Open Christchurch: The city's most recognised buildings to be open to the public

The people of Christchurch have experienced a lot of change in the last decade - and some of that change is reflected in the cityscape. 

To celebrate the contrast of both the old and the new, 46 buildings have been opened to the public for a one-off look inside. 

"Rebuilding of Christchurch in the 21st century, being a 21st-century city, hasn't happened anywhere else in the world - fantastic," NZ Institute of Architects fellow Barry Dacombe told Newshub.

The modern architecture of new builds has emerged alongside the rich history of the old. 

This contrast inspired Open Christchurch - a festival of architectural excellence.   

"Architecture is everyday public art and yet we can take it for granted," festival director Jessica Halliday told Newshub.

Open Christchurch is modelled on the world's largest festival of architecture held in London. 

Over there you get to see the Queen's quarters, and here in Christchurch the Mayor opens up her lounge at the Civic. 

"People are really enjoying seeing what international visitors to the city get to see from this," Christchurch Mayor Lianne Dalziel said. 

The 46 buildings were chosen according to criteria including sustainability, architectural significance and innovation, as well as whether it helps tell the story of Christchurch. 

"People in Christchurch in the last ten years, that sense of connection has been really severed a bit and this is a chance to reconnect," Halliday said.

The First Church of Christ Scientist is one of the few post-modern styles to survive the earthquake. 

"We've been exposed to architecture much more in Christchurch than other centres mostly because of the earthquake but also because we've had a very good history in architecture," Dacombe said.

Organisers are expecting at least 10,000 people will pop in for a nosey or join the guided tours.

A peek behind the scenes of some of the city's finest - and a chance to reconnect to a place steeped in rich history.
