There is no fixed landscape from inside the Vollard Suite building. At the touch of a button, the occupants of each of the 11 apartments have access to a 360 ° panoramic viewover the entire city skyline. Concept building, the Moro construction company, in Curitiba, is the only revolving building in the world. The implementation of the project, signed by the architects Bruno de Franco, technical director of Moro, and Sérgio Silka, required the involvement of a large number of professionals from various areas, in complex planning and testing work that lasted for more than a year. Having achieved the perfect balance between the mechanical systems for the rotation of the mobile part of the building and the architectural design, the team found in PVC frames the best technical solution for the facade.
