-1, +1 project is a search for an architecture for migrant corporations. migrant corporations are constantly on the move in cities like Istanbul, especially when unstable economic and political conditions are present.as they are on the move media corporations stay anonymous in the city requiring buildings underground, insignificant large boxes.since Galatasaray’s stadium is demolished this year in Istanbul and left a 250 x 250m hole right in the middle of the highly congested city centre, I bring together 10 media groups that are in joint venture at international and national scale: sharing the -1 infrastructure (TV and Film production spaces) +1, more arbitrary configured office spaces sit above the -1 level, letting the sandwiched completely free public space for the city, right next to the main highway connected Europe to Asia where 4 million people pass by in a normal day.corporations can build in our cities such public spaces, in this case such a park type that can not be afforded by the political power in the city.
