House Extensions Melbourne
Love your street, need more house? YoungConstruct designs and builds house extensions across Melbourne's east, from ground-floor additions to second storeys, managed end-to-end by a licensed builder.
Melbourne house extensions, built properly
An extension is the biggest build most homeowners ever take on: design, permits, engineering, foundations, framing and weatherproofing all have to be sequenced properly, and tied seamlessly into your existing home.
That's why every YoungConstruct extension is managed end-to-end by a registered building practitioner with structural carpentry at the core: one point of contact from concept and permits through to the final coat of paint.
Every type of extension, one builder
The right extension depends on your block, your budget and your council. We design and build all of them, and tell you honestly which suits your home.
Ground-floor extensions
Extend out into your block: bigger living areas, new bedrooms or an open-plan kitchen and dining zone.
Second-storey additions
Double your footprint without losing backyard: structural engineering and framing handled in-house.
Sunrooms & living extensions
Light-filled rooms that connect indoor living to the garden, built weathertight for year-round use.
Seamless integration
Rooflines, cladding and interiors matched to your existing home, so it never looks like an add-on.
Permits and engineering handled for you. Because YoungConstruct is a registered building practitioner (DB-L 100172), planning, building permits, engineering and inspections are all coordinated by us, not left for you to chase.

House extension FAQs
How much does a house extension cost in Melbourne?
It depends on the size, whether you build out or up, and the finishes you choose. Second-storey additions cost more per square metre than ground-floor extensions due to structural work. After a free on-site visit we provide a detailed, itemised quote before any commitment.
Do I need a permit for a house extension?
Yes, extensions require a building permit and sometimes a planning permit depending on your council and block. We coordinate all permits, engineering and inspections for you as part of the project.
How long does a house extension take?
Most extensions take 3–6 months of construction depending on size and complexity, plus design and permit time upfront. You receive a clear schedule before work begins.
Can we live in the house during the build?
Usually, yes. Most extensions are staged so your existing home stays weathertight and liveable, with the new section only opened up to the house near the end of the build.
Is it better to extend or move?
For most families, extending wins financially: moving costs $75k–$135k+ in stamp duty, agent fees and moving costs, money you never see again. An extension puts that same money into your own home and adds resale value.
