The 360° Inflatable Parasite project reimagines an abandoned water tower located in Scalo Ferroviario Porta Romana, Milan, Italy, into a lively residential space. The design addresses urban development challenges by creating a functional living environment that respects the history of the structure. The core concept integrates two tiny houses within the tower, offering an efficient housing solution that reduces the demand for new construction.

Residential Integration

The design includes two tiny houses, with one placed inside the tower and the other situated nearby. Each unit occupies a compact space, limited to 15 m², and incorporates necessary amenities such as a kitchen, washroom, storage, and combined living and bedroom areas. This thoughtful arrangement makes the most of limited space while ensuring comfort and usability.

Sustainable Features

Sustainability is a key focus of the project. The existing water tank provides a source of water for the two tiny houses. A rainwater collection system further supports its self-sufficiency. The design includes circulation paths that allow easy movement both within and around the tower, fostering a connection between the residents and the vibrant urban environment outside.

Material Approach

The inflatable structures that wrap around the tower are made from ethylene tetrafluoroethylene (ETFE). This material is known for being durable, lightweight, and highly transparent. It enhances energy efficiency by allowing more UV light inside while providing better insulation than traditional materials. These inflated volumes create adaptable living spaces that respond to different weather conditions, enriching the experience for those living there.

Community Engagement

A notable aspect of the design is the roof garden and viewing platform on top of the water tank. This feature not only improves the building's appearance but also serves as a shared space where residents can interact and enjoy views of their surroundings. The inclusion of communal areas reflects a modern understanding of urban living, where social connections are as important as private comfort.

The project creates a blend of past and present, turning a forgotten structure into a place that invites people in. With its focus on utility, sustainability, and community, it illustrates a thoughtful approach to urban living that respects its historical context while adapting to contemporary needs.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
