Project Description & Details

The District is New Zealand’s ultimate business location in the heart of the growing urban environment at Auckland International Airport, offering the ability to work, play, rest, shop, dine, and fly. Fearon Hay Architects were selected to create a flexible space for hosting events and meetings plus introduce the strategy and opportunities behind the developing precinct. ‘The Cloak,’ or Te Kaitaka in Maori, is a 208m2 greenroof meeting a copper mesh ‘cloak’ screen shrouding two walls of the showcase building positioned in the centre of the airport’s new business district.

The contoured living greenroof was established over a shaped engineered timber frame, providing the shoulders from which an encircling and distinctive woven mesh screen forms, creating The Cloak. With some roof faces up to 30 degree pitch, the greenroof application in an exposed location required technical design expertise and LiveRoof‘s pre-vegetated 150mm deep extensive system was selected by Stormwater360. Working with engineers to develop a lateral support system on the 20+ degree roof faces, they used mechanically fixed perforated aluminum ‘Roof Edge’ to support the loads. Plant selection to match Fearon Hay’s brief as well as sustain the steep slopes and windy conditions was also a technical task. This was achieved using a selection of pre-trialed native New Zealand grasses, groundcovers and sedum plants pre-grown in the LiveRoof® modules for a four month period prior to installation. The architecture of ‘The Cloak’ – Te Kaitaka – demonstrates innovative design and sustainable operation.
