This prestigious urban programme remodelled the whole perimeter block, marrying major rehabilitation and new construction.

Curved faceted facade, sealed glazing fitted on a frame like a mount, glass set in mirror finish capping, moulding chiselled on the glass like a claw: the treatment of the «Colonnade» facade brings to mind the work of a jewel maker. Representative of the entire programme, the envelope continues in a curve with a radius of 245 metres over a length of 54 metres.

The programme includes 23,400 sqm. of offices, 242 parking spaces and a 450-cover staff restaurant.
