“Known by Sight” examines an increasingly frequent situation in the contemporary urban context: apartment buildings with opposite windows way too close. Views that don’t show the city or the landscape, but someone else’s life nearby. Neighbors who don’t formally know each other but can make long descriptions about each other’s daily habits. This work was developed through the contact with dwellers from more than 50 apartments, chosen by chance, in narrow streets from Porto Alegre – Brazil. The idea was to counterpoint views and points of view, always visiting apartments on both sides of the street. The dwellers testimonies were collected in informal chats and complement the images, revealing these unique relationships established in the city.
