Casa da Musica, designed and built at the beginning of the 21century by OMA a dutch architectural firm led by Rem Koolhaas, is a large concert hall with many rooms. Appart from its irregular shape, the enveloppe of the building is not revealing the intense complexity of the interiors. This drawing is showing both at the same time. Between the map and the radiography, it gives a familiar depth to an institutional monumentality.
