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 Brimbank 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 Ardeer 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.

Dual occupancy design in Ardeer

Dual occupancy is realistic for Ardeer homeowners with blocks in the right zone and of sufficient size. A two-lot subdivision typically requires a design meeting ResCode requirements, adequate frontage, and landscaping considerations.

The planning process is more involved than for extensions or granny flats, but the outcome, two separately titled properties, is substantially different financially.

RD Building Design carries out dual occupancy feasibility assessments at initial consultation. We review block size, zoning, and planning provisions before any design work, so you know whether the project is viable before committing.

Starting fresh in Ardeer

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 Brimbank 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.

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.

IN1Z

Planning overlays

Flood overlay

LSIO applies to areas near Kororoit Creek which runs through the suburb. Minimum floor levels and drainage requirements affect design on affected lots.

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

15km from Melbourne CBD. Nearest station: Ardeer.

Building design questions for Ardeer homeowners

Do I need planning approval to renovate in Ardeer?

Many renovations and extensions can proceed on a building permit alone under ResCode. Properties with heritage overlays or in special planning areas will generally need planning approval. RD Building Design determines this at the first consultation.

How long do permits take through Brimbank?

A building permit is typically assessed in about 10-20 business days. Planning permits through Brimbank generally take around 10-60 days. We set realistic expectations at the start of your project.

Can my Ardeer property support a granny flat?

Most NRZ and GRZ properties can add a secondary dwelling up to 60sqm without planning approval since Victoria's 2023 changes. The key constraints are site coverage, setbacks, and open space. RD Building Design confirms what your block allows.

Is my Ardeer block big enough for dual occupancy?

Under GRZ in Brimbank, dual occupancy typically needs at least 250sqm per resulting lot and appropriate frontage. RD Building Design reviews feasibility at the initial consultation before any design work.

Should I renovate or knockdown rebuild in Ardeer?

It depends on the condition of the existing house and the cost-benefit of renovation versus starting fresh. For non-heritage properties, knockdown rebuild is usually an option. RD Building Design can advise on which path suits your situation.

Where do I start if I want to build on my Ardeer property?

Start with a property assessment. RD Building Design reviews your block against the Brimbank Planning Scheme and provides a clear written summary of what you can build, including extensions, <a href="/backyard-buildings/granny-flats/">granny flats</a>, and dual occupancy potential.
