At the smallest scale, within shortest time, and with lowest budget, 'Share City' carries the dreams of 102 households for their living space. In a modern city, public housing must combine public accessibility with the most basic necessities of life. This project integrates the outdoor space in the ground to third floor as part of the urban public streets. From the fourth to the ninth floors, it transforms into a high-quality living environment where each household enjoys their own space. Simultaneously, it fosters a sense of community by sharing the public spaces within the residential area.
