We have made this 90m long, 4 storey high installation to provoke a public conversation. It invites you to think about how this city makes you feel, and to question how the outsides of buildings affect your brain, your body, and your behaviour. The structure is made of 1,428 individually designed steel tiles, inscribed with the creativity and insights of citizens, scientists, and designers. They tell the story of how so many parts of so many cities became boring and soulless, and the impact this has on our health and society. The wall also features 400 buildings from 38 countries made by 110 of the world’s best designers showing what interesting, joyful, human buildings can look like. These snapshots from around the world are here to give you hope and inspiration. They sit alongside the work of 9 creative community projects, who have made beautiful, inventive, challenging images that convey how the buildings in Seoul make people feel and how they would like to see them evolve. At its centre, the Wall twists audaciously, mixing ideas like a giant bibimbap. It forms a gateway, drawing people into the debate. Here you’ll find a manifesto for making the outsides of buildings radically more human, with practical ideas about what we can do and ways to change our thinking. This wall has been made for everyone. It speaks to each of us as citizens and passers-by. It invites us all to dream more and demand better.
