3D printed rooftop homes explore adaptable urban living at venice biennale

Tiny Penthouses: adaptive Architecture by Hedwig Heinsman

Tiny Penthouses is an ongoing art and architecture project by Hedwig Heinsman that investigates how recycled materials and additive manufacturing can generate adaptable forms of housing. Presented at the 19th International Architecture Exhibition – La Biennale di Venezia, curated by Carlo Ratti, the project remains on view until November 23rd, 2025.

Developed as a prototype for compact, 3D printed rooftop homes, Tiny Penthouses proposes a model for urban densification through reuse and circularity. Each unit is fabricated from recycled materials, including sawdust and consumer plastics, which can be shredded and reprinted into new configurations. This process enables buildings to evolve over time in response to changing social and spatial needs, positioning architecture as a renewable and regenerative practice. The exhibition includes scale models, facade sections, and full-size mock-ups that demonstrate the spatial and material logic of the design. The pieces operate as both architectural research and sculptural installation, emphasizing light, texture, and structural geometry. The project frames architecture as a temporal medium, something that can adapt, transform, and return to material origin without loss of value.

Tiny Penthouses also examines underused urban sites as potential host locations for new housing typologies. One proposal envisions student residences installed within the truck lift of Amsterdam’s Stedelijk Museum, testing how overlooked spaces can accommodate small-scale, flexible living environments.

The project builds on architect Hedwig Heinsman’s broader exploration of circular construction. As co-founder of Aectual, a platform specializing in large-scale 3D printed architecture made from recyclable materials, and former co-founder of DUS Architects, she has developed multiple structures designed for disassembly and reprinting. These precedents inform Tiny Penthouses as a continuation of material research and sustainable design methodology. Following its presentation in Venice, Tiny Penthouses is set to tour cultural institutions and European cities through 2026, contributing to the ongoing discourse on adaptable architecture and circular urban growth.
