The empty middle space in the multiple road junction of Trinitat, in Barcelona, is used to incorporate a mixed-use building. 
The construction is developed between two underground stations, creating a comunication circuit that includes mall, cultural spaces, restaurants and community services. 
 
The circular conception includes tangentially access to the interesting points between the different levels of the roads above, into and below. The building is developed between different heights of roads and rails, using the empty space between differents floors to get joined the not-used and forgotten locations. The project is like a huge connection nexus, structuring the road residual areas.
