Ground Floor, Second Storey & More.
Need more space without moving? We design and build home extensions across Melbourne's northern suburbs. Fixed price, permit managed, one builder start to finish.
Ground Floor Extensions
Extend your living area, add a bedroom or open up to a new kitchen-dining space at the rear or side of your home.
Second Storey Extensions
The ideal solution when you love your street but need more floor space — maximise without losing your backyard.
Rear Extensions
Melbourne block sizes suit rear extensions well. Open up the back of the home to create connected indoor-outdoor living.

01
Do I need a planning permit for a home extension in Melbourne?
Not always. Many extensions under ResCode provisions proceed with a building permit only. Whether planning approval is needed depends on the size, setbacks and your specific property. We assess this as part of the free consultation.
02
How long does a home extension take?
Most extensions take 3–6 months from permit approval to handover. Allow additional time for design, documentation and the permit process typically 2–4 months.
03
Can we live in the house during the extension?
Usually yes for ground floor additions, though some disruption is inevitable. Second storey additions are more complex we'll advise based on your specific project.
04
How much does a second storey addition cost?
Second storey additions in Melbourne typically range from $250,000–$500,000+ depending on size and specification. See our Home Extension Cost Guide page for a full cost breakdown.
