The Yellow Treehouse Restaurant by Pacific Environments Architects NZ.Landmark new offices, a minimalist cave and the famous Yellow Treehouse Restaurant are among designs recognised in the 2010 New Zealand Architecture Awards.

Wellington-based architect Gerald Parsonson, convenor of the awards jury, said the quality of winning entries was very high. "We thought the residential projects pushed the boundaries more this year, showing a real inventiveness and uniqueness, from the Mediterranean feel of a clifftop villa overlooking the Sumner inlet in Christchurch to a beautifully orchestrated stone-clad courtyard house in Wanaka."

Jasmax captured four awards with its NZI Centre at Auckland Viaduct a winner in the Commercial, Sustainable and Interior Architecture categories. RTA Studio was a winner in the Commercial and Sustainable categories for its Ironbank Centre and Athfield Architects took two residential awards for the Clements House in Christchurch and the Fox-Hansen House in Nelson.

Jurors said the NZI Centre had set new standards for office space and expectations of corporate citizens, praising its elegance, quality and stimulating interior and sustainability principles that are intrinsic to the building’s design. Ironbank was judged to have "broken the mould". Other winners include:
