The graduation project of Interior building Cities focuses on the renovation of national bank of Belgium. The current bank building is the result of a massive reconstruction project that transformed and rescaled this piece of city into an imposing, yet ultimately alienating urban environment. Due to the relocation of some of its functions and the restructuring of the bank, the National Bank decided to redefine itself. Beyond providing the bank with workspace offices, it is envisaged as a more open, permeable environment. My project focuses on a passage through the bank and to redefine the boundaries between bank and public.
