It's offered to us the opportunity to represent the elusive nature of the contemporary city which, reinventing itself throught a continuous process, appears without shape and crossed by an elusive fluency. We have thought of a dynamic architecture with shaded borders able to dissolve itself in the environment in order to answer to unexpected changes of the contemporary city; this (architecture) will succeed to overcome the division conception to the space that receive it. A vivacious continuous internal course will create a succession of spaces for art and architecture on the water plane and for relaxation on the first floor; these (spaces) will be always able to create new scenarios of mutations like the eddies in the regular flow of Thames river.
