Three New Zealand buildings have been shortlisted for a global architecture competition judged in November in Barcelona.
The new Waitomo Glowworm Caves Visitor Centre, the Nelson Marlborough Institute of Technology arts and media building in Nelson and a Grey Lynn house are up for World Architecture Festival prizes.
The Waitomo building was designed by Wellington's Architecture Workshop whose founding principal Chris Kelly said the competition was a "sudden-death" format.
"You have 15 minutes to convince a jury that your building deserves to be a winner. But making it on to the shortlist is a great affirmation for any architect," Kelly said.
Jeremy Smith of Nelson practice Irving Smith Jack Architects said interest in multi-storey timber buildings was growing after the Christchurch earthquake.
