The local authority approved the 40,000m 2landmark regeneration project late last year.
According to Sheppard Robson creative director Tim Evans, the building is 'broken down by four stepped elements'.
He continued: 'From street level these elements are further fragmented and enriched through an environmentally responsive cladding system.'
The architect claims that alternate 'opaque and transparent panels are distributed across the facade to respond to the site's orientation, creating a passive solar-shading system and optimising views across the city'.
The building is due to start on site in August 2006 and will be completed in early 2008.
