About

Home Extensions
in
Melbourne

Home extensions in Melbourne dependss on scope, structural complexity, and finish level. For most Melbourne homeowners, extending is significantly cheaper than selling and buying in the same suburb when you factor in stamp duty, agent fees, and the price premium on larger homes.

Maybe your home is almost perfect. The street is right, the neighbourhood is right, the kids are settled. But somewhere between the home office that took over the spare room and the kitchen that cannot fit everyone at Christmas, it stopped working. A well-designed home extension gives your family the space it needs without uprooting your life.

At LiLAC, we design and build home extensions across Melbourne's Inner East and Bayside suburbs including Hawthorn, Kew, Camberwell, Brighton, and Malvern. Whether it is a second storey addition, rear ground floor extension, or a complete ground floor reconfiguration, the approach stays the same. Fixed-price contract, one licensed builder (BPC DB-U 100-151), structural engineers, planning permits, construction, and final handover all managed under one contract. A result that feels like it was always meant to be there, not an obvious add-on.

PROCESS
Pre-Construction
Every home extension in Melbourne requires a building permit before work begins. Many also require a planning permit, particularly in heritage overlay zones or where setbacks, height, or overshadowing limits apply. At LiLAC, the entire approvals process is managed on your behalf, including architectural documentation, structural engineering, council submissions, and permit coordination. Every material, finish, and structural decision is locked in before construction starts so there are no variations mid-build and no costs you did not agree to upfront.
Construction
Your home extension takes shape in the right sequence. Demolition, excavation, and foundations first, followed by structural framing, roofing, and weatherproofing before any internal work begins. Electrical, plumbing, and mechanical services roughed in and inspected before walls close. Internal lining, insulation, joinery, tiling, windows, and final fit-off coordinated across every trade under one licensed builder. One dedicated project manager on site throughout with fortnightly progress updates so you always know exactly where your home extension stands.
Handover
A home extension in Melbourne is only finished when every detail meets the standard you were promised. We complete a full walkthrough together before the space is handed over. All building compliance certificates, structural warranties, and documentation are handed to you directly. We do not consider the project complete until you do.

FAQs
How much does a home extension cost in Melbourne?
The cost of a home extension depends on your scope of work. The size of the addition, whether it is ground floor or a second storey, the finishes and any structural or roof changes all affect the figure. We assess your home and brief, then give you a clear fixed price after the design stage.
Do I need a permit for a home extension?
Usually yes. Most extensions need a building permit, and many also need a planning permit, especially for second storey additions or homes in a heritage overlay. We handle the full permit and council approval process for you, so you do not have to navigate it alone.
How long does a home extension take?
A typical home extension takes around 3 to 6 months on site, plus time beforehand for design, approvals and permits. Larger or second storey additions can take longer. We give you a clear schedule before work starts and manage the build from start to finish.
Can I live in my home during an extension?
Often yes. Because an extension usually adds to one part of the home, we can seal off the work zone and keep the rest of your house liveable. For larger second storey additions it may be easier to move out for part of the build. We plan this with you early.
Ground floor or second storey extension, which is better?
It depends on your block and needs. A ground floor extension suits homes with land to spare and avoids stairs, while a second storey adds space without losing yard, ideal on smaller Melbourne blocks. We assess your site, budget and lifestyle and recommend the smartest option.
Does a home extension add value?
Yes. A well designed extension that adds living space, bedrooms or a modern kitchen usually adds strong value in sought after Melbourne suburbs. The key is designing it to suit your home and area, which we factor in from the first concept so the addition feels seamless, not bolted on.
At Lilac Constructions, we work with homeowners across Melbourne's most established suburbs, the places where people have invested in their community and want a home that reflects that.

Our projects are concentrated in Melbourne's eastern and bayside suburbs, where we know the streets, the councils, and the character of each neighbourhood intimately.

If you're in Brighton, Hampton or Sandringham, looking out over the bay and imagining something better. In Kew, Hawthorn, Camberwell or Canterbury, where character homes sit alongside some of Melbourne's finest streets. In Malvern or Balwyn, where school catchments and lifestyle come together. Or further east in Ivanhoe, Doncaster, Templestowe or Warrandyte, where space meets proximity.

We also work across Richmond, Fitzroy, Brunswick and Northcote, suburbs where design-forward homeowners are reimagining what their homes can be.

We don't try to be everywhere. We choose to be exceptional where we are.

Zac and the team at Lilac built an undercover deck at my place and did an excellent job. The pricing was clearly outlined from the start with no surprises, the team were thoughtful and respectful while onsite, and the workmanship and attention to detail were outstanding. I’m extremely happy with the result and would highly recommend them.
