The architects are angered by alterations to significant buildings and fear the university administration is destroying the famous "bushland campus".

Their concerns will be aired in a DVD shown to Newcastle City Council tonight in response to Newcastle city councillor Ian McKenzie's motion to investigate heritage listing.

Specifically, the architects object to recent changes to Staff House, which was designed by Professor Glenn Murcutt, who won the world-renowned Pritzker Prize in 2002.

Those on the DVD include Newcastle's former architecture dean, Professor Lindsay Johnston, Professor Peter Stutchbury, Professor Richard Leplastrier and Professor Murcutt.

Professor Johnston described some of the changes as "vandalism".

Professor Murcutt likened the changes to Staff House, which houses the University Club, to "Bunnings on a Saturday" and said as the original architect he should have been consulted.

The university felled trees including a Queensland lacebark planted around 1969 as part of a new outdoor eating area at the building.

"It's destroyed a building," Professor Murcutt said.

Professor Murcutt said changes to landscaping were changing water courses.

"It's to me an absolute desecration," he said.

"I just cannot believe that a body of intelligent people would allow this sort of thing to happen."

Newcastle University vice-chancellor Nick Saunders was unavailable for comment.
