Some buildings are never built — yet they still shape the future. A 360-metre tower of colour, curves and ambition — imagined in 1908, impossible then and strangely relevant today. Before skylines became dominated by glass, steel and repetition, Gaudí imagined something closer to a living organism. A city landmark with emotion embedded into its structure. Gaudí’s unrealised Hotel Attraction reminds us that architecture is not only about what gets constructed but what societies choose to imagine, fund and preserve. It challenges a familiar pattern in city-making. The tendency to optimise for efficiency while quietly eliminating wonder. A century later, AI allows us to glimpse that “future that never happened”. AI now gives us new tools to revisit these lost possibilities. Not as nostalgia but as a conversation between heritage, technology and the cities we have yet to create. AI-generated visualisation is not replacing architecture. It is reopening questions. The lesson is not that every radical idea should be built. It is that progress requires the courage to protect ideas that initially appear impossible. Perhaps the greatest constraint on tomorrow’s cities has been technology. What ideas did we dismiss too early? What futures did we value-engineer away? Architecture is not just the memory of what we created. It has been imagination. It is: we were brave enough to imagine. The next generation of cities may depend less on building bigger... and more on thinking differently.
