What affects the cost of building a new house?
The total cost of constructing a new home depends on several factors. Key considerations include:
- Home size: Larger floor plans require more materials and labour, naturally increasing costs.
- Construction type: Choosing between timber frame, brick veneer, or other structural systems impacts pricing.
- Number of storeys: Adding a second level generally increases the cost by 5–10% due to extra materials and engineering requirements.
- Materials and finishes: Premium fixtures, custom cabinetry, and high-end finishes can significantly raise costs.
- Site conditions: Sloping blocks, poor soil, or limited access can increase excavation and preparation expenses.
- Builder selection: Costs vary between large-scale volume builders and smaller custom home builders.

Construction cost trends in 2026
Building costs have moderated significantly in 2026 after the surges of 2021–2024. H1 2026 data shows national cost growth of 2–3%, down from 8–12% annual increases during the post-pandemic period.
- Labour: Skilled trade shortages persist but wage growth has slowed to 3–4% annually.
- Materials: Timber, concrete, and steel prices have stabilised. Steel slightly down from 2025 highs.
- Supply chain: Import lead times have normalised. Custom items may still carry 4-to-8-week lead times.
- Regional: Brisbane and Perth seeing near-flat cost growth. Sydney and Melbourne remain elevated.
2026 presents a more predictable building environment than recent years — making it a reasonable time to proceed if land and budget permit.

Preparing for builder quotes and contracts
Before requesting quotes, it’s important to have your plans finalised and a clear idea of your materials and finishes. The more detail you can provide upfront, the more accurate and comparable your quotes will be.
When gathering quotes, aim to compare several builders to understand market rates and inclusions. Once you’ve chosen a builder, a written contract is required to formalise the agreement and protect both parties.
What your contract should include
- Scope of work: A clear outline of what’s included in the build
- Total cost: The agreed price, including allowances and exclusions
- Timeline: Estimated start and completion dates
- Payment schedule: When payments are due throughout the build
- Dispute resolution: How any issues will be handled
Common contract types
- Fixed-price (lump sum): A set total cost for the project
- Cost-plus: Actual costs plus the builder’s margin
- Hybrid/standard: A combination of fixed and variable pricing
Choosing the right contract and understanding exactly what’s included helps avoid unexpected costs and keeps your project on track from start to finish.
Check out builders in Sydney, Melbourne, Brisbane, Perth or Adelaide to compare quotes.
