The complex is located in the trading area “zona franca” of Barcelona and comprises six virtual volumes, each with a restricted height, a position on plan with views directly out onto the main road and each governed by a set of rules. Just as the material and technological limitations in gothic or Mediterranean villages produced a repetition of form, so the design parameters produce consistency between the buildings, creating a continuous and differentiated fabric of buildings rather than relying on the qualities of individual buildings. Since only 50% of the footprint may touch the ground and at least 25% must be roofed by the building, ground is liberated tor public use, producing an urban fabric in which sheltered public spaces and buildings are tightly Integrated. The buildings themselves are capable of hosting a wide variety of workspace types forming a new typology of commercial space which both gives developers the freedom to change the floorplate quality as tenants become engaged.
