Double & Second Storey Extensions Melbourne
Cameron Construction designs and builds double storey and second storey extensions across Melbourne, managing design, engineering, permits and construction from concept through to completion.
Add More Space Without Losing Your Backyard
A second storey extension can add substantial living space without sacrificing your backyard. It can create extra bedrooms, bathrooms, living areas or a parents’ retreat while allowing your family to stay in the home and neighbourhood you already know.
Building upward requires careful planning. The existing structure, staircase location, roof removal, services, overlooking, neighbourhood character and council requirements all need to be considered before the design is finalised.
Cameron Construction manages the complete process, including design development, structural engineering, permit coordination and construction. Where building upward is not the best option, we can also assess other home extension options.
Why Build a Second Storey?
- Add substantial floor area without reducing your backyard
- Create extra bedrooms, bathrooms and flexible living zones
- Improve separation between children’s and parents’ areas
- Stay in your existing home and neighbourhood
- Design the new level to complement the existing house
Designed for Melbourne Homes
We work with a wide range of Melbourne housing styles, including Californian bungalows, period homes, weatherboards, brick homes and contemporary houses. Staircase position, bathrooms, services and the connection between the existing ground floor and new upper level are considered early so the finished home works as one.
For more detail on layouts, see our second storey extension floor plan guide.
Structural & Building Considerations
Before another level is added, the existing home needs to be assessed to determine how the additional loads will be supported. Depending on the dwelling, the design may require structural strengthening, new beams or columns, changes to load paths and alterations to the roof structure.
We coordinate the required design and engineering before construction begins and plan for practical issues such as roof removal, temporary weather protection, staircase placement, plumbing and electrical services, and how the new work connects to the existing home.
Our team also undertakes home renovations in Melbourne, allowing ground-floor alterations and the new upper level to be planned as one coordinated project.

Things to Consider When Building a Second Storey
A second storey extension affects more than the area directly above the existing home. Access, roof removal, weather protection, services and the way you use the house during construction all need to be considered as part of the build plan.
Whether you can remain in the home during the works depends on the scope and stage of construction. On some projects part of the home can remain usable, while on others moving out for a period may be safer and more practical.
FAQs
How much does it cost to add a second storey?
There is no single price that applies to every second storey addition. Cost is affected by the size and layout of the new level, structural work required to the existing home, bathrooms and services, staircase design, finishes, access and permit requirements. See our second storey extension cost guide for a more detailed breakdown.
Is it worth putting on a second storey?
It can be an excellent option when you need substantial additional space but want to retain your backyard and stay in your existing location. Whether it is the best solution depends on the structure of the home, planning constraints, the amount of space required and your project budget.
Do you need planning permission for a second storey extension?
A building permit is required for structural building work such as a second storey extension. A separate planning permit may also be required depending on the property, planning zone, overlays and the proposed design. We assess the relevant requirements during the design stage and can coordinate the consultants and approvals needed for the project.
Can I live in my home during a second storey extension?
Sometimes. Whether the home can remain occupied depends on the scope and stage of construction, including roof removal, weather protection, services and access. On some projects part of the home can remain usable; on others moving out for a period is the safer and more practical option. This is considered during pre-construction planning.
