This project involved artistic design of the inner side of the facade on the 12th and 13th floor levels of the BIG company headquarters by Heimo Zobernig. The artist placed floor-to-ceiling high letters, printed as dot matrixes on a transparent separating wall, covering the window openings and radiators. The inscription TRANSPARENTOPAKESBUCHSTABENWANDDESIGN (transparent-opaque-letter-wall-design) describes the intent of the design.
