Development Feasibility Sydney — Know What Your Property Can Do Before You Commit
Most expensive development mistakes happen before construction starts. A proper feasibility prevents wrong site, wrong type, and wrong pathway.

Development feasibility studies cost $2,000–$8,000 and include GRV analysis, construction cost modelling, holding costs, profit margin analysis, and a clear go/no-go recommendation. Pre-purchase desktop assessments start at $1,500. Buildana provides feasibility analysis across 5 Western Sydney LGAs.
Know Before You Build — Real Numbers, Not Guesses
We study your block, overlays, services, orientation, and budget before you fall in love with the wrong plan. Buildana's development feasibility service provides a complete financial and planning analysis — Gross Realisation Value (GRV), construction cost modelling, holding costs, profit margin analysis, and a clear go/no-go recommendation.
Whether you're considering a duplex, townhouse project, boarding house, or commercial development — we give you the numbers before you make the decision. Our feasibility reports include sensitivity analysis (what happens if the market drops 10%?) and break-even calculations so you understand your risk exposure.
We work across Sydney — including Fairfield, Liverpool, Cumberland, Canterbury-Bankstown, and Blacktown LGAs. Each council area has different FSR, height, lot size, and DCP requirements that directly impact yield and feasibility — our local knowledge ensures accurate assessments.
- Gross Realisation Value (GRV) analysis with local comparables
- Construction cost modelling (±5–10% accuracy)
- Holding cost calculation (interest, rates, insurance)
- Profit margin and ROI analysis
- LEP and DCP planning overlay review
- Sensitivity analysis (±10% market movement)
- Break-even analysis
- Clear go/no-go recommendation
Case Studies — Feasibility in Action
Merrylands — Duplex Unlocked by July 2024 Reforms
A client approached Buildana to assess an R2 block in Merrylands previously assumed to be single-dwelling only. Our feasibility analysis confirmed the site was eligible for dual occupancy under the Low and Mid Rise Housing Policy (July 2024). The block met all lot size, frontage, and FSR requirements for a CDC-approved duplex — a development option the client didn't know existed.
Fairfield — Flood Overlay Strategy
A property near the Georges River in Fairfield sat within the flood planning area. CDC was not viable — but our feasibility assessment identified the DA pathway with a detailed flood compliance strategy. We coordinated with hydraulic engineers early, demonstrating habitable floor levels above the 1% AEP flood level, and proceeded to a successful DA determination.

Every feasibility engagement starts with a free initial assessment. We review your site address, zoning, and basic constraints to give you a preliminary view of what's possible — before any fee is charged.
Free Assessment Includes
- • Zoning confirmation and permitted uses
- • Key overlay checks (flood, heritage, bushfire)
- • Preliminary yield indication
- • Approval pathway recommendation (CDC or DA)
- • Next steps and scope for detailed assessment
Detailed Assessment (Paid)
- • Full LEP/DCP review with constraint mapping
- • Multi-scenario yield analysis
- • Indicative cost and revenue modelling
- • Written feasibility report
- • Recommended build type and project timeline

How It Works
From First Call to Final Key
You provide site details, development objectives, and budget parameters. We can work from an address alone — no architectural plans needed yet.
⏱We review LEP zoning, SEPP overlays, height limits, FSR, minimum lot sizes, and DCP controls affecting your site across the relevant council.
⏱Detailed construction cost estimates based on current market rates, council approval costs, consultant fees, and holding cost calculations (interest, rates, insurance).
⏱Determine the optimal number of dwellings, GRV based on comparable sales, and rental yield projections. Multiple scenarios compared side by side.
⏱Comprehensive report with financial summary, sensitivity analysis, risk assessment, and a clear go/no-go recommendation. No ambiguity — you know exactly where you stand.
