Aarburg, Switzerland, 2009 – 3rd Prize

Aarburg is a small town near Olten, Switzerland nestled between a bend of the river Aare and a picturesque medieval castle located on a promontory towering over the town. In order to halt the drain of inhabitants and investment from the town, an urban design competition was held on a site next to the train station.

The proposal positions two large and efficient commercial buildings with offices and show rooms next to the stations; and a courtyard building with offices for the city administration at the bottom and elderly housing on top. The volumes form a gate to the city, define the station square on two levels and accentuate the station street while creating a series of public open spaces with distinct character.
