The Big Decision for Large Block Owners
You know your block has value. The question is how to extract the most from it. The two main paths are:
- Subdivide yourself — create separate lots and sell them individually
- Sell the whole block — let a developer handle the subdivision and development
Both can be profitable. The right choice depends on your financial position, risk tolerance, and timeline.
Option 1: Subdivide Yourself
The Process
- Engage a town planner and surveyor
- Lodge a Development Application with council
- Obtain approval and comply with conditions
- Register separate titles
- Sell individual lots on the open market
Typical Costs (Two-Lot Subdivision in Brisbane)
| Item | Cost |
|---|---|
| Planning and surveyor | $10,000-$15,000 |
| Council fees | $5,000-$8,000 |
| Infrastructure charges | $30,000-$50,000 |
| Civil works (driveway, services) | $25,000-$50,000 |
| Demolition (if required) | $15,000-$30,000 |
| Total | $85,000-$153,000 |
Typical Returns
Selling two vacant lots individually at retail prices to owner-builders or small developers.
Example — 1,000m² block in Kedron:
- Sell whole to developer: $850,000
- Subdivide into 2 x 500m² lots: $520,000 + $480,000 = $1,000,000
- Less subdivision costs: $110,000
- Net from subdividing: $890,000
- Premium over selling whole: $40,000
Timeline
12-18 months from start to selling both lots.
Risks
- Council may reject or modify the application
- Infrastructure charges may be higher than estimated
- Market conditions may change during the process
- You carry the project costs and risk
Option 2: Sell the Whole Block
The Process
- Get a development-focused appraisal
- Market to developers through a structured sale process
- Negotiate the best offer
- Settle and receive payment
Typical Costs
| Item | Cost |
|---|---|
| Agent commission (2-3% + GST) | $17,000-$30,000 |
| Legal fees | $2,000-$3,000 |
| Marketing | $3,000-$8,000 |
| Total | $22,000-$41,000 |

Typical Returns
A single sale at a development premium to one buyer.
Example — same 1,000m² block in Kedron:
- Sale to developer: $850,000
- Less selling costs: $30,000
- Net from selling whole: $820,000
Timeline
6-12 weeks from listing to unconditional contract.
Risks
- Limited to developer pricing (no retail premium)
- Developer may negotiate hard if they are the only buyer
- Conditional contracts carry settlement risk
Side-by-Side Comparison
| Factor | Subdivide Yourself | Sell Whole |
|---|---|---|
| Potential return | Higher (10-30% premium) | Lower but guaranteed |
| Timeline | 12-18 months | 6-12 weeks |
| Capital required | $85,000-$150,000 | Minimal |
| Risk level | Medium-High | Low |
| Complexity | High (council, engineers, surveyors) | Low (agent handles) |
| Best for | Experienced, patient, capital-rich | Risk-averse, time-poor |
The Hybrid Approach
There is a middle path: obtain Development Approval (DA) then sell the approved site.
This captures 60-70% of the subdivision premium without actually doing the civil works. A DA-approved site sells for 15-30% more than an un-approved site because the buyer eliminates planning risk.
| Approach | Net Return (Example) |
|---|---|
| Sell whole (no DA) | $820,000 |
| Sell with DA approval | $930,000 |
| Full subdivision and individual lot sale | $890,000 |
In this example, the hybrid approach actually delivers the best net result because it avoids the heavy civil works costs while capturing the approval premium.
Which Is Right for You?
Subdivide yourself if:
- You have $100,000+ in available capital
- You are patient (12-18 month timeline)
- You are comfortable managing consultants and the council process
- The potential premium justifies the risk and effort
Sell whole if:
- You want a clean, fast result
- You do not have capital for subdivision costs
- You are risk-averse
- The developer market is competitive in your area
Get the DA then sell if:
- You want a balance of premium and simplicity
- You have 6-12 months and $30,000-$50,000 for the approval process
- Your site has clear development potential with low approval risk

Frequently Asked Questions
Is it worth subdividing my block myself?
It can be, but the premium over selling whole is typically 10-30% and comes with 12-18 months of effort and risk. For many landowners, obtaining a DA then selling the approved site offers the best balance of return and simplicity.
How much does a Development Application cost?
A DA for a standard subdivision in Brisbane costs $20,000-$50,000 including planner, surveyor, engineering, and council fees. For more complex projects requiring traffic, acoustic, or environmental reports, costs can reach $80,000+.
What if council rejects my subdivision application?
If your application meets the planning scheme requirements, outright rejection is uncommon. More often, council issues an information request asking for additional detail or modifications. A good town planner can navigate these requirements.
