Arena Do Morro is a permeable gymnasium in the Mae Luiza region of Brazil and it was designed by the Herzog & De Meuron architectural practice as a venue for public events.
The project combines traditional elements to create the unifying roof which is a symbol of the physical and social activities going on in the town as well as adding a new landmark for the region. Instead of offering a uniform project, the structure is comprised of a series of open panels which are diagonally oriented and overlapping to permit the light to pass while also protecting from the water.
The facility contains a large sports field which has seats for 420 persons, multipurpose rooms for dance or education, changing rooms, public restrooms and a terrace which offers a view toward the ocean. The interior is defined by curvilinear enclosures created with vertically stacked bricks which rotate to create several degrees of openings to the exterior while also acting as thresholds to promote natural ventilation.
