Exhibition and art installation designs in the sister gallery of Prostora in Prague's Vinohrady. The original telephone exchange hall was only cleaned and all traces of the building's history were left intact. Individual exhibition installations always work with this building essence and also use materials that were stored during the partial reconstruction. Instead of exhibition plinths, the original wire glass from the gallery's windows is used, and traces of former equipment are included in the hanging works. The exhibition concept is created in close collaboration with individual artists, and the works and space are connected into meaningful wholes. The site-specific installation completes the natural daylight and the lighting of the hall's structural elements with added lighting fixtures on tripods.
