In order to resolve a zone of transition between the perimeter blocks of the Barcelona ‘Ensanche’ and the towers and slabs of the sixties and seventies, a great unifying gesture is proposed – one which is both monumental in scale and openly generous with the city. The plan and profile of this 300-meter-long volume occupying three blocks are broken up with the objective of lightening their impact; the rhythm of its innumerable openings expresses the urban character on the facade to the Diagonal and distinguishes the assigned functions of the program on the interior facades. Seemingly molded in the hands of a sculptor and constructed with noble materials such as Roman travertine, African granite, steel and glass, the building mass is balanced in order to distance itself from the usual commercial boxes, avoiding the banalization of its image.
