As the solstice marks the shortest day of the year in the Northern Hemisphere, it also draws attention to something architecture has long negotiated but often overlooked: time. Beyond form or function, buildings and spaces are continuously shaped by cycles of light and darkness, seasonal shifts, and environmental rhythms that affect how they are inhabited.

In recent years, a growing number of architectural projects have begun to work explicitly with these cycles. Rather than designing spaces to function in a single, fixed way, architects are creating environments that change throughout the day, across seasons, or in response to natural phenomena such as the sun's path, lunar phases, wind patterns, or circadian rhythms. These projects operate in dialogue with time, appearing, transforming, and activating differently depending on environmental conditions.

Europe in the 1960s was an incubator for emerging provocative architecture radicals who defied traditional architecture dogma in favor of counterculture that transcended time and space. Coop Himmelb(l)au, a Vienna-based faction of this movement, questioned the clean lines, rigidity, and literal nature of modernist architects of the time. While the firm is known for their rebellious spirit and aggressive forms that are generated through state-of-the-art 3D software and technologies, it’s important to acknowledge the work that the firm did shortly after their inception in 1968, and how their early oeuvre still relentlessly breaks the status quo of modern-day practice and academic discourse.

Since 2010, the Danish architects from Schønherr have been developing a series of large-scale urban interventions for the Aarhus Festival, the largest cultural festival in Denmark. These temporary projects have transformed the streets and parks into extraordinary public spaces, changing the natural topography of the city to attract citizens and bring them together.

We present their last four projects: "The Forest" (2010), "The City Park" (2012), "The Plaza" (2014) and "Bishops Square" (to be completed this 2016).
