This is an entry for an idea competition for reinventing parking garage in 2014. Site is specified near Hudson Yard in New York City. The idea behind the community actuator is to re-imagine parking structure from a private enterprise into a multivalent public service provider. By using programmable robotic parking system, the garage not only efficiently stores cars, but also contains much needed urban public spaces that are activated by the infrastructure store within the structure. The idea is to recast a garage as an urban infrastructure as a flexible and adaptable purveyor of public services.
