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 Kealba 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 potential in Kealba

For Kealba properties on lots with adequate size and frontage, dual occupancy can be a genuine option.

The permit pathway is more complex than a standard extension, but the result is two separately titled dwellings on a single block.

RD Building Design assesses dual occupancy feasibility as part of every initial consultation. We confirm whether the numbers work before any design commitment.

knockdown rebuild design for Kealba properties

A knockdown rebuild replaces the existing dwelling with a home designed specifically for the site. No inherited floor plan compromises, no structural limitations from the original building, improved thermal comfort.

The new design works within the Brimbank Planning Scheme to use the full allowable site capacity, oriented for the way your household actually lives.

RD Building Design manages the process from feasibility confirmation through to approved building permit drawings.

Building design for long-term homeowners in Kealba

Most extension projects in Kealba are driven by homeowners who intend to stay. The brief is personal: more space, better light, a layout that suits the household as it is now.

RD Building Design takes that seriously. We design around daily function, not spec appeal. Traffic flow, storage, the way rooms open to the outdoor spaces. The details that matter when you are living with the result.

Council

Brimbank

Planning scheme

Brimbank 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.

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 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

18km from Melbourne CBD. Nearest station: Keilor Plains.

This summary reflects general planning conditions for Kealba 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 Kealba homeowners

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

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 Kealba?

A building permit application is typically assessed in 10-20 business days. Where a planning permit is required first, Brimbank 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 Kealba 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 Kealba block?

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

Can I do a knockdown rebuild in Kealba?

If your property is not heritage-listed, a knockdown rebuild is usually viable. The replacement dwelling must comply with the Brimbank Planning Scheme for setbacks, site coverage, and neighbourhood character. RD Building Design confirms what the site allows before design begins.

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

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