The 5,000m 2five-storey concrete-framed building is clad in full-height glazing animated by slender panels of blue and green glass, a reference to the striped awnings of the neighbouring market stalls.
Escalators rise up between the main facade and a three-storey projected glazed screen creating a direct link between the street and the upper floors.
David Adjaye said: 'My aim was to create a glamorous place that's open to everybody - an accessible civic building.'
The project follows Adjaye's Idea Store in Chrisp Street, Poplar (AJ 12.8.04). Seven Idea Stores are planned in all.
