Winter Gardens get quake upgrade
Auckland’s most iconic greenhouse will close its doors as it is strengthened for earthquakes, despite Auckland being a low earthquake risk.
The Auckland Domain Winter Gardens will shut its cool house for four months and then its tropical house for five months as roof connections are strengthened, and a chimney is braced.
The strengthening of the Victorian-style glass houses was part of Auckland Council’s response to impending earthquake legislation triggered by the 2012 Christchurch Earthquake, which is likely to be implemented in July.
A building is regarded earth- quake prone if it is less than onethird of the strength required for a new building in the same location in moderate earthquake shaking.
Auckland Council’s director of community services Ian Maxwell said the building wasn’t dangerous other than in a moderate earthquake.
Maxwell wouldn’t say how much the work would cost because it was commercially sensitive.
In 2014 economist Ian Harrison released a report showing strengthening of Auckland buildings to the required standard would cost $3 billion.
Maxwell said visitors wouldn’t notice any difference when the gardens were reopened.
In December 2015 a seismic assessment concluded the Winter Gardens were earthquake prone.
