Queenstown firm Elliott Architect took out a heritage prize for the project at the awards held in Queenstown on Friday.
Judging panel head Queenstown architect Michael Wyatt said the award recognised a "celebrated piece of the city’s folklore given a new lease of life". The other winner in the heritage category was McCoy and Wixon Architects, of Dunedin, for the restoration of St Patrick’s Basilica, in South Dunedin.
"Working closely with the client, the architect has successfully effected a dramatic change to the use of the building, and its relationship with the street and other church functions," Mr Wyatt said.
McCoy and Wixon was sole winner in the commercial architecture category for its design of Mercy Hospital’s day-stay facility Manaaki.
Of the 17 projects recognised in the awards, 11 were houses, nine of them new builds.
The two winners in the public architecture category were Warren and Mahoney Architects, of Queenstown, for Invercargill Airport, and Mason and Wales Architects, of Dunedin, for the Wanaka Fire Station.
The winners are eligible for the New Zealand Architecture Awards.
