A home extension in Kew is a planning problem first. Boroondara City Council setbacks, overlays and neighbour amenity sit in front of the kitchen or living room you want to add.
This living extension guide is for family period homes and 1930s brick houses — the stock that decides whether a rear push, side infill or second storey is the cheaper path.

When an extension beats a full rebuild in Kew
Keep the street face if the house still works. Extend where the living actually fails — usually the rear of family period homes and 1930s brick houses.
- Rear extensions protect street character.
- Second storeys need structure, stairs and overlay advice.
- A kitchen-only bump can be enough if the rest of the house is sound.
Boroondara City Council and the approval path
Boroondara City Council will look at setbacks, site coverage, overshadowing and, in many Kew streets, heritage or neighbourhood character. A builder who prices without that conversation is guessing.

How an extension joins the existing Kew house
The expensive line is the junction: floor levels, roof pitch, thermal break and how the old kitchen dies into the new volume. Kew period homes punish lazy junctions.
Budget logic for Kew additions
Price structure, envelope, services and the refurbished old rooms as four packages. An extension that ignores the existing kitchen still leaves you with a broken house.

A few more answers
Questions about your next step.
Do I need a permit for this work in Kew?
Boroondara City Council and the Victorian Building Authority decide it. Layout changes, wet-area work and extensions are the usual triggers. Confirm before demolition.
How long does a Kew project usually take?
Same-footprint rooms are weeks on site. Extensions and full-home programmes run to months because joinery, stone and approvals sit in front of the visible build.
Can VicWide work in Kew?
Yes. We measure family period homes and 1930s brick houses across Melbourne and write a fixed scope after the site visit, not over the phone.
