St Albans Street-by-Street: Which Blocks Have Development Potential and Which Are Dead Ends

Two months ago I published a suburb analysis on St Albans — specifically the Carinlea pocket — and the response surprised me. Hundreds of messages. Mostly the same question in different words: "Can I subdivide there?"

Fair question. Because if you can buy a 650-square-metre block for $700K and split it into two lots, the development math changes dramatically. Two titles at $500K each is a $300K gross profit before costs. Even after subdivision fees ($15K-$20K in soft costs), council contributions, and building expenses, the upside is substantial.

But here's the thing most investors don't realise: not every 600sqm block in St Albans can be subdivided. Zoning varies street by street. Easement positions vary block by block. Access requirements mean some blocks are physically impossible to split regardless of what the zoning says.

So I went back to St Albans with our research team. We walked the streets, pulled the council planning maps, cross-referenced easement data from the titles, and built a pocket-by-pocket guide to development potential.

This is the result. It's specific. It's practical. And it might save you $700K in buying the wrong block.

Zoning 101: GRZ vs NRZ in St Albans

The most critical factor for subdivision potential is the planning zone. In St Albans, you'll encounter two main residential zones.

General Residential Zone (GRZ1): This is what you want. GRZ allows subdivision of existing lots into smaller parcels, construction of dual-occupancy dwellings, and multi-unit development up to three storeys (subject to council approval and ResCode standards). Minimum lot size after subdivision depends on the schedule, but generally you need 300-350sqm per new lot 1.

A 650sqm GRZ block can comfortably yield two lots. A corner block of 700sqm+ can sometimes yield three.

Neighbourhood Residential Zone (NRZ): More restrictive. NRZ typically limits development to two dwellings per lot, with a maximum height of two storeys (9 metres). The character overlay provisions mean setbacks are larger and site coverage is lower. You can still do dual-occupancy, but three-unit development is essentially impossible, and the design constraints add cost 2.

In St Albans, the GRZ/NRZ boundary runs roughly along certain north-south streets. Properties on one side of the line have significantly more development potential than properties 50 metres away on the other side.

I cannot stress this enough: check the zone before you make an offer. Two houses on the same street, same block size, same price — one is GRZ, one is NRZ. The GRZ block is worth $100K more in development value. If you buy the NRZ block thinking you can do a three-unit development, you've made a $100K mistake before you've even started.

Brimbank Council's planning scheme is available online. Our team checks it for every block we assess. It takes 30 seconds. Most buyers don't bother.

There's a third zone you'll occasionally encounter in St Albans: Activity Centre Zone (ACZ), which applies to pockets near the train station and main commercial strip. ACZ allows higher density and mixed-use, but the planning requirements are more complex and council scrutiny is much higher. For most investors, GRZ is the sweet spot — enough flexibility for subdivision or dual-occ without the regulatory overhead of ACZ.

The development streets: where the action is

Based on our street-level analysis, the St Albans pockets with the strongest development profiles share these characteristics:

Carinlea elevated pocket (south of Taylors Road)

• Predominantly GRZ1 zoning
• Block sizes typically 600-700sqm
• Relatively flat topography (critical for keeping construction costs down)
• Many blocks have side access via driveways wide enough (3+ metres) for rear lot vehicle access
• Active new-build activity confirms council is approving subdivision permits

This is our primary recommendation for buy-develop plays in St Albans. The evidence of council approval is visible — new townhouse pairs and dual-occ projects are going up on blocks that were single-dwelling five years ago.

East St Albans (between East Esplanade and Alfrieda Street)

• Mixed GRZ/NRZ — check individual blocks
• Larger blocks (some 700sqm+) from original 1950s-1960s subdivisions
• Good transport access to St Albans station
• Several corner blocks with dual street frontage (ideal for subdivision as each lot gets its own street address)

Corner blocks are worth a premium. A corner lot doesn't need a shared driveway or battle-axe access point. Each subdivided lot faces its own street. This simplifies planning applications, reduces construction cost, and increases the resale value of each individual lot 3.

"Corner blocks in St Albans are unicorns," says Joey Don. "When one comes up in GRZ zoning, we move within 24 hours. The development premium on a corner vs mid-block is $50K to $80K in finished lot value, but the purchase price difference is usually only $20K-$30K."

The dead-end streets: where subdivision fails

Now the equally important list — the blocks and pockets where development looks possible on paper but falls apart in practice.

Blocks with central sewer easements

A 1.83-metre-wide sewerage easement running through the middle of a block is a development killer. You must maintain a minimum 1-metre clearance on each side of the easement, which creates a 3.83-metre dead zone through the centre of the property. On a typical 18-metre-wide block, that wipes out 21% of the buildable width.

Easements running along the rear boundary are fine — they don't interfere with subdivision. But easements that cut diagonally or through the middle make dual-occupancy layouts mathematically impossible while meeting ResCode setback requirements 4.

We check every title plan for easement locations before recommending a purchase. This is non-negotiable in our due diligence process.

