Consumption is a major component of modern life. Despite their significance in economic, urban development and social terms, commercial structures have featured very little in the architecture debate for decades. However, in recent years, planners, project developers and investors have been rethinking this for cities. Changing production forms, global trade routes, increasing online trading and new sales concepts require a rethink of spatial schemes and architecture. New urban concepts for the retail trade, altered sites and sensible mixed uses are revitalising city centres today. Just look at Sankt Augustin. A modern shopping centre is being built in two construction stages, not only to cover daily needs, but also to give definitive shape to the face of the centre of Sankt Augustin.
