The prime location of the site on the Besòs coastline prompted a reconsideration of the layout of the apartments and the position of the vertical communication shafts. Three stairwells are planned as an alternative to a system with access via a walkway, which would minimise the relationship between the dwellings and the river, with the clear intention of generating an active frontage overlooking the Besòs river park. The building adapts to regulatory heights, and all the dwellings have rooms overlooking the river; in addition to ensuring visual quality, this helps to reduce the need for cooling without the need for additional sunshading in the atriums.
