The typical Canary Wharf tower configuration of central core with perimeter office zones evolves, in the design for Canary Riverside, towards a rectangular plan made up of three linear ‘slices’ each slipped in relation to each other. The central slice carries the core, while the outer two slices accommodate office space. The resulting plan is common to both towers, and generates the three dimensional form, expressed in elevation as three vertical bays to the east and west.
The plan is also carried through to the roofscape as three levels of terraces. The central core rises to the highest point with the flanking elements stepping down on each side. The heights of the towers are also stepped in relation to one another with the south tower rising higher than the north tower in recognition of the principle east-west axis of Canary Wharf. The towers respect the primacy of One Canada Square, with the overall height not exceeding the ‘shoulder’ of the existing building, while at the same time adding considerably to the skyline.
The building will be clad in a number of external wall systems, including glazing that will incorporate various thermal and solar coatings to respond to the environmental conditions on each facade of the building. At high level, the screens around the plant areas take on the same appearance as the main facade, but will become lighter through the use of louvres that also provide the required free area for ventilation.
The landscape incorporates a series of pedestrian links which enable access to the riverwalk and the podium. Surface treatments are designed to match the existing river and dock wall barriers, and hard paving adjacent to the building will allow cafes and restaurants the opportunity to spill out onto the riverside terraces during the summer.
