Transbanana was set up in Graz (Austria) in 1996 by Margarethe Mueller, Bernd Vlay and Paul Rajakovics.

With 1999 transbanana transformed into

Till 2008 transbanana worked together with Walter Kletzl.

Transbanana is housed in the Palmers building at the Hauptplatz in Graz and at an old factory building for producing Alps-milk in Vienna. Nevertheless the working space of transbanana is everywhere.

Transbanana produces designs, concepts and studies for spaces, mainly in the fields of architecture and urbanism.
