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

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.

Practically every history book records 1961 as the year man first reached space, an achievement that placed the Soviet Union at the center of the space race. What not everyone knows is that Yuri Gagarin's journey began in a seemingly unlikely place, more precisely in Kazakhstan. From the Baikonur Cosmodrome, Gagarin set off beyond Earth, inaugurating not only a new era of space exploration but also a history of technology and ambition that would transform this landscape.

As cities change, so do our expectations of them. People are asking for more caring spaces: public places open to all ages and genders, nature within reach of every social class, and settings that foster connection. Few design intentions hold these together as well as spaces for children. This selection of unbuilt projects submitted by ArchDaily readers showcases different approaches to care-based architecture. Schools, daycare centers, a library, a youth center, and a new model for orphanages take on the mission of providing a safe and stimulating environment for children at every stage of their development. Not yet built but carefully designed, these proposals offer a glimpse into spaces for play, learning, and calm that fuel creativity in design for people of all ages.
