Fixed Price Turnkey Build Contracts Explained

When planning a new home or development, choosing the right construction contract can significantly impact your financial outcome and overall experience. At Builder Brokers, we specialise in connecting clients with trusted builders using Fixed Price Turnkey Build Contracts – a preferred choice for those seeking certainty, transparency, and simplicity.

What Is a Fixed Price Turnkey Build Contract?

Fixed Price Turnkey Contract is a building agreement where the builder commits to delivering a fully completed home at an agreed, upfront price. This contract covers all construction and finishing works required to make the home ready for immediate occupancy – simply turn the key and move in.

Key Inclusions of Fixed Price Contracts

  1. Fixed Price Component
    The core benefit of a turnkey contract is price certainty. The total cost is locked in from the start, reducing the risk of unexpected cost overruns. This fixed price includes:
    • Construction costs
    • Materials and labour
    • Standard inclusions (flooring, cabinetry, appliances, etc.)
  2. Allowances for Prime Costs (PC Items)
    PC allowances cover specific items where the exact selection hasn’t been made at contract time—such as tiles, taps, or appliances. These are estimated based on standard selections, and any variations will be costed separately if upgrades are chosen.
  3. Provisional Sums
    These are budget estimates for works that cannot be precisely defined before construction begins—such as site works, excavation, or landscaping. Builder Brokers works with you to minimise surprises by using accurate site assessments early on.
  4. GST (Goods and Services Tax)
    All pricing provided in our fixed price turnkey contracts includes GST. This ensures full financial transparency and compliance with Australian tax regulations.
