Our history Quality, since 1985 Home > About Us > Our History Covering Australia for over 30 years Spanline Australia was formed in 1985 following the creation and development of the Spanline Home Additions Building System. Spanline was founded with the vision of changing the way Australians play. We all love the outdoor lifestyle and Spanline makes it easy to enjoy it even more. We were the first to produce a fully engineered, all steel patio roofing product of unrivalled quality. This unique product is still central to the Spanline Home Additions building system. Its popularity is one of the main reasons you can now find Spanline in virtually every capital city and major regional centre around Australia. In 1993, Spanline moved towards full system franchising and since then has developed sophisticated franchise systems, codes, procedures and practices that allow for a more proactive and rewarding business. In fact, Spanline has grown to be Australia’s largest home additions builder and the market leader. Each year, we enhance the outdoor areas of more than 7000 homes by bringing their living spaces to life. Yours can be next! Want to learn more about the Spanline difference? Contact us today
