The 1888 Gothic revival presbytery beside St Patrick's Catholic Cathedral in Auckland CBD is an earthquake-prone building.
Cathedral general manager Kevin Sherlock said Auckland Council had assessed this unreinforced brick masonry building and added it to its dangerous building list as part of a wider audit of city buildings, now under way.
An upgrade and seismic strengthening of the two-level red brick structure on the corner of Hobson and Wyndham Sts and St Patrick's Square has been planned for some time. In 2002, the cost estimate was $1.7 million, Mr Sherlock said.
A fundraising campaign will have to be mounted for the Category A heritage building on the Historic Places Trust register and scheduled by Auckland Council.
The presbytery, designed by Edward Mahoney & Sons, is now 125 years old and the Catholic Times reported on February 25, 1888, how the planned premises would serve the community.
