Home Extensions

Melbourne

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 can't fit everyone at Christmas, it stopped working.

A well-designed home extension in Melbourne gives your family the space it needs without uprooting your life.

At LiLAC, we design and build home extensions that feel like they were always meant to be there, not an obvious add-on, but a natural continuation of your home. Whether it's a second storey addition, rear extension, or a complete ground floor reconfiguration, our approach stays the same: fixed-price contracts, one dedicated team and a carefully managed process from start to finish.We manage everything — structural engineers, planning permits, construction and final handover. You focus on your life. We handle the rest.

PROCESS
Initial Consultation:
We start by understanding how your family actually uses your home, what's working, what isn't, and what you want to change. Before anything is designed or quoted, we listen.
Site Assessment & Feasibility:
We assess your existing home and site in detail — structural considerations, council overlays, heritage requirements and what's genuinely possible within your space. Honest advice before anything moves forward.
Design & Planning:
We work with your architect or connect you with trusted partners to design an extension that feels seamless and thoughtfully integrated with the existing home. We also guide you through key finishes and design decisions early — so the new spaces feel cohesive and there are no surprises once construction begins.
Fixed Price Contract:
A fixed-price contract, not an estimate. The number we agree on is the number you pay, no variation shocks, no budget surprises. Complete clarity before construction begins.
Construction:
One dedicated project manager oversees every stage — structural work, trades coordination, materials and finishes. Fortnightly updates throughout so you always know exactly what's happening on site.
Completion & Handover:
A final walkthrough together to ensure every detail is exactly right. We don't consider a project finished until you're completely happy with the result.

FAQs
How much does a home extension cost in Melbourne?
Every extension is different, the scope, size, structural requirements and finishes all shape the final investment. We don't do ballpark figures. We provide detailed, fixed-price quotes built entirely around your specific project, so you know exactly what you're investing before anything begins.
How long does a home extension take?
It depends on the scope and complexity. A rear extension typically takes 4–6 months after permits, while a second storey addition can take 8–12 months. We provide a detailed timeline from the start and keep you updated every fortnight.
Do I need council approval for an extension?
In most cases, yes, particularly for second storey additions, extensions that affect the building envelope, or properties with heritage overlays. Our team manages the entire approvals process and guides you through every requirement specific to your suburb and site.
Can I stay in my home during the extension?
In most cases, yes, though there will be periods of disruption depending on the scope of work. We plan construction stages carefully to minimise impact on your daily life and keep you informed of what to expect at every step.
What if my home has a heritage overlay?
Heritage overlays are something we know well across Melbourne's inner suburbs. We understand what councils require, how to design sensitively within heritage guidelines, and how to deliver a result that respects your home's character while adding modern functionality.
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.
