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 Brookfield 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 Brookfield block

Where zoning and lot size allow, dual occupancy turns one Brookfield 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.

knockdown rebuild in Brookfield

When an existing Brookfield house has reached the end of its useful life, or when renovation costs exceed the value they would add, a knockdown rebuild gives you a home designed from scratch for your site, your household, and relevant planning controls.

The design can use the full site capacity allowed under the Melton Planning Scheme, oriented and configured for how you actually want to live.

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

Extending a home you plan to keep

Brookfield 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 Brookfield

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

35km from Melbourne CBD. Nearest station: Melton.

This summary reflects general planning conditions for Brookfield 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 Brookfield homeowners

Do I need planning approval to renovate in Brookfield?

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 Melton?

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

Can my Brookfield 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 Brookfield block big enough for dual occupancy?

Under GRZ in Melton, 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 Brookfield?

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 Brookfield property?

Start with a property assessment. RD Building Design reviews your block against the Melton 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.
