Owner-Builder Support in Box Hill, Eastern Melbourne
An owner-builder is a homeowner who takes on the role of head contractor for their own project, coordinating trades directly instead of hiring a licensed builder. Done well it can save 15 to 25% of the total build cost. Done poorly it is a very effective way to lose your savings, your marriage, and 18 months of your life.

Council rules and overlays for owner-builder support in this area
Owner-builder work is assessed the same way as builder-led work. The building surveyor and council only care that it complies, not who is building it - but you must give your VBA certificate of consent to the building surveyor before a building permit can be issued.
The 3 decisions that shape your owner-builder support in Box Hill
Certificate of consent
In Victoria you need a certificate of consent from the Victorian Building Authority (VBA) before a building permit can be issued for owner-builder domestic work costing more than $16,000 (labour and materials combined). You apply through the VBA360 portal after completing the owner-builder eLearning assessment, and you can generally only be issued one certificate for a single home on a property once every 5 years.
Insurance and warranty
Owner-builders cannot take out domestic building insurance for their own work. If you sell within 6 years of completing work that cost more than $16,000, you must give the buyer domestic building insurance and a defects inspection report, which can limit resale.
What you personally can do vs what needs a trade licence
Plumbing, gas and electrical work always need licensed, registered trades. Most other work you can do yourself if you are competent, but structural design must be signed off by an engineer.
