Construction Loans Guide

Everything You Need to Know About Building Your Dream Home

Building your own home is one of the most exciting journeys you can embark on. Unlike buying an established property, construction loans work differently - they're designed to fund your build in stages as construction progresses. Understanding how these loans work is crucial to ensuring your building project runs smoothly from foundation to completion.

Whether you're building on vacant land, knocking down and rebuilding, or completing major renovations, this guide will walk you through everything you need to know about construction financing in Australia.

How Construction Loans Work

Progressive Drawdowns

Unlike a standard home loan where you receive the full amount at settlement, construction loans release funds in stages as your build progresses. These stages typically align with key construction milestones, and you only pay interest on the amount drawn down at each stage. This means lower repayments during the construction phase.

The Five Standard Construction Stages

Stage 1: Deposit (5-10%)

Initial payment to secure your builder and begin site preparation

Stage 2: Base/Slab (15-20%)

Foundation and concrete slab completion

Stage 3: Frame (20-25%)

Structural framing, roof trusses, and external walls

Stage 4: Lock-up (20-25%)

External cladding, windows, doors, and roofing complete

Stage 5: Fixing & Completion (25-35%)

Internal fit-out, plastering, painting, flooring, and final touches

Land and Construction Packages

Many first-time builders opt for house and land packages, where you purchase vacant land and a building contract together. These packages can simplify the process significantly, as the builder handles most of the coordination. However, it's important to understand how the financing works:

Key Considerations

  • Land settlement typically occurs first, followed by construction drawdowns
  • Your deposit requirement is usually based on the combined value of land and construction
  • First Home Buyer grants and stamp duty concessions may apply differently
  • Building contracts should include fixed-price clauses to protect against cost blowouts

What You'll Need for Approval

Documentation Required

  • - Fixed-price building contract
  • - Council-approved plans and specifications
  • - Builder's licence and insurance details
  • - Land contract (if applicable)
  • - Detailed cost breakdown/schedule
  • - Standard income and ID documents

Builder Requirements

  • - Valid builder's licence
  • - Home warranty insurance
  • - Public liability insurance
  • - ABN registration
  • - Clean building history
  • - Fixed-price contract capability

Interest Rates and Costs

Construction loan rates are typically similar to standard variable home loan rates. During construction, you'll usually pay interest-only on the amount drawn down. Once construction is complete, the loan converts to a standard principal and interest home loan.

Additional Costs to Budget For

  • Council fees: Development applications, building permits, and inspections
  • Site costs: Soil tests, surveys, and site preparation
  • Connection fees: Water, electricity, gas, and sewerage
  • Landscaping: Driveways, fencing, and garden works
  • Contingency buffer: 10-15% for unexpected costs

Typical Construction Timeline

A standard residential build typically takes 6-12 months depending on the complexity of your design, weather conditions, and builder availability. Here's what to expect:

1-2

Weeks 1-2

Site preparation and slab pour

3-6
