Double Storey Extension Types

Craft Built Homes builds double storey extensions to suit different blocks, budgets, and households. The right scope depends on your existing structure, your council, and what you actually need the extra space for. Every project starts with a site assessment and council overlay check before any design work begins.

  • Full Second Storey Addition

    Adds a complete upper level to your home. Best suited to inner-east blocks where land is too valuable to build out. Requires a structural assessment of your existing slab and frame before design begins.

  • Partial Second Storey Addition

    Extends above part of the existing footprint rather than the whole home. A practical option when you need two or three extra rooms without the cost or complexity of a full upper level.

  • Second Storey With Master Suite

    The most common request. A dedicated upper level master bedroom with ensuite and walk-in robe, separate from the rest of the household. Gives the home a clear split between adult and family living.

  • Second Storey With Multiple Bedrooms

    Adding two, three, or four bedrooms above the existing ground floor. Suited to growing families who need the bedroom count without giving up the backyard or the suburb.

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.
