Home extensions in Melbourne’s Eastern Suburbs
A home extension or building extension can add the space your family needs without leaving a street and neighbourhood you like. The new work should connect naturally with the existing house, with the layout, structure, approvals and construction planned as one coordinated project.
EBC is a registered Melbourne home extension builder. We deliver ground-floor and upper-level house extensions across Melbourne’s Eastern Suburbs, from the first design conversation through to handover, coordinating the new building work with the existing home as one project.
Types of building extensions we deliver
Ground-floor extensions
Rear or side additions that create more living space, larger kitchens, bedrooms or bathrooms while connecting with the existing ground floor.
Second-storey extensions
Upper-level additions that increase floor area without taking more of the backyard, subject to the existing structure, planning controls and engineering.
Rear and side house extensions
Building extensions planned around the block, setbacks, access, roof form, existing services and the way the new rooms connect to the home.
Extension plus renovation
Combine the new building extension with renovation work so existing rooms and the added space function as one coordinated home.

Building extension and home extension builder serving Melbourne’s Eastern Suburbs
EBC builds home extensions across Melbourne’s Eastern Suburbs, including Forest Hill, Ferntree Gully, Mitcham, Blackburn, Ringwood, Croydon, Boronia, Glen Waverley and Rowville. Projects can include ground-floor additions, upper-level extensions and building extensions combined with renovation work, with the existing home and new work planned as one coordinated project.
What affects the cost and timeline of an extension?
There is no single price for an extension, because every block and every house is different. The main factors are:
- ✓How much floor area you are adding, and whether it is single or multi-level
- ✓Site conditions, including soil, slope, access and existing structures
- ✓How the new area connects to the existing house
- ✓Design complexity and the finishes and fittings you choose
- ✓Approvals your project requires, such as building and, where relevant, planning permits
- ✓Any updates needed to the existing home so the old and new work together

Extension questions homeowners ask us
What is a building extension?+
A building extension adds new floor area to an existing home, such as extra living space, bedrooms, bathrooms or an upper level. The new work must be designed and built so it connects correctly with the existing structure, roof, services and approved plans.
What does a home extension builder manage?+
A home extension builder coordinates the construction of the new space and its connection to the existing house, including trades, site sequencing, structural work and quality control. The project also needs to align with the approved plans, engineering and permits that apply to the property.
Do I need a permit to extend my house in Victoria?+
Extensions almost always need a building permit, and depending on your property, setbacks and any overlays, may also need a planning permit. We will explain which approvals apply to your project as part of planning it.
How long does a home extension take?+
Design and approvals come before construction, and the build itself depends on the size and complexity of the extension. We will give you an expected timeline once we understand your project.
Can we live in the house while the extension is built?+
Often, yes. Much of the work happens outside or separately from the existing rooms, though there will be disruption, especially where the new space connects to the old. We will talk through what to expect.
Do I need plans drawn before I contact a builder?+
No. You can start by registering your project and working through our Home Design Tool, which helps us understand what you want before we talk.
How do I know what an extension will cost?+
We quote from your specific scope. Our guide on extension costs and timelines explains what drives the price, and a free consultation is the quickest way to get numbers that fit your home.
Which areas do you build extensions in?+
We work across Melbourne’s Eastern Suburbs, including Ringwood, Croydon, Boronia, Blackburn, Glen Waverley, Mitcham and Rowville. If you are nearby, register your project with your address and we will confirm we can help.
