Most Melbourne homeowners choose to extend for one of three reasons: the family has grown, the layout no longer works, or they love the suburb too much to leave. Craft Built Homes builds home extensions that solve the actual problem, more space, better flow, or both, without the disruption of moving.

We work across Melbourne's inner east and north-eastern suburbs, including Doncaster, Kew, Balwyn, Templestowe, and Warrandyte. Our focus is on extensions that integrate with the existing home, not ones that look like something was bolted on.

Home Extensions Across Melbourne's Inner East

Craft Built Homes builds home extensions across Melbourne's north-eastern and inner-east suburbs Manningham, Boroondara, Nillumbik, and Whitehorse council areas. Our site managers work and live locally, which means real knowledge of council overlays, permit processes, and site conditions in each area.

  • Craft Built Homes completed home extension project in Doncaster, Melbourne

    Manningham Council

    Doncaster & Templestowe

    Manningham Council applies consistent ResCode requirements. Most extensions in this area are assessed under Victoria's standard residential provisions, though Heritage Overlay applies to some pockets near Doncaster Road. We know the process well.

  • Craft Built Homes completed home extension project in Kew, Melbourne

    Boroondara Council

    Kew & Balwyn

    Boroondara Council is one of Melbourne's more rigorous planning environments. Second storey additions here often require a planning permit regardless of size. We factor approval timelines into every Boroondara quote.

  • Craft Built Homes completed home extension project in Eltham, Melbourne

    Nillumbik Council

    Eltham & Warrandyte

    Nillumbik's bushfire overlay (BAL ratings) affects construction specifications in these areas. If your property is in a designated zone, we'll identify this in the initial site review and spec accordingly.

  • Craft Built Homes completed home extension project in Hawthorn, inner east Melbourne

    Boroondara & Whitehorse Councils

    Inner East Generally

    Camberwell, Hawthorn, Surrey Hills, and Box Hill all have a mix of period homes and contemporary builds. Extensions in these areas typically need to address neighbourhood character guidelines from Boroondara and Whitehorse councils.

Melbourne Home Extension Types

Craft Built Homes builds five types of home extensions across Melbourne's inner east and north-eastern suburbs. The right solution depends on your block size, existing structure, local council requirements, and how you use your home.

  • Ground Floor Extensions

    The most common request. Expanding the rear of the home to create a larger kitchen, open-plan living area, or additional bedroom. Works on most standard Melbourne blocks and typically involves fewer council constraints than going up.

  • Second Storey Additions

    Adds significant space without touching the backyard. Best suited to homes on smaller blocks in inner-east suburbs where land is too valuable to build out. Requires a structural assessment of your existing slab and frame before design begins.

  • Rear Extensions With Indoor-Outdoor Connection

    Extending the back of the home and opening it to an outdoor entertaining area or courtyard. One of the highest-return improvements for Melbourne resale value, particularly in Boroondara and Manningham council areas.

  • Open-Plan Conversions With Extension

    Removing internal walls and extending at the same time. Gives you the layout change and the extra square metres in one project with one builder.

  • Additional Rooms

    Bedrooms, bathrooms, home offices, or multipurpose spaces added to the side or rear. Often permitted under Victoria's ResCode without a full planning permit, depending on height and setbacks.

  • No Scope Creep. No Surprises.

    Every project goes through the same process: site assessment, council overlay check, realistic scope discussion, then build. What we quote is what you pay.

FAQs About Home Extensions

How much does a home extension cost in Melbourne?

Costs depend on scope, materials, structural complexity, and whether planning permits are required. As a rough guide: a single-room ground floor addition typically starts from $80,000–$120,000+. A full rear extension with open-plan living starts from $150,000+. A second storey addition starts from $200,000+. These are starting points your actual quote depends on your site, your council, and your brief. We give honest cost expectations in the first consultation.

How much do home renovations in Melbourne cost?

Yes. Most home extensions in Melbourne require both a planning permit and a building permit from your local council. Heritage overlays and height restrictions may also apply depending on your suburb. Craft Built Homes manages the full approvals process as part of every extension project.

How long does a home extension take?

A standard single-room extension typically takes a few months. A second storey addition or full rear extension will take longer depending on scope and council approvals. You will get a realistic schedule upfront, not estimates that shift once the build starts.

What types of home extensions do you build?

Ground floor extensions, second storey additions, rear extensions with indoor-outdoor connection, open-plan conversions, additional bedrooms and bathrooms, and home office additions. Every project is designed to integrate with the existing home, not look like it was added afterward.

Is it cheaper to extend or move house?

For most Melbourne homeowners in the inner east, extending is significantly cheaper than selling, paying stamp duty, and buying a larger property in the same suburb. A well-scoped extension also adds measurable resale value. Additional bedrooms, better indoor-outdoor flow, and expanded living areas are features Melbourne buyers pay a premium for.

Will a home extension add value to my property?

Yes. A well-built extension typically returns strong value in Melbourne's inner-east market. Adding a bedroom takes a 3-bed to a 4-bed, one of the most significant price bracket shifts in residential property. Expanding living areas and improving indoor-outdoor connection are also high-return improvements in suburbs like Doncaster, Kew, and Camberwell.

Can I build a second storey addition on my home?

Yes, subject to your block, existing structure, and council requirements. We assess your slab, frame, and council overlays before any design work begins. Second storey additions are common in inner-east suburbs where land is too valuable to build out, they're one of the most effective ways to add meaningful space.

Do you build home extensions in Doncaster and the north-eastern suburbs?

Yes. Doncaster and Templestowe are among our most active areas. We understand Manningham Council's assessment process, local ResCode applications, and the construction requirements specific to homes in the area. See our Doncaster builder page for more detail.

Do I need a planning permit for a home extension in Melbourne?

Most home extensions in Melbourne require a building permit. A planning permit is required if you're in a Heritage Overlay, if the extension exceeds certain height or setback limits under ResCode, or if your local council has specific neighbourhood character requirements. Craft Built Homes manages the full permits process and will identify what's required for your specific property before any design work begins.
