The development was conceived as two black brick boxes, a longer one addressing Abbey Road and the other, perpendicular to the first, addressing the river. The boxes were raised above a plinth of parking and service accommodation, above any flood risk from the River Roding. The external terraces are created by a sinuous white ribbon which wraps the building. As this ribbon travels around the building, it is articulated to specific elements such as points of entry or significant corners which are visible from a distance.
Following grant of consent, the development changed hands several times, and was finally constructed by Quadrant Construction working with RMA Architects whose stage 4 drawings stayed true to the planning intent.
