The Ibirapuera Auditorium (Portuguese: Auditório Ibirapuera) is a building conceived by Oscar Niemeyer for the presentation of musical spectacles, situated in Ibirapuera Park in São Paulo.
The auditorium completes the group of buildings in Ibirapuera park, as designed originally by the architect in the 1950s. Compared to the original proposal it is lacking only the access square that would separate it from the Oca, which would serve as the main entrance to the park. At the 2008 Latin Grammy Awards the Brazilian Field awards were presented at the Ibirapuera Auditorium. In December of the same year, the Ibirapuera Auditorium was the host of the final fashion show of America's Next Top Model, Cycle 12.
The building possesses volumetric simplicity, composed of a single block that in plan has the form of a trapezoid and, in section, the form of a triangle. As well as the other buildings in the park such as the Oca dome, and a great part of the architect's work, the auditorium is composed of reinforced concrete painted white. The unique form and spatial massing sets it apart from other auditoriums for concerts since the conception of the Paris Opera in the 19th century. It is composed of a separation of three parts, which makes a sequence of foyer, audience, stage from the exterior to the interior.
On the first floor is a foyer leading to the stage and audience. On the lower floor is a bar, rooms for administration, the music school and dressing rooms. The auditorium has a 18 meter wide back door that, when opened, permits access to what is presented on the stage to people situated outside, for open air concerts. stage.
