Portcullis House, UK

The new Parliamentary building, located within a World Heritage site next to the Palace of Westminster, is characterised by its distinctive bronze roof form and air handling 'turrets'.

The roof structure is made up of clusters of eight girder legs supporting each turret, all clad with 6mm aluminium bronze plate (with an 80% copper content).  This alloy is also used for fenestration below the roof on the 'blast frame' for ductility and strength.

The judges in the Copper in Architecture Awards viewed the well-considered use of aluminium bronze alloy in both sheet and cast forms to be an innovative use of material, particularly appropriate to the building's prominent location and able to meet challenging technical requirements including a 120 year design life.
