How Much Land Do You Need to Build Townhouses in Melbourne?
Discover minimum land size requirements and best practices for townhouse developments in Melbourne. Gidaya Group explains zoning, setbacks & lot width
Townhouse development in Melbourne requires a strategic understanding of land dimensions, planning zones, and council regulations. If you’re wondering what the minimum land size for townhouses is — you’re not alone. It’s one of the most asked questions by property owners, investors, and developers.
In this guide, Gidaya Group breaks down the land size requirements and planning considerations for townhouse developments across Melbourne suburbs.
1. Is There a Legal Minimum Lot Size?
There is no state-wide mandated minimum lot size for townhouse construction in Victoria. However, your local council’s planning scheme — and zone overlays — play a major role.
Generally speaking:
300–400 sqm can support 2 townhouses in many residential zones
600+ sqm is typically required for 3–4 townhouses
Note: These figures are indicative only and subject to zoning, overlays, site slope, and existing dwellings.
2. Zoning & Density Controls
The zoning of your property determines the potential density:
General Residential Zone (GRZ): Most common for townhouse builds; allows multi-dwelling developments, usually 2–3 homes
Neighbourhood Residential Zone (NRZ): Typically restricts to 2 dwellings
Residential Growth Zone (RGZ): Allows greater density — often 3+ units or apartments
Tip: Gidaya Group offers zoning assessments to confirm your site’s development potential.
3. Lot Width Requirements
Lot width affects layout, access, and compliance:
Minimum 10–12m for side-by-side townhouses
Minimum 15m+ preferred for 3+ unit sites with shared driveways
Accessways must be at least 3m wide, with a 5.5m minimum crossover for shared driveways.
Gidaya Group’s designers use site modelling tools to validate site layout before drawings commence.
4. Site Shape & Slope
Oddly shaped or steeply sloped sites may reduce yield:
Irregular sites may cause design inefficiencies or reduced open space
Slopes above 6 degrees often require retaining walls or split-level designs
Gidaya Group assesses site constraints during feasibility to ensure realistic planning.
5. Council Setback Rules
Council setback requirements reduce the usable area of your site:
Front setback: Typically matches adjoining properties
Rear setback: 1m per 1m of height above 3.6m
Side setbacks: Increase with height under ResCode (Clause 55)
Understanding setbacks early avoids costly redesigns later.
6. Car Parking Requirements
ResCode mandates:
1 car space per 1–2 bedroom dwelling
2 spaces per 3+ bedroom dwelling (1 may be uncovered)
These car space requirements affect how many units your land can support. Narrow sites may limit yield.
7. Common Block Sizes for Melbourne Townhouses
Block Size (sqm) | Typical Capacity | Planning Zone Likely |
|---|---|---|
350–450 sqm | 2 units | GRZ / NRZ |
500–650 sqm | 2–3 units | GRZ |
700–850 sqm | 3–4 units | GRZ / RGZ |
900+ sqm | 4–6+ units | RGZ or Commercial Zone |
Note: Gidaya Group always confirms overlays before development feasibility is finalised.
