Cities Connection Project was born with the aim to establish a network of cultural connections between Barcelona and other European cities with an important architectural tradition. A series of architecture exhibitions are the focus of this project that also offers other events such as conferences, meetings among universities, and the desire to create synergies among the professional architects involved. Each event, which is called "Connection", is composed of a first exhibition in Barcelona, followed by a second event in the invited city. Barcelona has become a worldwide-recognized brand, in which architecture and urbanism have played a key role.

One of the main elements of the "Barcelona Model" is
the quality of residential buildings. Currently a younger generation of architects has been able to address the issue of new housing programs responding to new social
demands and urban areas. The Connection_Export Barcelona project tracks new ways to integrate social housing and urban public space, creating new synergies
for abandoned urban real estate dating from the boom years.
