Construction is already under way on the 12-storey tower - set to open in 2009 as investment bank Bear Stearns' new European HQ.
HOK design director Larry Malcic said: 'The site is a challenging, non-orthogonal shape. The distinctive elevations draw inspiration from optical art so that, as the observer's vantage point moves, the character and materials of the building change.'
Churchill Place will be dominated by glass, granite or metal, depending on the perspective, added Malcic.
'The northern elevation has a generous amount of glass facade, maximising the amount of natural daylight with minimal solar gain,' Malcic said.
'Stainless steel edges catch light and sun reflections in this northern-Europe location.'
Churchill Place is one of the last projects to be completed within the original London Docklands Development Corporation (LDDC) enterprise zone, which existed for 10 years from 1982.
