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 Wyndham 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 Werribee 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.

Heritage overlay design in Werribee

A heritage overlay does not mean you cannot build. It means the design needs to respond to the existing character of the property and its surroundings.

Extensions, secondary dwellings, and alterations in heritage areas proceed through planning permission. The design needs to sit comfortably alongside the original building without copying it.

RD Building Design works within Wyndham's heritage provisions and can advise at the outset what approvals your property requires under the Wyndham Planning Scheme.

Dual occupancy design in Werribee

Dual occupancy is realistic for Werribee 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.

Granny flat design and permits in Werribee

Victoria's 2023 planning changes simplified granny flat approvals. A secondary dwelling up to 60sqm is now permitted in most residential zones without a planning permit, provided it meets ResCode requirements for setbacks, site coverage, and private open space.

RD Building Design's Boxed Buildings range includes granny flat designs built from SIP panels: precision-manufactured kits that assemble on site in roughly half the time of conventional construction. We handle design and permit documentation; your builder manages assembly.

The key constraint on most Werribee blocks is site coverage. RD Building Design confirms what your specific block can accommodate before any commitment.

What you can build in Werribee

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.

NRZ Neighbourhood residential zone

Limits housing growth. Maximum two dwellings per lot in most cases. No apartment-style development. Protects established neighbourhood character.

RGZ Residential growth zone

Encourages higher density development. Apartments and multi-unit developments permitted. Fewer restrictions on building height and dwelling numbers.

Planning overlays

Heritage overlay

Heritage overlays apply to selected precincts around Werribee's historic town centre and older residential streets. The Werribee Park precinct (including Werribee Mansion) is a significant heritage site. Heritage assessment is required for works in affected residential areas.

Flood overlay

LSIO and SBO apply to areas along the Werribee River corridor. Properties near the river require site-specific flood assessment. The Werribee River has a significant flood history affecting low-lying areas of the town centre and surrounds.

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 many lots

GRZ or RGZ zoning on a significant proportion of properties. Lots meeting the minimum 300sqm-per-title threshold are common. Planning permit required.

Location

30km from Melbourne CBD. Nearest station: Werribee.

This summary reflects general planning conditions for Werribee 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 Werribee homeowners

Do I need a planning permit to extend my house in Werribee?

It depends on the work and your property's planning overlays. Many extensions can proceed directly to building permit under ResCode. Properties in heritage overlays or special planning areas usually require planning approval. RD Building Design assesses this at initial consultation.

How long does a building permit take in Werribee?

A building permit application is typically assessed in 10-20 business days. Where a planning permit is required first, Wyndham assessment typically takes 10-60 days. RD Building Design advises on realistic timelines at the start of every project.

Can I build a granny flat on my Werribee property?

Most residential lots zoned NRZ or GRZ can accommodate a secondary dwelling up to 60sqm without a planning permit under Victoria's 2023 provisions, subject to site coverage, setback, and open space requirements. RD Building Design confirms feasibility as part of an initial assessment.

Is dual occupancy viable on my Werribee block?

It depends on your lot size, zoning, and frontage. RD Building Design carries out dual occupancy feasibility assessments at initial consultation.

Can RD Building Design design extensions in a heritage area in Werribee?

Yes. RD Building Design has experience designing within heritage overlay areas under the Wyndham Planning Scheme. We can guide design to meet heritage guidelines while achieving what you want from the project.

How do I find out what I can build on my property in Werribee?

RD Building Design offers a property assessment that reviews your block against the Wyndham Planning Scheme and gives you a written summary of what is buildable: extension capacity, granny flat viability, dual occupancy potential, and any constraints.
