Working with RD Building Design

Rhys Davies Building Designer (DP-AD 43008) Adv.Dip. Building Design (Arch.), Registered Building Practitioner (Arch.) RD Building Design

RD Building Design is a registered practice covering Melton and Melbourne's wider western suburbs. We work exclusively on residential projects.

Your project is led by an experienced building designer throughout. No hand-offs, no junior staff running the detail.

For Kurunjang homeowners, that means clear advice, honest timelines, and permit drawings that do the job first time.

Building designer vs architect? Here is what the difference means for your project.

Two dwellings on one Kurunjang block

Where zoning and lot size allow, dual occupancy turns one Kurunjang property into two separately titled dwellings.

It is a more involved process than an extension or granny flat, but the financial outcome is a different category entirely.

RD Building Design reviews feasibility at the first consultation. We assess block size, zoning, and planning constraints before any design work begins.

Starting fresh in Kurunjang

Sometimes extending is not the right answer. When the existing house is past its useful life or the renovation cost would exceed the value it adds, a knockdown rebuild lets you design a home purpose-built for your site and your household.

A new design can take full advantage of the site capacity permitted under the Melton Planning Scheme, with no inherited compromises from the previous layout.

RD Building Design manages knockdown rebuild projects from initial feasibility through to building permit documentation.

Extending a home you plan to keep

Kurunjang 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 Kurunjang

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.

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

Medium to large (typically 500-800sqm+)

More design flexibility. Site coverage is rarely the binding constraint, allowing larger secondary dwellings and more generous setbacks.

Granny flat viability

Permitted up to 60sqm without a planning permit under Victoria's 2023 provisions. Most blocks have sufficient site coverage capacity for a well-sized secondary dwelling.

Dual occupancy

Viable on selected lots

Some GRZ zoning available, but NRZ dominates or lot sizes limit opportunities. Feasibility depends on specific block dimensions and frontage.

Location

36km from Melbourne CBD. Nearest station: Melton.

This summary reflects general planning conditions for Kurunjang 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 Kurunjang homeowners

Will I need a planning permit to extend in Kurunjang?

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 Kurunjang?

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 Kurunjang 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 subdivide my Kurunjang property for dual occupancy?

Dual occupancy requires adequate lot size, and sufficient frontage. RD Building Design assesses feasibility at the initial consultation stage.

Is a knockdown rebuild an option in Kurunjang?

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 Kurunjang 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.
