Co-curated by Melodie Leung, Senior Associate at Zaha Hadid Architects and the Museum of Architecture as part of the London Festival of Architecture 2019. Last year’s theme unpacked the notion of crossing into the unknown in design, architecture, art and science, discussing the boundaries and cultural borders created and traversed through drawing and communication, memory and imagination and collaboration. In forging a new and previously unknown horizon of possibilities, how can we create relevant means of communication and ways of envisioning boundaries which are productive rather than limiting? How does memory affect the ability to respond to an unknown future? How can new strategies be fostered within the built environment when designing across scales, cultures and differences? We ran a roundtable workshop before the main conference with Anne Beate Hovind on the topic of Cathedral Thinking. This was an invite only event for 20 leading women in the visual arts, architecture and design. The conference was supported by Finsa UK.
