Renovation & Extension Costs


I would like to share the Renovation & Extension Costs guide that I have found on the net. Please see the 09webspringcostguide.pdf attachment file.

What is your though about the costs? Do you think they are realistic?

What is the actual cost of your extension?

Nice one...I'm going to try and find a more uptodate version of this.

We are thinking of an extension and I was contemplating costings...this document is a great start
Dave - are the actual rates that Electricians and Plumbers charge higher or lower than the above rates?


Higher. Electricians and plumbers expect $70-80 + GST per hour + callout on an by the hour basis. Bit cheaper for a larger fixed price job.
