The city of Busan is characterized by its unique geographical location: mountain slopes rising directly from the shores of the Pacific Ocean. Magnificent nature contrasts with an enormous population density in the urban fabric and the resulting urgent need for urban public space in the tension between mountains and sea.

The two proposed new public squares are intended to create a new emphasis in the perception and use of public space in Busan City, but also to function as a new central place:

- Mountain Plaza is oriented to the mountains and the skyline of Busan
• Ocean Plaza faces the sea (annual "New Years Sunrise Festival")

The basis for the design and use of the squares is the historical Korean model of "madang", a traditional public spontaneous urbanity as a gathering, performance or sudden event. The two main functions (opera and theatre) were also each oriented in a separate volume to one of the two squares .

A thin transparent and translucent skin protects the interior of the building from rain and sun and connects the volumes of the two main functions into one building. In the center, the building opens up and allows public space to flow through to connect the two squares.

As a landmark, Busan's new opera reflects these unique natural and urban-urban energies and combines them to create "Madangnoli" - a space for art and performance at Mountain and Sunrise Plaza. It creates an urban harmony for traditional and vernacular performances, performed by Busan residents and visitors, that is constantly changing, depending on the time of day.

The construction of the building is designed like a sound wave, sustainable and environmentally friendly it reflects the new future of Korea.
