Pedestrian

Architects of the refurbished Bahnhofstraße leading to Böblingen’s main train station, fell back on tradition: light and stone are the main elements. Building material would be a free used of the modern parameters: the artificial lighting above the pedestrian zone illuminates the imported granite and brings out the distinguishing array of stone colors.
To nip the notion in the bud: these are not stone types imported from Asia. We are talking about Spanish and Portuguese products. Stuttgarter Zeitung reports that the paving set off a lengthy debate at the end of which the city decided against „cheap imports from countries working with child labor and wage dumping“.
