The project responds to the concept of urban space with the principle of porosity with an inner passage, a passage to the courtyard and two external staircases that connect the three levels of Kochereiplateau, Attisboulevard and Aarekai. The "Kocherei" building, as a historically valuable structure, is integrated obviously into an ensemble of three buildings and referred to as "Bernd, Hilla and Max".

Kocherei, Riegel, Quader and Sockelbau offer a diverse mix of uses including commerce, production, services, sales, gastronomy and a club room or a large-scale distributor. In addition, very different types of flats are proposed: Movements, loft flats, maisonettes, storey flats or through flats with a view of the courtyard and the Aare.

The industrial style is continued in a contemporary architectural expression: The supporting structure of the Kocherei is extended identically with its concrete lattice and supplemented with an insulated wooden lining from the inside. The Riegel and Quader are sheathed in a shell of prefabricated wooden elements and clad on the outside with photovoltaic elements. A lush greenery with shade plants enlivens the courtyard space.
