This creative building was represented by Portuguese firm OODA to the design competition for the Busan Opera House in Busan, South Korea. Architectors placed this seashell like building on the edge of the sea and such solution looks very harmonious. This concept of Opera House contains areas for a huge range of cultural activities including operas, theater, sporting and musical events. “The grand opera auditorium features flexible stage locations and seating arrangements with rotating platforms enabling large and small scale events to occur within the space. Accommodating the needs of different concerts, visitors may have a variety of perspectives to view performances with a central stage and perimeter seating or a single view with all seating oriented in the same direction. A secondary multipurpose theater within the smaller volume is interconnected with a banquet hall, convention center, shopping, cafes and restaurants.”
