From September 6 to October 15, 2025, the Aedes Architecture Forum in Berlin will host an exhibition on the Finnish architectural firm Helin & Co. The show aims to examine the firm's role in shaping Helsinki over the past two decades. Titled Heart and Horizon, it reflects the practice's approach of combining the human scale ("Heart") with an engagement with urban space along the waterfront ("Horizon"). A central focus is placed on three projects that have been fundamental to Helsinki's transformation: the Kamppi Centre, a networked urban quarter with mobility hubs, cultural and residential areas; the Kalasatama Centre, a new district on the former harbour that combines urban density with views of the sea; and the Sello District Centre in Espoo, a multifunctional complex with a library, music school and concert hall.

In today's world, learning is no longer confined to classrooms or defined by formal education alone, it happens everywhere, in many forms. From music halls and sensory libraries to neurodiversity training centers and public schools reimagined, the spaces that support learning are becoming just as varied as the ways we learn. This selection of unbuilt educational projects submitted by the ArchDaily community reflects that shift, exploring how architecture can embrace difference, nurture curiosity, and create environments that support a broad spectrum of cognitive, emotional, and social needs.
