How do cities evolve when rebuilding is no longer an option?
At the Club House Edition in Berlin, one idea cut through every session: the future will not be newly built - it will be retrofitted.

Over two days, experts across design, mobility, sustainability and technology explored how urban spaces can shift from static structures to adaptive, learning systems. With AI increasingly acting as the nervous system of urban life, cities are moving from planning cycles to continuous upgrades.

• The future of cities is retrofit-first, not rebuild-first.
• AI is becoming the operating system of urban environments.
• If it ain’t broke, why does it needs to be fixed – you can equip buildings with a new purpose.
• Success feels different today – and sometimes it feels out of reach.
