Tapered, concrete six-storey office building with a triangular plan

The block occupies a site between the Liestal station square and the head office of Basellandschaftliche Kantonalbank. Due to the constrictions of the site, the building’s footprint had to be smaller than its upper storeys, resulting in a downward tapering shape.

The basic motif of the facade design results from the 2.65m-wide grid used for the office design. The facade is evenly divided into facade elements in dark fair-faced concrete, with the width of each element being that of the office grid.

The grid pattern was chosen to allow the floor space to be used for different-sized units. The floor spaces are arranged around a central services core and provide the flexibility to accommodate a range of functions.
