Franz-Josefs-Kai 51

1010 Vienna (AT)

The study envisages a conversion of the building used as an office on Franz-Josefs-Kai into a residential building with 8700 m² GFA on nine upper floors and one lower floor. The structural shell of the reinforced concrete structure will be preserved for reasons of sustainability as well as historical reference. It is even more emphasised by the use of exclusively room-high glass elements as the building shell.
