Nowadays, due to economic dynamics, modernity, technology, and urban sprawl, humans are suffering from “placelessness”. 21st-century built environments are diminishing the unique characters that make places noteworthy. The problem with this is that people have the desire to associate with distinctive places. Ignoring this tendency will create a type of environment where places do not matter anymore. Public spaces that serve as platforms for life are not only essential to the identity of cities but also provide venues for social-cultural activities that will attract people. This master thesis seeks to explore the basic concept of placemaking and parasitic architecture, at the same time, to integrate parasitic & modularity architecture into the new public space design in the marginal areas of Tiberio,Rimini that account to changes and flexibility in different places of the city.
