Approval Checks

SIZE & APPROVAL DIRECTION

Need More Than 60m²? We Can Design Larger Options Too.

For many owners, a 60m² granny flat is enough. But if your block, budget and approval pathway allow it, M Plus can also explore larger custom layouts around 60-100m².

Larger designs may suit families, long-term tenants or premium rental goals, but they usually need a more detailed planning review and may take longer to approve.

Standard

Standard 60m² Pathway

Best for faster projects, lower cost and simpler approval checks.

Larger custom

Larger 60-100m² Design

Better for more bedrooms, larger living areas or a more house-like feel.

Review first

Planning First, Design Second

We check zoning, overlays, access, setbacks and approval risk before pushing a larger layout.

COMFORT & PERFORMANCE OPTIONS

Passive House-Inspired Comfort

Passive House is about making a home warmer, quieter and more energy-efficient — through better insulation, better windows, less air leakage and smarter ventilation.

For custom granny flats, M Plus can discuss these upgrades early, before the design and budget are locked in.

COMFORT FIRST Not just how it looks. How it feels to live in.

Better comfort starts with the shell — insulation, windows, airflow and build details.

Better Insulation

Helps the granny flat stay warmer in winter and cooler in summer.

Better Windows

Reduces heat loss, glare, outside noise and summer heat gain.

Less Air Leakage

Careful detailing helps reduce drafts and wasted heating or cooling.

Smarter Ventilation

Fresh air and moisture control can be planned from the start.

Full Passive House certification is a specialist pathway. M Plus can discuss Passive House-inspired upgrades as part of a custom design, subject to budget, site conditions and approval requirements.

Custom Designs FAQ

Custom Granny Flat Designs FAQs

Clear answers before you choose a design or send your land details.

Can I build a granny flat larger than 60m² in Victoria?

Yes, larger designs may be possible depending on your land, zoning, overlays and approval pathway. A 90–100m² granny flat usually needs more planning review than a standard 60m² option.

Can I add Passive House features to my granny flat?

Yes, we can discuss Passive House–inspired upgrades such as better insulation, upgraded windows, airtightness detailing, ventilation strategy and solar-ready planning. Full Passive House certification needs specialist review.

Can the design suit family living?

Yes. For family use, we can lean into warmer finishes, softer styling, practical storage and a more comfortable everyday feel.

Can I choose the exterior look?

Yes. Exterior colour, cladding style, trims, window frame direction and roof tone can be reviewed depending on the selected design and availability.

Does a larger granny flat take longer to approve?

Usually, yes. Once the design goes beyond the simpler small second dwelling pathway, council or planning requirements may add time. That is why we check the land before finalising the design.

Is Passive House certification included?

Not by default. Certification is a separate specialist pathway. We can discuss whether it makes sense for your budget, site and long-term goals.

Will custom finishes change the price?

Some upgrades may affect the final quote. We confirm this after reviewing your preferred finish direction, selected base layout and site details.

What is the first step for a custom granny flat in Victoria?

Start with a land check. Once we know what can fit, we can recommend the right base layout and finish path.
