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

With 1999 transbanana transformed into

and a bit later it got a partner, 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.
