N.Z. Quake City Puts Faith in Cardboard Cathedral

When Japanese architect Shigeru Ban designed a new cathedral in

earthquake-devastated Christchurch, he chose the most unlikely of

materials — cardboard — for the landmark project.

The New

Zealand city's magnificent Gothic revival cathedral hewn from local

basalt was irreparably damaged in the 6.3-magnitude earthquake that

claimed 185 lives on February 22 last year.

Urgently needing a

temporary replacement, the Anglican Church commissioned Ban — who

donated his services gratis — to draw up plans for a place of worship

to house Christchurch's faithful.

The result is the so-called cardboard cathedral now taking shape on the quake-scarred city's skyline.

Built

from 600-millimeter (24-inch) diameter cardboard tubes coated with

waterproof polyurethane and flame retardants, it will be a simple

A-frame structure that can hold 700 people.

"It will be a huge milestone towards recovery for Christchurch," project manager Johnny McFarlane said.

"It's going to be a great building to walk into, it's very light and airy and gives a good sense of dominance and scale."

Ban,

a world-renowned architect who has been hailed by publications such as

The Wall Street Journal and Time magazine, sees the cathedral as a way

his profession can help Christchurch's shattered community recover from

the quake.

While the 55-year-old takes on major commercial

projects such as office buildings and tourist resorts, he is also a

pioneer in "emergency architecture" which can be rapidly erected in

disaster zones.

He began in the mid-1990s, working with the UN to

erect temporary shelters for refugees after the Rwanda genocide and has

since helped with relief efforts in scores of humanitarian emergencies

from Turkey to his native Japan.

"This is part of my social

responsibility," he told AFP. "Normally we (architects) are designing

buildings for rather privileged people … and they use their money and

power for monumental architecture.

"But I believe we should build more for the public… people who have lost their houses through natural disaster."

He

said many so-called natural disasters such as earthquakes were worsened

by the failure of man-made structures and architects had an obligation

to help.

"People are not killed by earthquakes, they're killed by collapsing buildings," he said.

"That's

the responsibility of architects but the architects are not there when

people need some temporary structure because we're too busy working for

(the) privileged. Even a temporary structure can become a home."

A

common feature of Ban's emergency architecture is the use of recycled

material, including shipping containers and beer crates, which were

filled with sandbags to act as shelter foundations after the 1995 Kobe

earthquake.

But his signature material is cardboard tubes, which

he says are readily available after disasters, unlike traditional

materials such as timber and steel.

He has used them to build

everything from a concert hall in L'Aquila, Italy, a schoolhouse in

China's Chengdu and a "paper church" in Kobe, which was erected in just

five weeks.

"The material is available everywhere in the world,"

he said. "Even when I was building a refugee shelter in Rwanda I found

the paper I needed for my structure in Kigali.

"So anywhere I can

go I can find this material, it's very inexpensive and normally this is

not a building material, so it's easy to get in the emergency period.

It's also lightweight and cheap."

Christchurch's new cathedral,

due to be completed in April next year — 132 years after the

consecration of the original stone version — is the largest cardboard

structure Ban has designed.

The church, insurance and public

donations are paying for the NZ$5 million project ($4.2 million) for

which local builders have offered discount prices.

It has a concrete base, with the cardboard tubes forming two sides of the A-frame and containers helping brace the walls.

One

end of the cathedral will be filled with stained glass and a polycarbon

roof will help protect it from the elements, giving a lifespan

estimated at 50 years.

Church authorities envisage it being used

as a cathedral for only 10 years, until a permanent replacement is

built, although Ban said the enthusiastic response in New Zealand to his

innovative plans could change that.

"If people love it, it will be permanent, I hope that's going to happen," he said.

Building

authorities in Christchurch pored over the plans and declared they

fully meet earthquake standards, while even locals initially sceptical

about the cardboard concept have been won over.

"I thought it was a bit of a strange idea but now I think it's really cool," Christchurch resident Hunter McKenzie said.

"It's actually good just to get the cathedral up and running and try to get the city back to normal."
