What a renovation
costs in Armadale
Armadale is tighter than its Stonnington neighbours — Victorian terraces and villas on narrower allotments, with heritage coverage across most of the older streets. The budgets are high but the sites are constrained, and constraint is what actually costs money.

What drives cost here
Narrow allotments
Terraces and semi-detached villas frequently have no way to get machinery to the rear. Materials go through the house, and that is measured in labour weeks rather than material cost.
Heritage across the older streets
Stonnington overlays are extensive here. Rear additions are usually achievable; anything that reads from the street is a harder conversation.
Party walls
Terraces share structure with neighbours. Protection works, dilapidation surveys and negotiated agreements are standard, and they precede any construction.
High land value pushes work upward
With limited room to extend outward, Armadale projects often go up. Second storeys carry both the structural premium and the heritage visibility problem.
Typical Armadale projects
| Project | Why it costs what it does | Range |
|---|---|---|
| Rear extension to a Victorian terrace | Small in area, expensive in delivery. Access and party-wall protection carry much of the cost. | $335k – $455k |
| Second storey behind a retained facade | Structural upgrade below plus heritage-sensitive design above. | $535k – $725k |
| Whole-house renovation | Services replacement through a constrained site with restricted access. | $995k – $1345k |
| Bathroom only | Below our minimum — referred to a single trade. | $30k – $55k |

Common questions
Why does a small Armadale extension cost so much?
Because you are paying for delivery rather than floor area. Restricted access, party-wall protection and heritage approval are largely fixed costs that do not scale down with the size of the addition.
Do I need agreements with neighbours for a terrace extension?
If you share a party wall or work near the boundary, almost certainly. Protection work notices and dilapidation surveys are standard on terraces and far cheaper to arrange before work starts than to argue about afterwards.
Is Armadale more expensive than Malvern to renovate?
Per square metre, usually yes, despite Malvern houses often being grander. Armadale sites are more constrained, and site constraint drives construction cost more directly than house size does.
What is not included in these ranges?
Landscaping and external works, appliances, furniture and window furnishings, council planning application fees, driveway reinstatement, and anything found once walls are opened. Design fees, engineering, building surveyor, permit levy and energy assessment are included.

We are paid a fee by them on work that proceeds, and you are under no obligation to use them.
