The arched roof, oversized awning and internal railing and loft are supported by a host of pipes salvaged from old sewer lines. The supporting structure enhances the airiness of the design, while the side walls are made from masonry brick. The huge and lively bas-relief art set on the outside walls is a piece by Jorge dos Anjos. It is deeply influenced by African art brought to Brasil during the time of the slave trades. His reliefs are energetic, poetic and elemental.
