FAQs About Home Extensions

How much does a home extension cost in Melbourne?

Every extension is different, but costs depend on the size, scope, materials, and whether structural or planning approvals are needed. A single-room ground floor extension sits at a different price point to a full second storey addition. Craft Built Homes gives you honest cost expectations in your first consultation no guesswork.

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?

Craft Built Homes builds ground floor extensions, second storey additions, open-plan living and kitchen extensions, additional bedrooms and bathrooms, and full rear extensions. Every project is designed to integrate with your existing home, not look like it was added on as an afterthought.

Is it cheaper to extend or move house?

For most Melbourne homeowners, extending is cheaper than selling, paying stamp duty, and buying again in the same area. A well-designed extension also adds significant resale value: extra bedrooms, expanded living areas, and better indoor-outdoor flow are all features Melbourne buyers pay a premium for.

Will a home extension add value to my property?

Yes. A well-built home extension increases both liveability and resale value. Adding a bedroom, expanding your living space, or improving indoor-outdoor connection are among the highest-return improvements you can make to a Melbourne home.

Can I build a second storey addition on my home?

Yes, provided your block, structure, and local council requirements allow it. Second storey additions are one of the most effective ways to add significant space without losing the backyard. Craft Built Homes assesses your existing structure and council overlays before any design work begins.

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

Yes. Craft Built Homes services Doncaster, Templestowe, Warrandyte, Eltham, and across Melbourne's north-eastern and inner suburbs. The team understands local council requirements, heritage considerations, and the architectural style of homes in these areas.
