Curious about the difference between a building designer and an architect?

Two dwellings on one Altona Meadows block

Where zoning and lot size allow, dual occupancy turns one Altona Meadows 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 design for Altona Meadows 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 Hobsons Bay 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 Altona Meadows

Most extension projects in Altona Meadows 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.

What you can build in Altona Meadows

Planning controls and development potential under the Hobsons Bay Planning Scheme

Council

Hobsons Bay

Planning scheme

Hobsons Bay 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: Laverton.

This summary reflects general planning conditions for Altona Meadows 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 Altona Meadows homeowners

Do I need planning approval to renovate in Altona Meadows?

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 Hobsons Bay?

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

Can my Altona Meadows 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 Altona Meadows block big enough for dual occupancy?

Under GRZ in Hobsons Bay, 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 Altona Meadows?

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 Altona Meadows property?

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