Curious about the difference between a building designer and an architect?

Making the most of a Tarneit block

Smaller lots in Tarneit 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 Wyndham Planning Scheme applies to tighter blocks.

Extending a home you plan to keep

Tarneit homeowners who extend are usually staying. That changes the design brief entirely. This is not about maximising a sale price. It is about making a home work better for the people living in it.

RD Building Design designs extensions around how households actually use their homes: how rooms connect, where natural light falls, how indoor and outdoor spaces relate to each other.

What you can build in Tarneit

Planning controls and development potential under the Wyndham Planning Scheme

Council

Wyndham

Planning scheme

Wyndham 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

25km from Melbourne CBD. Nearest station: Tarneit.

This summary reflects general planning conditions for Tarneit 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 Tarneit homeowners

Will I need a planning permit to extend in Tarneit?

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 Tarneit?

Building permits are usually assessed in around 10-20 business days. If a planning permit is needed, Wyndham 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 Tarneit 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 Tarneit?

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 Tarneit?

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

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

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