This section is featured in the Sofia Paper Art Fest programme periodically due to its specificity and connection with architecture and design offices. The largest presentation of this section was in 2011, when architects and designers were presented in an exposition with a discussion on the role of paper in contemporary architecture and design.

Global names such as Shigeru Ban, Zaha Hadid, Sir Norman Foster, Renzo Piano, Frank Gehry and Fumihiko Maki, winners of the Pritzker Prize for outstanding achievement, have been represented. The presentation of these big names with certain projects that have contributed to the development of world architecture and design is linked to the medium of paper. The most prominent representative is the Japanese architect Shigeru Ban with his paper architecture. He has made outstanding contributions to the creation of temporary architectural structures in disaster situations.

Various editions of the festival have featured some of these projects in lectures and presentations, which has contributed to enriching the knowledge of many young future artists. Thanks to this section, interest has been aroused in new technologies for the construction of temporary architecture and works for the urban environment.
