The second part of the Utopian Hours 2026 international city-making festival will be held in Turin on October 16 and 17. After a first chapter in Rotterdam, the festival is marking its tenth anniversary edition by returning to its hometown in Italy. The event's lineup and cultural program are designed to explore how cities can respond creatively to the social, environmental, and political challenges of the 21st century. The Utopian Hours festival has been organized since 2017 by Stratosferica, a nonprofit cultural association dedicated to producing and sharing urban knowledge through content on the evolution of cities, urban communication strategies, events, community building and placemaking.

How to visualize architectural concepts in SketchUp using D5 Lite for faster design exploration.

Inverting the conventional narrative, this story begins at the end. The day after the world's collapse. While almost the entire population struggles to survive flames and solar storms, a tiny fraction is greeted by a heavily armed guard at the entrance to the Survival Condo Project, a former missile silo in Kansas converted a few years ago into luxury apartments.

Forget, then, the hermit who stockpiles canned food in his basement or the end-times prophet. In recent years, survivalism has expanded into wealthier circles, taking root in Silicon Valley among technology executives and hedge fund managers. What could once be seen merely as an eccentricity has also become a way of thinking about the future and, for some, an investment.

Heat waves are becoming more and more frequent worldwide, prompting architects to reconsider how building envelopes are conceived and designed. The focus is no longer solely on limiting heat loss during the colder months, but also on controlling how much heat enters buildings during periods of intense solar radiation. By understanding solar shading as a design decision rather than a decorative or interior-conditioning element, it becomes part of passive energy-efficiency strategies that can contribute to thermal and visual comfort while reducing cooling demand.

In Europe, cities are confronting the challenge of adapting existing urban conditions to a changing climate and warming summers while improving access to nature, quality public spaces, and the resources of everyday routines. ReGreeneration, a Horizon Europe initiative working across nine European cities, approaches this challenge through urban renaturing at the neighborhood scale. Combining strategies for complete neighborhoods, communal spaces, and nature-based solutions for cities, the Barcelona project examines how climate adaptation is embedded within residual, peripheral spaces of daily life. As part of a series following ReGreeneration across the participating cities, this article turns to Barcelona, where the project is working in the Trinitat Nova neighborhood to explore how small, often overlooked, urban spaces contribute to broader models of regeneration.
