320 local & international practitioners, public representatives, end-users, activists, managers, entrepreneurs, educators, experts, students and policy makers have been invited to participate. The objective is to bring a diverse group together; people with experience of the issues, people who can bring fresh insight and anyone who is interested in change.

On day one of the conference groups of people gather in 16 remarkable Hidden Rooms across the city to work on one of 16 city challenges or issues. An international practitioner will present a related project or body of work to each group to provide inspiration. A Dublin practitioner will facilitate. Each room will be hosted by a Dublin City issue owner. Each issue will be set in context locally through a scenario in 16 years time (2030). The intended outcome is a route map for addressing the issues, ideally framed as a pilot project proposal.

On day two all participants will gather in City Hall to present their proposals. We are aiming for credible proposals that emerge from the process which could help inform policy or be actioned as pilot projects by DCC and partners in 2015.
