Leading architect and designer Chris Moller has slammed the decision to demolish the Aniwaniwa Visitors' Centre at Lake Waikaremoana, describing it as "outrageous".
Mr Moller, who fronts the TV3 programme Grand Designs, was speaking on Kim Hill's RNZ show when he described the decision by the Department of Conservation to pull down the 40-year-old John Scott-designed building as showing a lack of understanding for Mr Scott's work.
"The Scott family is devastated and rightly so," Mr Moller said.
"It is one of his great works - I am quite upset about it."
Mr Moller, who described Mr Scott as a mentor, said the Institute of Architects had been "one hundred percent" behind saving the building which was now in the last stages of coming down.
