Architect Bruno Juričić has unveiled one of the world’s largest and most complex 3D-printed structures at the 16th Venice Architecture Biennale. Dubbed the Cloud Pergola / The Architecture of Hospitality, this massive, site-specific structure for the Croatian Pavilion features 300 kilograms of 3D-printed biodegradable plastic. The immersive cloud-like installation invites visitors to reflect on the topics of hospitality, climate change and sociability.

Bruno Juričić with Cloud Pergola

The Cloud Pergola is a contemporary take on the classic Mediterranean pergola structure, a space where “the private and public merge.” Curated and authored by Bruno Juričić in collaboration with Arup, Ai-Build and Alisa Andrašek, the innovative pavilion’s main focus is the ‘Cloud Drawing,’ a 3D-printed structure built of voxels arranged in a fluid-like mass using over 100,000 extruded elements. A “multi-agent algorithm” that was built with data on cloud formation and site-specific environmental data was used to inform the design’s lattice-like form and arrangement.

The Cloud Pergola is complemented with artwork that helps create an immersive experience. Vlatka Horvat’s wall-based work ‘To Still the Eye’ explores the “notion of horizon as a physical manifestation of distance and as a metaphor for the future, wanting to address this sense of possibility,” while artist Maja Kuzmanović’s ‘Ephemeral Garden’ is an audio installation.

“I wanted the pavilion to push the boundaries of the aesthetics, spatial and tectonic consequences of emerging paradigms of augmented intelligence at the cross-over between architecture, art, and engineering by presenting a full-scale pergola structure made using 3D robotic fabrication and automated design protocols,” said Bruno Juričić in a statement. “The Cloud Pergola was envisioned as a paradigm for what architecture should stand for in the 21st century.”

Arup and the 3D manufacturing team of Ai-Build also developed a simple assembly sequence for the Cloud Pergola, which will be put on tour after the end of the Venice Biennale. The Croatian Pavilion will be exhibited for the entire duration of the Architectural Biennale, until November 25, 2018.
