Making the most of a Cobblebank block

Smaller lots in Cobblebank leave less margin for error. An extension that pushes a setback, triggers overlooking, or reduces private open space beyond what the scheme allows will not get through permit.

RD Building Design resolves these trade-offs at design stage, not at permit assessment. We work on compact inner-west sites regularly and understand how the Melton Planning Scheme applies to tighter blocks.

Local planning knowledge in Cobblebank

The Melton Planning Scheme sets the rules, but understanding how Melton applies them takes experience beyond reading the document.

RD Building Design reads the Melton Planning Scheme as part of regular work. We know which overlays affect Cobblebank properties, how council interprets neighbourhood character requirements, and where the scheme gives flexibility worth using.

This knowledge shortens permit timelines and reduces requests for further information, which is the most common source of avoidable project delays.

What you can build in Cobblebank

Planning controls and development potential under the Melton Planning Scheme

Council

Melton

Planning scheme

Melton Planning Scheme

Predominant zones

GRZ General residential zone

Allows moderate housing growth. Dual occupancy viable on lots of 300sqm+ per resulting title. Medium density development permitted with a planning permit.

UGZ Urban growth zone

Applies to land on Melbourne's urban fringe identified for future residential development. Development is guided by precinct structure plans that set out lot sizes, density targets, and infrastructure requirements.

Planning overlays

No heritage, flood, or design overlays apply broadly to this suburb. Individual properties should still be checked for site-specific overlays.

Typical lot size

Small to medium (typically under 500sqm)

Site coverage is frequently the binding constraint. Extensions and secondary dwellings need careful positioning to stay under the 60% site coverage limit.

Granny flat viability

Permitted up to 60sqm without a planning permit under Victoria's 2023 provisions, but site coverage is likely to be the binding constraint. Many blocks can accommodate a secondary dwelling if existing building footprint allows.

Dual occupancy

Limited viability

Predominantly NRZ zoning or small lot sizes restrict dual occupancy to a small number of properties. Site-specific assessment essential.

Location

38km from Melbourne CBD. Nearest station: Cobblebank.

This summary reflects general planning conditions for Cobblebank as of 2025. Individual properties may have additional overlays or conditions. A property assessment confirms exactly what applies to your block.

Building design questions for Cobblebank homeowners

Will I need a planning permit to extend in Cobblebank?

That depends on the scope of the work and any overlays on your property. Many standard extensions go straight to building permit. Heritage or design overlay areas typically need planning approval first. We check this at your initial consultation.

What is the typical permit timeline in Cobblebank?

Building permits are usually assessed in around 10-20 business days. If a planning permit is needed, Melton generally takes about 10-60 days. RD Building Design provides realistic timelines at the outset of every project.

Is a granny flat possible on my Cobblebank block?

Under Victoria's 2023 reforms, a secondary dwelling up to 60sqm can be built on most NRZ and GRZ lots without a planning permit, provided site coverage, setback, and open space requirements are met. We assess this as part of an initial consultation.

Can I add a second storey in Cobblebank?

Usually, yes. The main considerations are the existing structure's load capacity and planning controls around overlooking, overshadowing, and character. RD Building Design checks both at concept stage.

Is a knockdown rebuild an option in Cobblebank?

For properties without a heritage overlay, knockdown rebuild is generally viable. The new dwelling must comply with the Melton Planning Scheme for setbacks, coverage, and character. We confirm feasibility before design starts.

How can I find out what is buildable on my Cobblebank property?

A property assessment from RD Building Design reviews your block against the Melton Planning Scheme and provides a written summary of development potential, including extension capacity, granny flat viability, and dual occupancy options.
