The cost to build a custom granny flat in Sydney varies significantly, but generally ranges from $150,000 to $300,000, depending on size, design complexity, and site conditions. Basic one-bedroom granny flats can start around $120,000, while larger, more luxurious two or three-bedroom options can exceed $250,000. Factors Influencing Cost:

  • Size and Design:Larger granny flats with more bedrooms and custom designs naturally cost more. 
  • Materials and Finishes:High-end materials, custom cabinetry, and premium finishes will increase the price. 
  • Site Conditions:Difficult terrain, excavation needs, and connection to utilities (sewer, power, water) can add to the cost. 
  • Council Approvals and Fees:Council fees and approval processes vary and can contribute to the overall cost. 
  • Turnkey vs. Basic Fit-out:A "turnkey" granny flat includes everything ready to move in, while a basic fit-out may require additional expenses for appliances and furnishings. 
  • Builder's Fees and Margins:Different builders will have varying pricing structures, so it's essential to compare quotes carefully. 

Cost Breakdown Examples:

  • One-Bedroom Granny Flat: $120,000 - $180,000, depending on inclusions and site factors. 
  • Two-Bedroom Granny Flat: $150,000 - $250,000, with more variation based on design and site conditions. 
  • Three-Bedroom Granny Flat: $180,000 - $300,000, particularly if custom designed or requiring significant site work. 

Tips for Accurate Budgeting:

  • Get Multiple Quotes:Obtain quotes from several reputable granny flat builders to compare pricing and inclusions. 
  • Factor in Site Costs:Don't underestimate the cost of site preparation, excavation, and connections to utilities. 
  • Understand Standard Inclusions:Carefully review what is included in each quote, including fixtures, fittings, and finishes. 
  • Consider Future Costs:Factor in ongoing costs such as council rates, insurance, and potential maintenance.
