Complete Cost Breakdown — What You’re Actually Paying For

1. The Structure Itself

This is the base price quoted by your builder — the dwelling itself including walls, roof, windows, doors, bathroom and kitchen fitout. Always confirm exactly what is included. Common exclusions from base prices include flooring, appliances, airconditioning, solar systems, rainwater tanks and external paintwork. For kit home prices specifically, see our kit homes guide.

2. Site Preparation

Site preparation costs vary enormously by block: $5,000–$15,000 for a flat, clear, accessible block up to $40,000–$80,000 for a steep, remote, or flood/cyclone-affected site requiring specialised foundations. In North Queensland flood zones, elevated stumps or piering can add $20,000–$50,000 to a project that would be simple elsewhere.

3. Approval and Certification Costs

Approval costs vary significantly by state. As a general guide, budget $2,000–$10,000 for approvals on a straightforward project, and significantly more if a full Development Application or specialist assessments are required. See our state-by-state laws guide for exact figures per state.

4. Utility Connections

Grid electricity connection: $3,000–$15,000 within 100m of a power pole, rising to $30,000–$80,000+ for remote rural connections. Town water connection: $2,000–$8,000. Council sewer: $3,000–$12,000. For off-grid properties, see our off-grid setup cost guide.

5. Delivery and Installation (Transportable/Modular)

For modular and transportable homes, transport from factory to site and crane costs are separate from the build price. Within the same state: $2,000–$5,000. Interstate: $6,000–$15,000+. See our portable homes buyer’s guide for a full breakdown of what to include in your quote.

6. Climate-Specific Engineering

  • Cyclone engineering (North QLD/NT Darwin) — $1,500–$4,000 for engineering certification, plus additional material costs for Wind Region C/D compliance
  • NatHERS 7-star rating (VIC/NSW) — $500–$1,500 for the assessment, plus design changes if not achieved first pass
  • BAL assessment (bushfire prone areas) — $500–$2,000 for assessment, plus material upgrades depending on rating
  • BASIX certificate (NSW) — $500–$1,500

Hidden Costs Most Buyers Miss

  • Landscaping and access road — $2,000–$20,000 for a rural or acreage site
  • Insurance during construction — confirm builder’s insurance covers the build before signing
  • Stamp duty — payable on land purchase; check first home buyer concessions in your state
  • Contingency — always budget 10–15% of total project cost for variations and unexpected site costs
