Architecture has mixed up with other design fields. Big architectural firms design in expressing the utmost accumulation of capital and its vast influence over the traditions. This can be best seen in urban design. New inter-disciplines arise and the canvas of old historical sites is being opened up to new fields of experimentation. Today we can handle urban dynamics in animation softwares which have been developed for the use in Hollywood and other movie industries. Pioneer in digital architecture age – Marcos Novak talks about „liquid architecture“ – an architecture which blends in, weaves together, expands, syncs, contextualizes, interferes and dialogues with the city canvas. Author explains both theoretically and practically with examples of his own work and work of Zaha Hadid architects, how fluid urbanism approaches are dealt within case cities of Torino (Italy), Istanbul (Turkey) and London (UK). Can we already say that architects have a great influence on cities which evolve and are in constant developments towards the needs of modern society? Where are we heading and what are we looking for in the contemporary cities of the 21st century? Is urban planning architecture gaining a new horizon and becoming a playground for new possibilities we never thought about before?
