Building codes will also come under fire during the speech."It is now illegal to build a cheap house in Australia," Bragg will say.The centrepiece of Bragg's speech will be a commitment to replace the National Construction Code with a new 80-page "Basic Australian Standard".The codes set minimum requirements for the safety, health, amenity, accessibility, and sustainability of certain buildings, as detailed in over 2,000 pages.The Coalition's new standards will focus on cost-effective structural, fire safety and health-related building standards."Anything else like mandatory ramps, flattened shower flooring or reinforced walls would be optional extras," Bragg will say."The house won't be gold-plated but it won't fall apart That is absolutely ridiculous," O'Neil told the National Press Club in May.The government is not far off presenting a final plan to the building minister later this year to streamline the code, Treasurer Jim Chalmers told ABC Radio National on Wednesday.Bragg has also called for the creation of a federal pattern book of model homes that could receive automatic approval from the states and territories.For the latest from SBS News, download our app and subscribe to our newsletter.
