Existing columns as protagonists. The mighty existing columns of the former Coop wine storage in Basel's Lysbüchel neighborhood tell the story of the building's history in an impressive way. They are the most striking elements of the existing structure and form an important design starting point.

In order to keep their effect tangible despite the small-scale nature of the new residential use, they are exposed and staged in various ways: In the apartments, which span the width of the building, their bulky monumentality is an experience in itself – whereas in the two 'rues intérieures' (internal streets), that run lengthwise through the building, they appear as a sequence.

The city in the house. Thus, the columns also form the starting point for the internal organization of the house: the actual urban development is defined by the existing building - but along the 'rues intérieures', a city within the house takes shape. This internal system not only provides access to the stairwells, the communal rooms, and the laundry rooms, but they also enable a variety of apartment typologies (1.5 to 7.5 room apartments) for all generations and lifestyles.

On the mezzanine floor, the domestic sphere links up with the urban one – here the inner street opens into the transverse entrance halls and invites one into the house via stairs and ramps. The commercial spaces and the café are located at ground level at the heads of the building, directly addressing the city. The network of paths finds its end in the community room and the collective roof terrace.

Ecological responsibility. In addition to the design-defining expressiveness of the existing columns, ecological sustainability also motivates the careful treatment of the existing structure. In this case, 42% of the building's grey energy was saved by continuing to use the old structure. The photovoltaic system and the groundwater heat pump make the building two-thirds self-sufficient in total energy consumption.
