Athfield Architects has taken out the 2012 Supreme Concrete3 Sustainability Award for its extensive refurbishment of the new Christchurch Civic Building on Hereford Street. It is the first building to receive a 6 Green Star Office Design rating.

The design reconfigured the building’s existing service and transportation cores, and added mezzanines to the main office levels. The existing precast concrete cladding panels from the southern facade were removed, reworked and reused on the northern side to create a new extension with double skin facade, and circulation stair and winter gardens behind.

Athfield Architects were also presented with the Excellence in Commercial Concrete Construction award.
