SESC is an organization responsible for offering extra-curricular education, social, cultural and sports activities for employees in commerce and services and for citizens as well. The program is organized in four groups of spaces: cultural, sports, social and health. All these spaces designed for multiple uses are integrated and house different activities. The program also includes administration, maintenance, and infrastructure areas. Seeking to suit multiple and specific uses, the building is formed by two volumes: a vertical cylinder cut by a transversal plane and a curved horizontal volume, facing a public park. Within the horizontal volume, there are three public levels: 1. The ground floor contains a large entrance hall leading to a theatre, a gym, a library, an indoor playground, and others facilities. 2. The second floor is visually linked and connected to the first floor by a void and a ramp. It also contains an exhibition hall, a lobby, a restaurant, the indoor and outdoor swimming pools, the arena’s entrance, and the administrative areas. 3. The third floor is a rooftop terrace with a garden, and a view of the park, the city of Jundiai, and a protected mountain range called “Serra do Japi”. Within the cylindrical volume, there is the multi-purpose arena with three tiers of seats linked to the levels of the horizontal volume by a surrounding hall.
