The great masters of architecture interpreted their historical moment to solve specific problems. Today, we face the challenge of urban densification, inspired by Le Corbusier and his Unité d'Habitation in Marseille, which proposed a self-sufficient city in harmony with its environment. Our proposal advocates for sustainable, accessible, and friendly cities, integrating advanced technology, vertical gardens, green spaces, and renewable energies, promoting social inclusion and environmental protection. The current challenge is to build sustainable and livable cities for future generations, inspired by utopian visions that became reality.
