December 2007

Michelle Renshaw decided to build an extension to her basement flat.


July 2008

Port Adelaide Enfield Council approved the construction of the corrugated galvanised steel clad addition.


December 2008

Port Adelaide Enfield Council notified Michelle that since the Zincalume cladding did not comply with the approval conditions she must replace the Zincalume with "corrugated galvanised iron."

Michelle pointed out that there are no "galvanised iron" products available and that she had clad the building with "galvanised steel" - which the Planning Department had approved.


April 2009

Port Adelaide Enfield Council 's counsel advised the Environment Court's Commissioner Hodgson that there was no room for negotiation and Michelle must either comply with their December 2008 directive or fight the Council in Court.


August 2009

Her Honour Judge Trenorden ruled that whilst the expert witness had established that Zincalume is in fact "corrugated galvanised steel," Michelle had breached the Development Act because "a reasonable person would not have expected the cladding to be Zincalume."

Zincalume has been in common use since the 1970s.
