House Extension Cost in Melbourne – What to Expect with Amcon Homes
If you love your location but need more room to grow, a home extension is one of the smartest and most cost-effective ways to upgrade your lifestyle. At Amcon Homes, we help homeowners understand the true house extension cost in Melbourne while delivering high-quality construction tailored to your needs, budget, and vision.
What Determines House Extension Cost in Melbourne?
The cost of extending your home can vary widely. Key factors include:
1. Extension Size and Floor Area
The larger the extension, the more materials, labour, and structural work required.
2. Type of Extension
Different extension types come with different cost ranges:
- Ground-floor room additions
- Second-storey extensions
- Garage conversions
- Kitchen and bathroom extensions
3. Structural Complexity
Costs increase when projects include:
- Removing load-bearing walls
- New plumbing or electrical systems
- Expanding wet areas like kitchens and bathrooms
4. Finishes, Fixtures & Custom Features
Premium flooring, custom cabinetry, designer fittings, and high-end finishes influence the final price.
5. Site Conditions
Sloping blocks, tight access, and drainage issues can affect construction time and labour.
Understanding these cost drivers early helps you budget confidently and avoid unexpected expenses.
Typical House Extension Cost in Melbourne
While every project is unique, Melbourne homeowners can generally expect:
Ground-Floor Extensions
$2,500 – $4,000 per m²
Second-Storey Extensions
$3,000 – $4,500 per m²
Kitchen & Bathroom Extensions
Allow additional budget for:
- Plumbing
- Electrical upgrades
- Waterproofing
- Custom cabinetry
- High-end appliances or fixtures
These areas require specialist trades, making them higher-cost zones within the home.
Why Invest in a Home Extension?
A well-planned extension can dramatically enhance your home’s:
- Living space and comfort
- Functionality for growing families
- Long-term property value
- Appeal in Melbourne’s competitive property market
Rather than buying and moving, extending gives you more space and lets you stay in the neighbourhood you love.
