The whole design starts with the development of a section. Its identity is defined by the stacking in vertical of big scale public spaces in contrast to the domestic scale of the spaces of the hotel located in the façade. Those big spaces intersect, deform or overlap themselves creating different relations between the public programs.
The structure is concreted as an exoskeleton in the perimeter so that columns are removed from the interior as public programs such as cinema demand. Thus, the communications core is the only structural vertical support in the interior. This core also collaborates in the absorption of horizontal loads derived from the wind pressure in the façade as frameworks connect the core to the exoskeleton. The structural core adapts its morphology to the changes in the building´s section as well as the reduction in the users flow in the upper levels. Lifts are organized accordingly to the various program groups.
Sections show how the building is divided in 5 structural and programmatic stages, starting from the receptions (one for hotel and another one for the public center) and ending with the sky lounge dome. Sections also display the double nature of the façade, being bioclimatic in the north side and habitable in the south (where solar exposure is never direct as Sao Paulo is located in the south hemisphere).
