The uniqueness wasn't confined to the firm's treble, on a night where 10 awards were presented in front of a crowd of about 60.
Particularly distinctive was a second education category award for Auckland firm RTA Studio's work on the new buildings for Wairoa Maori school Te Kura Kaupapa Maori o Ngati Kahungunu o Te Wairoa.
Having opened with a roll of about 10 in 1994, it reached its dream with the opening of the two open-plan classes in April last year, when the roll was 79.
Napier architect and awards jury convener John O'Bryan said it showed architecture's power to enhance learning.
Young people were drawn into the design process for a Maori immersion school interwoven with stories of culture and environment, helping, for example, to choose the building's primary colours, he said.
The judges commented: "This work is true architecture, interwoven with references to the past that will now inform the future, and with significant cultural and environmental elements that have been adapted into physical form with great finesse."
The Clifton Road Reserve toilets near Haumoana brought accolades for Napier designers Citrus Studio, in small project architecture, and two homes, in Havelock North and at Waimarama, also featured.
