Townhouse construction costs $350,000–$600,000+ per dwelling. A 4-unit project runs $1.5M–$3M. Buildana delivers 3–8 unit townhouse projects across 5 Western Sydney LGAs with fixed-price contracts, full DA management, and strata subdivision.
Multi-Dwelling Development That Delivers
Townhouse developments sit in the sweet spot between duplex and apartment — higher yield than dual occupancy, lower capital requirement and risk than a full apartment block. On blocks of 700m² or more across Western Sydney, a well-designed townhouse project can deliver 3–8 separate dwellings with Torrens or strata title subdivision.
Buildana builds townhouse projects for developers, sophisticated investors, and landowners with large blocks across Sydney — including Fairfield, Liverpool, Cumberland, Canterbury-Bankstown, and Blacktown LGAs. We handle the full scope: feasibility analysis, DA lodgement and management, architectural design, fixed-price construction, and strata subdivision through to title registration.
Every townhouse project starts with numbers. If the feasibility doesn't stack up, we tell you before any design work is committed. If it does, we lock in a fixed-price construction contract and deliver to schedule.

Townhouse Development Feasibility
The numbers that drive the decision — what makes a townhouse development profitable in Western Sydney:
Per-Dwelling Cost vs Sale Value
Construction cost per dwelling: $350,000–$600,000. End sale value per dwelling in Western Sydney: $650,000–$1,200,000. The margin between these two numbers — after land, approvals, holding costs, and selling costs — determines project viability.
Land Cost Ratio
Land should ideally represent no more than 40–50% of total project cost. In Western Sydney, development-zoned land at $800,000–$1,500,000 still supports profitable townhouse projects — unlike Eastern Suburbs or North Shore where land costs eliminate margins.
Target Return
Well-planned townhouse projects in Western Sydney target 15–25% developer margin on total project cost. Buildana provides full feasibility modelling including revenue projections, cost estimates, and sensitivity analysis before you commit.
