Cranmer Court repair cost too much

City councillors who fought to save the historic Cranmer Court from demolition have conceded defeat, saying the cost of restoration was just too much.

Contractors began pulling down the historic earthquake-damaged apartment complex yesterday in spite of chants of "vandalism" from a small group of very vocal protesters.

Just after 9am, a high-reach excavator nicknamed the "Nibbler" started work on the southeast corner of the heritage listed former Normal School built between 1873 and 1876 in Cranmer Square.

Cr Glenn Livingstone, who chaired a public meeting that voted unanimously to seek an emergency city council meeting requesting a stay of execution from the Canterbury Earthquake Recovery Authority, said restoration costs were the deciding factor.

"I'm satisfied the body corporate made every effort to save the building," he said.

CERA issued a dangerous building notice in April, but demolition was halted while efforts to save the building were explored. A last-ditch offer from an Australian to purchase the building was withdrawn last week.

Cr Livingstone said he learned only on Wednesday afternoon that a demolition contract had been signed and work was set to start at 9am the following day.

He said he was told any further delay to demolition would cost the corporate body some $10,000 a day.

"I do sense the corporate body have explored all avenues."

Cr Helen Broughton, who lodged a notice of motion at 4.30pm on Wednesday urgently requesting CERA to grant a month's moratorium, said the earliest a council emergency meeting could be held would have been next Tuesday.

She said her notice of motion was "only a possible backstop" as an emergency meeting would have required signatures from at least five councillors.

"I think it would have been very hard to get those signatures," she said. "The council are very divided on heritage issues and if people aren't aware of all the issues, they wouldn't sign."

Cranmer Court body corporate chairman David Chambers said the demolition was "all bad news" and came down to "cost and time".

"We've had to accept we cannot continue to pour good money after bad or there would be nothing left to allow people to rebuild."

Mr Chambers said Cranmer Court represented "31 individual families" many of whom were retired and had "no additional nest eggs".

"We can't fix (the building) for the rest of Christchurch," he said. "We just can't afford to."

An emotional Canterbury Arts and Heritage Trust chairwoman Lorraine North deplored the demolition.

"I see this as an act of deliberate aggression and hostility against the people of this community.

"This is a significant historical site. It is very important to our heritage and it is being deliberately and unnecessarily destroyed."

Ms North said CERA was "inflexible and unreasonable".
