DEMOLITION: The Lyttelton Tunnel Control building.

The Lyttelton Tunnel control building, designed by the late Peter Beaven, will be demolished because of earthquake damage.

The NZ Transport Agency (NZTA) this afternoon said the building was considered dangerous and it had asked the Canterbury Earthquake Recovery Authority to demolish it.

The category 1 heritage-listed building was red-stickered after the quakes because of rockfall risk.

NZTA highways operations manager Pete Connors acknowledged the news would disappoint some, but the agency had looked exhaustively at repair options and worked with the Historic Places Trust to try to save it.

A 2011 report put the repair cost at more than $3.5 million over the cost of a new building.

''Because [it] is classified as dangerous and is in the path of potential rockfalls ... [the NZTA] could no longer put this tough decision off,'' Connors said

A replacement building would reflect Beaven's design and be built away from the rockfall path, he said.
