parque dom Pedro will be transformed to an interface bridging the two sides of the Tamaduatei River. A series of pockets of outdoor places are defined as parks, school playground, and street market, which are all linked by a continuous, linear system which contains housing, school, retails and a skateboard park underneath.