Blocks with restrictive covenants

Some older St Albans subdivisions carry "single dwelling" covenants — legal restrictions on the title that prohibit more than one residence. These covenants can be removed via VCAT application, but the process costs approximately $10,000 in legal fees and takes six months. For an investor on a tight timeline, that's a deal-breaker 5.

Blocks with insufficient width for dual access

ResCode requires any rear dwelling to have vehicle access independent of the front dwelling's driveway. The minimum driveway width for a single-vehicle accessway is 3 metres. If the block is too narrow (under 15 metres) or has an existing house positioned to block rear access, subdivision is physically impossible without demolishing the front home.

This rules out many of the narrower 500sqm blocks in older parts of St Albans. The blocks were originally subdivided for single homes in the 1960s, with 12-14 metre frontages. You can't fit a 3-metre driveway alongside a 12-metre-wide house.

Flood-prone areas (LSIO overlay)

Parts of western St Albans near Kororoit Creek carry Special Building Overlay (SBO) or Land Subject to Inundation Overlay (LSIO). These blocks face severe development restrictions, higher insurance premiums, and reduced resale value. Our rule is absolute: we never buy in a flood zone, regardless of price 6.

The numbers: what a subdivision actually costs in St Albans

For investors who've identified a suitable GRZ block, here's the realistic cost breakdown for a two-lot subdivision in Brimbank municipality.

Soft costs (planning and approvals):

• Town planner: $4,000-$6,000
• Survey and re-establishment: $3,000-$4,000
• Council planning application fee: $1,200-$1,500
• Engineering plans: $2,000-$3,000
• Legal fees (Plan of Subdivision registration): $2,000-$3,000
• Open space contribution (if applicable): 5% of site value or cash equivalent
• Total soft costs: approximately $15,000-$20,000 [7]

Hard costs (construction on rear lot):

• Dual-occupancy townhouse (3-bed, 2-bath, 150sqm): $280,000-$350,000
• Driveway and crossover: $8,000-$15,000
• Landscaping and fencing: $5,000-$10,000
• Total hard costs: approximately $300,000-$375,000

Total investment:

• Land acquisition: $700,000
• Soft costs: $17,500
• Hard costs: $337,500
• Total: approximately $1,055,000

Potential return:

• Existing house (on reduced lot ~350sqm): $550,000-$600,000
• New townhouse (on new lot ~300sqm): $600,000-$650,000
• Total end value: approximately $1,150,000-$1,250,000
• Gross profit: $95,000-$195,000

The variance is wide because construction costs in 2025 are volatile (material prices, labour shortages, council processing times). The conservative scenario still delivers a six-figure return on a 12-18 month project 8.

Alternatively, if you're not ready for full subdivision, the buy-hold-add-granny-flat strategy works here too. Purchase at $700K, add a $110K granny flat, collect $800+ per week in combined rent, and hold for capital growth while the surrounding suburb gentrifies. Less risk, slower return, but zero construction headache.

"People fixate on the gross profit from subdivision — $100K, $200K — but they forget holding costs," says Joey Don. "At 6% interest on a $700K property, you're paying $42K a year in interest alone. Every month of council delays costs you $3,500. Speed of execution is half the profit margin in small-scale development."

Practical advice for St Albans buyers in 2025

If you're serious about St Albans, here's my checklist.

1. Confirm GRZ zoning before inspecting. Do not rely on the real estate agent's assurance. Check Brimbank Council's planning maps yourself.
2. Order the title search early. Look for easement locations and restrictive covenants. A conveyancer charges $30 for a title search. That $30 could save you $100K.
3. Measure the frontage. If it's under 15 metres, dual-access subdivision is likely impossible. Bring a tape measure to the inspection or check on Google Maps.
4. Drive the streets at night. St Albans has huge variation between pockets. A block that looks fine at 11am might feel very different at 11pm. We do this for every property we assess.
5. Check flood overlays. VicPlan is free and shows every overlay. Takes two minutes.
6. Budget for the full development timeline: 6 months planning + 9-12 months construction = 15-18 months from purchase to completion. Factor in holding costs (interest, rates, insurance) for the full period.

St Albans isn't a suburb you buy blindly. It's a suburb you buy strategically, in the right pocket, on the right block, with the right zoning. Get those three elements right and the returns are compelling. Get any one of them wrong and you're stuck with a property that can't deliver on its potential.

We're actively buying in Carinlea right now. If the numbers make sense for your situation, this is the window.

One more thing worth mentioning: the Brimbank Council planning department has been processing subdivision applications in approximately 12 to 16 weeks as of early 2025. That's faster than most outer-suburban councils (Casey and Cardinia are running 20+ weeks). The faster processing time reduces your holding costs during the approval phase and gets you to construction sooner. For a time-sensitive development project, council processing speed is an underrated factor in suburb selection.

The February 2025 rate cut has also shifted developer sentiment. Several small-scale builders I speak with have told me they're prioritising western Melbourne for their next projects because land costs are lower than equivalent blocks in the southeast, and the infrastructure story is stronger. When builders start competing for sites, prices move quickly. The window for $700K 650sqm GRZ blocks in Carinlea is measured in months, not years.
