This extension to Aargauer Kunsthaus by Herzog & de Meuron and Rémy Zaugg opened in 2003. Swirling staircases can be seen through green glazing at the entrance. The stairs lifts the visitor up to the vast green roof. This roof of grass tilts down with pre-grown panels and meets the street at an angle.
The pure white background of the exhibits often opens up to green-tinted glass, reminding the visitor that human creation mimics nature, indeed that our built environment is no more than intervention and arrangement of nature.
The building seeks to fit quietly into its urban surrounding, shaping visual cues and light to introduce art and unity with plantlife.
