Estimates for a small start in Australia, not guarantees.

What it is

A licensed building business that quotes, manages and delivers home renovations, extensions and similar projects. You coordinate carpenters, plumbers, electricians and other trades, and hold responsibility for quality, timing and compliance.

Your first three steps

  1. Check your state or territory building licensing body for the licence class, qualifications and experience you need
  2. Get quotes for public liability, contract works and tools insurance, and ask about home warranty insurance requirements in your state
  3. Set up an ABN, a simple contract template and a list of reliable subcontractors, then pitch to past contacts and local real estate agents
Who pays

Homeowners, landlords and small property investors planning renovations or extensions.

How it makes money

Fixed-price or cost-plus contracts per project, with a margin on labour and materials. Payments are usually staged as the job progresses.

Skills that help
  • Building knowledge and site supervision
  • Accurate quoting and budgeting
  • Managing subcontractors and schedules
  • Clear communication with clients
Watch out for
  • A state or territory builder's licence is generally required for larger residential work, so check the exact thresholds with your licensing body
  • Home building compensation or warranty insurance may be required above certain job values, check your state
  • Startup costs depend on what you already own: budget for licence fees, insurance premiums, a work vehicle, tools, site equipment, software and enough working capital to pay subcontractors and suppliers before clients' staged payments arrive
  • Workers compensation insurance once you hire staff
  • Cash flow risk: pay subcontractors and suppliers on time even if a client pays late
  • Written contracts, variations and council or private certifier approvals need to be handled properly
