What a renovation
costs in Richmond
Richmond is workers cottages and terraces on small allotments, heritage precincts through most of the older streets, and a former industrial history that occasionally surfaces during excavation. It is a constrained suburb with strong budgets — an expensive combination.

What drives cost here
Small cottages, tight sites
The classic Richmond block is narrow with no side access. Materials move through the house, and the labour cost of that dwarfs the square metres you are adding.
Former industrial land
Richmond was a manufacturing suburb. Pockets carry contamination history and fill of unknown quality. A soil report early costs a fraction of a mid-excavation discovery.
Richmond Hill topography
The land around the hill falls away sharply. Slope means deeper footings, retaining and engineered drainage before anything visible begins.
Yarra heritage precincts
Coverage across most of the older grid. Rear additions are usually workable; street-visible changes attract genuine scrutiny.
Typical Richmond projects
| Project | Why it costs what it does | Range |
|---|---|---|
| Rear extension to a workers cottage | Small in area, expensive in delivery. Access and heritage carry most of the cost. | $310k – $415k |
| Second storey over a cottage | Original footings rarely carry a new floor without substantial upgrading. | $505k – $680k |
| Whole-house renovation | Services replacement through a small constrained footprint. | $880k – $1190k |
| Bathroom only | Below our minimum — referred to a single trade. | $28k – $50k |

Common questions
Is contamination a real risk in Richmond?
In the former industrial pockets, yes, and it is worth checking rather than assuming. A soil report early in the process costs far less than a discovery mid-excavation, and it lets a builder price the job properly instead of loading the quote with contingency.
Why does a small Richmond extension cost as much as a larger suburban one?
Access, heritage approval and party-wall protection are largely fixed costs. They do not scale down with the size of the addition, so a 35 square metre job carries much of the same overhead as a 50 square metre one elsewhere.
Can I put a second storey on a workers cottage?
Structurally usually yes, with enough work. Original cottage footings rarely carry a new floor without substantial upgrading, and that work sits under the floor where you will never see it. Get an engineer to look before you commit to a design.
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.

When you are ready to build
AE Index is not a building company. When a project is ready to be priced properly, we pass it to a builder from our verified network — who will walk the site, inspect what is under the floor, and put a fixed price in writing. We are paid a fee by them on work that proceeds, and you are under no obligation to use them.
- Current domestic builder registration, confirmed with the Victorian Building Authority
- Domestic building insurance current and sighted
- Two completed projects contacted directly — not supplied testimonials
- Fixed-price contracts with a written variations policy
