The cost of reinstating the Christchurch Cathedral has skyrocketed to 154 million dollars.

The building has laid in ruin since the Canterbury earthquakes, with strengthening work now underway.

The estimated cost to reinstate the cathedral was 104 million dollars.

But the Christchurch Cathedral Reinstatement Project has revealed that cost is now more than 154 million dollars.

That includes work on the cathedral, landscaping, two new external buildings and associated costs.

Peter Guthrey, Chair of the Christ Church Cathedral Reinstatement Trust said “the fundraising target is ambitious yet achievable, and we are confident that a wide range of people here in New Zealand and from around the world will provide support. “

“The good news is with over $100 million already raised, we are already two thirds of the way to our goal.”

What are the key changes to the Cathedral?

• Small changes will make the western porch more open and welcoming, while retaining the design and original materials where possible. It will be slightly deeper so it can accommodate more people. Adding a skylight and deeper windows will allow in more natural light.

• The new vestries, (replacing the 1960s versions), will be built in the same palate of materials as the Cathedral itself, matching the Cathedral roof form.

• The north vestry will be a first-class rehearsal and library space for the Cathedral Choirs. It will include separate changing area for the new Girls’ Choir.

• The south vestry will will provide space for clergy, vergers and servers to assemble and robe before services, with the first floor reserved as the plant room.

• The plan is for the organ to be removed, overhauled and reconfigured to improve its performance.

• The reinstated Cathedral will be more adaptable internally for various sized groups and activities. The overall seating configuration will be more flexible, either radial or linear. We plan for a section of the Crossing floor to be able to be raised or lowered to improve visual connection depending on the kind of service or event.

• Modern, efficient underfloor heating will make the Cathedral more comfortable.

• The much-loved Tower will be rebuilt in its original position and be very similar in outward appearance to its predecessor. It will be base isolated to achieve the required seismic 3 standard. It will have a working belfry, and the stairs and lift will provide access to the belfry, viewing platform and the lower courtyard to the north.

• A new Visitors’ Centre will be located to the north comprising a café on ground level, and retail and museum space below ground, opening into a lowered courtyard.

• The museum will provide opportunities for visitors to learn about the history of the Cathedral, to engage with artefacts, and purchase mementoes at the gift shop.
