To fit the industrial nature of the site, the massing represents a seemingly-reused, post-industrial structure that is enveloped by a curtain of glass, behind which the spatially-articulated concert halls are visible and the large concert hall appears to float in a sea of "rusty gold". The concert house is divided longitudinally into a public area that includes the foyers and a compact internal area that includes the support areas. These areas are connected by the large and small concert halls as well as via the "workshop" and the "educational area". The mostly indeterminate, large foyer is spatially contained by a cascade of stairs that lead you up to the levels containing the concert halls. The new Concert House is always holistically interpreted as a differentiated spatial structure, due to the spatial impression of the house itself as a "single room", the free-floating aspect of the golden concert hall, the offset alignment of the suspended levels, the shaping of the multi-storey airspaces and the presence of an atrium that allows daylight to reach areas inside the complex. The big hall is neither a "shoebox" nor a "vineyard". Some of the seats for the visitors are grouped asymmetrically around the stage on balconies that protrude from the slanted walls. The dropped ceiling in the room consists of an accordion of multi-layered, golden, shimmering plywood panels. Large, sound-reflecting "baldachins" that are suspended from the golden ceiling above the stage serve to "purify" the sound. The spatial and acoustic conditions within the small hall are variable and can respond optimally to meet a wide variety of requirements.
The structure is designed as an adaptable and economic construction made of a composite of reinforced concrete. The basic idea was to create a ground level that was free of support structures, insofar as possible, as well as independent of the upper and lower floors. For this reason, the vertical load transfer system relies on just seven support rows, each with four columns. The concert halls were developed as steel or steel composite structures and can be decoupled from the rest of the building in order to isolate vibrations. The façade, which is approximately 1 meter thick and made of a suspended, folded "glass curtain", consists of a triple-glazed insulating material made of white glass in order to achieve the highest degree of transparency possible with an optimized g-value and ensure the amount of protection necessary from the sunlight.
