Why Extend Your Home in Stanmore NSW?
Stanmore was ranked Sydney’s most in-demand suburb for 2024, celebrated for its heritage charm, village-like atmosphere, and unbeatable Inner West location. With the median house price exceeding $2.2 million, upgrading to a new home often means spending more for less.
That’s why so many Stanmore homeowners are choosing to extend rather than relocate. A well-planned home extension lets you create the space your family needs—whether it’s an extra bedroom, a second storey, or an open-plan living area—without leaving the suburb you love.
Even better, extensions not only improve functionality but also boost your property’s long-term value, especially in high-demand areas like Stanmore. And with its strong architectural identity and council heritage overlays, working with a local specialist ensures your extension enhances both your lifestyle and your home’s character.

Frequently Asked Questions About Home Extensions
1. How much does a home extension cost in Stanmore?
In Stanmore and surrounding Inner West suburbs, home extension costs typically range from $150,000 to $500,000+, depending on the size, complexity, materials, and whether it’s a single or second-storey build.
According to Archicentre Australia, average building costs in Sydney range from $3,000 to $4,000 per sqm for ground-level extensions and up to $4,000–$5,500 per sqm for second-storey additions, especially where structural or heritage complexities exist.
2.Do I need council approval for a home extension in Stanmore?
Yes, in most cases. Stanmore falls under the Inner West Council, which requires either a Development Application (DA) or Complying Development Certificate (CDC) for most extensions.
At Inner West Home Extensions, we manage the entire approval process—ensuring your design meets local planning controls, heritage overlays, and zoning regulations. This step typically takes 4–8 weeks, depending on the type of approval.
3.How long does a typical extension project take?
Most home extensions in Stanmore take 3 to 6 months from start to finish, depending on the project scale and weather conditions.
Design + Approval: 1–2 months
Construction Phase: 3–5 months
Heritage properties may require additional planning time, especially when structural work or façade changes are involved.
4.Can I live in my house during the extension?
Yes, in many cases you can remain in your home during construction—especially with rear or second-storey extensions where work zones can be isolated.
We use clear staging plans, dust barriers, and safety measures to minimise disruption. However, for more invasive work (e.g. full internal renovations), we’ll provide realistic advice on whether temporary relocation is recommended.
5.Will a home extension increase my property’s value?
Absolutely. A well-designed extension can significantly increase your home’s market value in Stanmore.
According to CoreLogic, properties with updated layouts, additional bedrooms, and open-plan living areas can see a 15% to 30% boost in resale value—especially in high-demand areas like Stanmore where median home prices exceed $2.2M.
Buyers in this area prioritise space, functionality, and preserved heritage character, making thoughtful extensions a smart long-term investment.
