Marco Iannelli (born 1983) is an architect and artist based in Germany with Italian roots. After fifteen years of architectural practice, he began working as il pittore immateriale, questioning architecture as a speculative image and using AI not as an author but as a dialogue partner. His first solo exhibition, Guerilla Domus (2026), turned this into a collective ritual in a Romanesque church, where around 150 people laid their phones to rest in a coffin. The work drew national media attention and the appreciation of the Holy See’s Dicastery for Culture and Education. As a researcher at HFT Stuttgart, he explores Projective Fiction: speculative images as a form of knowledge. His leitmotif is tutto torna, everything comes back.

[extended version]
Marco Iannelli (born 1983) is an architect, BIM expert and artist based in Schwäbisch Gmünd, Germany, with roots in Molfetta, Apulia. His work moves between built space, digital planning and the speculative image, and increasingly between architecture, image and ritual.
Under the name Il Pittore Immateriale, he develops an artistic practice that questions architecture as a speculative image. He uses artificial intelligence not as an author but as a dialogue partner, keeping full control over every image. His series Guerilla Diptychon pairs real buildings with AI generated counterparts: ephemeral spaces conceived not as design proposals but as realities in their own right. Guerilla Domus (2026), his first solo exhibition, turned this approach into a collective ritual in the Johanniskirche of Schwäbisch Gmünd, combining light, performance, sacred space and around 150 phones laid to rest in a coffin. The work was selected for Time Space Existence by the European Cultural Centre in Venice, parallel to the Biennale Arte 2028.
His engagement with the image as an autonomous space reaches back to 2006. As a student under Prof. Knoll at the Institute for Representation and Design, University of Stuttgart, he built Decré, an illuminated computer aided reconstruction of the Nantes department store destroyed in the Second World War, fitted with 140 individually soldered LEDs. The model was shown in Leuchtende Bauten: Architektur der Nacht, curated by Dietrich Neumann and Marion Ackermann at the Kunstmuseum Stuttgart, and subsequently at the Netherlands Architecture Institute (NAi) in Rotterdam, today Het Nieuwe Instituut.
As a researcher at HFT Stuttgart, he explores Projective Fiction: the AI generated speculative architectural image as an epistemic mode, beyond representation and didactics, as an autonomous form of architectural thinking, regardless of whether it is ever built. Since 2025 he has been an academic staff member of the Eco-Box research project at HFT Stuttgart, a BIM based timber modular construction project focused on sustainability, developed in collaboration with Züblin.
He has been invited to give an online lecture at the Kalo Foundation near Chicago, housed in the former home and studio of the Italian American sculptor Alfonso Iannelli (1888 to 1965): who collaborated with Frank Lloyd Wright on Midway Gardens: a namesake who, like him, lived between art and architecture and whose roots also lie in southern Italy.
His architectural career spans fifteen years. Since July 2026 he has been Authorised Officer, Art Director and Head of AI at Sonnentag Architektur Factory GmbH in Schwäbisch Gmünd, where he has led BIM since 2019. In 2018 he founded 2N 2L architektur. Earlier positions include project lead for public buildings at Klaiber + Oettle (2014 to 2017), FERRARA ARCHITEKTEN AG in Basel, and Hetzel + Ortholf in Freiburg, where his career began in 2011. He is a BIM consultant for Vectorworks and has taught since 2022 in the nationwide BIM qualification programme following the standard of the German Chambers of Architects and Engineers.
He graduated from the University of Stuttgart in 2009, with internships at CHORA Architecture and Urbanism in London and as exhibition designer for the new Porsche Museum. His diploma project, Jules Verne’s Propeller Island, was named a BauNetz Campus Master in 2010.
His personal leitmotif is tutto torna: everything comes back. From Decré in 2006 to Guerilla Domus in 2026 runs a line he only recognises in hindsight.
