Worked examples, not forecasts

Yields, returns, build costs, rents, ROI percentages, payback periods, refinance outcomes, and "before / after" comparisons shown in guides, articles, and marketing materials are illustrative examples based on past PremiumRea transactions or standard scenarios. They are not projections of what any particular property will achieve for any particular investor. Actual outcomes depend on purchase price, loan structure and interest rate, renovation cost, vacancy, maintenance, council rates, land tax, insurance, depreciation, personal tax position, and broader market movements — none of which are guaranteed.

Land Requirements for Subdivision

2-lot subdivision:

Standard block: 600m²+ required
Corner block: 500–550m² (corner blocks have dual street access, reducing minimum size)
Frontage: 19m is the golden number — allows retention of front house plus rear access

3-lot subdivision:

800–900m²+ required
Wider frontage needed for multiple driveways
Corner blocks are ideal for 3-lot configurations

Side driveway: Must be >3m wide for dual driveway access

Critical checks before buying:

Single Dwelling Covenant: Eliminates ALL subdivision potential. Removal costs $30K–$50K via VCAT with no guarantee of success — 6+ months process.
Central sewer easement: If the sewer runs through the middle of the block, subdivision is usually impossible without costly rerouting (~$60K)
Zoning: GRZ (General Residential) preferred. NRZ (Neighbourhood Residential) is more restrictive. RGZ (Residential Growth) is premium — allows highest density.
Heritage Overlay: Level 1 = avoid. Level 2 = best opportunity (front facade protected but rear extensions allowed).

Subdivision Costs & Timeline

Pure subdivision (paperwork only — sell vacant lot):

Council/surveying/planning costs: $30,000–$50,000
Sewer re-routing (if needed): Additional $60,000
Timeline: 12–15 months standard
Fast-track option: 10 days for qualifying subdivisions (recent policy)

Subdivision + rear house construction:

Subdivision costs: $30K–$50K
Single-storey house construction: ~$2,000/m² (150m² = $300K)
Total additional investment: $330K–$350K

Profit case study (Narre Warren):

Purchase: $670K (large-block old house)
Subdivision + rear build: $250K construction + $50K subdivision = $300K
Total cost: $970K
Front house sale: $520K–$550K
Rear house sale: $650K
Total revenue: $1.17M
Net profit: ~$200K

Zero-capital-down play:

Spend $50K on subdivision paperwork only
Sell the rear vacant lot: $250K–$350K
Instantly recoup your entire property deposit AND subdivision costs
Keep the front house as a rental

Best Suburbs for Subdivision

The ideal subdivision suburbs have large blocks, appropriate zoning, and strong end-sale demand:

Eastern suburbs (highest profit per lot):

Boronia: 700–800m² blocks common, GRZ zoning, $700K–$850K entry
Croydon: Similar profile to Boronia, slightly higher entry price
Bayswater: Corner blocks with three-way split potential
Ringwood: Premium location, highest end-sale prices

Southeast suburbs (best entry price):

Narre Warren: established subdivision precedent in the area, large blocks available
Cranbourne: Larger lots at lower entry prices
Hampton Park: Entry-level subdivision opportunities

Key factors for suburb selection:

Recent vacant land sales: Calculate $/m² for rear lots in the area — this determines your profit
Demand for new builds: Areas with young families drive new-build demand
Council attitude: Some councils are more subdivision-friendly than others
Infrastructure proximity: Near schools, transport, and shopping = higher end-sale price

Land value calculation method:

Find recent vacant land or knockdown-rebuild sales in the target suburb
Calculate per-m² rate
Multiply by your property's land area
Example: 845m² block at $1,230/m² land rate = land value ~$600K

Frequently asked questions

How much land do I need to subdivide a block in Melbourne?

A 2-lot subdivision generally needs a standard block of 600m²+, or 500 to 550m² on a corner block because dual street access reduces the minimum. Frontage of 19 metres is the golden number, as it allows a workable dual driveway. A 3-lot subdivision needs 800 to 900m²+ with wider frontage for multiple driveways, and corner blocks are ideal.

What should I check on the title before buying a block to subdivide?

A Single Dwelling Covenant eliminates all subdivision potential and costs $30K to $50K to attempt to remove through VCAT over 6+ months with no guarantee of success. Easements and sewer alignment matter too — you cannot build over a sewer line. The side driveway must be wider than 3 metres for dual driveway access.

How much does a subdivision cost in Melbourne and how long does it take?

A pure paperwork subdivision where you sell the vacant lot costs $30,000 to $50,000 in council, surveying and planning fees, with a standard timeline of 12 to 15 months. Sewer re-routing where needed adds around $60,000. Adding a rear house at roughly $2,000 per square metre — $300K for 150m² — takes the total additional investment to $330K to $350K.

Can you show a real subdivision profit example?

The Narre Warren case on this page: a $670K purchase of a large-block old house, plus $250K of construction and $50K of subdivision costs, for a $970K total. The front house and the newly created rear lot were then sold separately. The profit depends entirely on the end-sale values in that specific suburb at that time, which is why the vacant-land comparable is the number to check first.

What is the zero-capital-down subdivision play?

Spend around $50K on subdivision paperwork only, sell the rear vacant lot for $250K to $350K, and you have recovered the property deposit and the subdivision cost while keeping the front house. Whether the rear lot achieves that range depends entirely on recent vacant land sales in the suburb — check them before you buy, not after.

How do I work out what a rear lot is worth before I buy?

Find recent vacant land or knockdown-rebuild sales in the target suburb, calculate the per-square-metre rate, and multiply by the land area you would create. That per-m² rate, and the demand for new builds in the area, are the two variables that decide whether a subdivision works — not the size of the block on its own.

Which Melbourne suburbs are best for subdivision?

The eastern suburbs give the highest profit per lot: Boronia with 700 to 800m² blocks common, GRZ zoning and $700K to $850K entry, and Croydon with a similar profile at a slightly higher entry price. The southeast gives the best entry price: Narre Warren has established subdivision precedent, and Cranbourne and Hampton Park offer larger lots at lower entry.

What determines whether a suburb suits subdivision?

Three things: recent vacant land sales that establish a $/m² rate for rear lots, genuine demand for new builds from young families or downsizers, and zoning plus block geometry that physically permits the split. A large block in a suburb with no vacant-land market gives you a lot you cannot sell.
