The aim of the project is to achieve two seemingly contradictory objectives.

• The completion of the city's urban fabric, and consequently the search for continuity by conforming to the historical urban fabric and the surrounding residential buildings.
• The creation of a new focal point in the city, consequently a building easily seen and recognizable with the capacity to create a new pole of attraction for the city.

 The volumes which enclose the hotel, the conference and meeting centres and the concert hall,   go to replace the parts missing in the medieval urban fabric.

The scheme develops starting from the east of the area and is the connective tissue of the urban fabric filling the voids and transforming the built-up sections. Continuing towards the western extremity of the area in front of the bridge at the end of Martin Luther Strasse, it becomes an urban catalyzer, a magnet for new activities in this part of the city.

The western edge of this area is an important urban pivot between Martin Luther Strasse, a two-way street which runs from south to north through the old town centre; the Unter den Schwibbogen which runs parallel with the Danube and briefly skirts the ruins of the Roman fortification; the Ostengasse which runs from the east gate of the medieval wall and terminates here; the pedestrian pathway along the river bank; and lastly the bridge spanning the Danube. The Concert Hall will be built in this undeveloped space, and the remaining surface will be raised to the level of the Ostengasse to form a square onto which the Concert Hall will face.

The volumetric layout of the complex formed of the edifices where the various activities will be carried out, will be united under an immense black-tiled roof which covers the entire complex with a single line gutter encasing the volumes of the points where they terminate.
