The project series documents "Breathing Architecture," an installation initially presented at the Galleria Federico Luger in Milan, in 2012. The installation consists of a square shaped sheet of plaster placed on a wall giving the impression that a portion of the gallery wall has been lifted to create an opening in order to allow it to breathe. This installation has similarities to Pettena's earlier project "Grass Architecture" for Trigon '72 and "Parete "Branchia"" in 1999. "[...] here the work, which on this occasion takes up the whole of a wall all by itself, has more the significance of a gesture, of a sculpture that retains memories of architecture, and at the same time of the school of conceptual art in which Pettena was also formed."  This installation was also later presented at the UMOCA in Salt Lake City, Utah, in 2013, and at the exhibition "Architetture Naturali/Gianni Pettena" at the Kunst Meran/Merano Arte, in Meran, in 2017.
The project series contains photographs of the first and the second editions of the installation and a drawing. It also contains photographs of the 2017 edition that also shows Pettena's other installation "Paper/Midwestern Ocean" presented in the same exhibition.
