4 BEDROOM FAQ

4 Bedroom Granny Flat Questions

Answers about our four-bedroom floor plan, pricing and site requirements to help you plan your next step.

How much does a 4 bedroom granny flat cost in Victoria?

Our four-bedroom, two-bathroom base package starts from $189,999 including GST. Delivery, installation, foundations and utility connections are additional. Your final quote depends on site conditions, approval requirements and selected finishes.

Can I view the 4 bedroom granny flat floor plan?

Yes. View the floor plan on this page to see the four bedrooms, two bathrooms and central living and kitchen area. The layout places bedrooms on either side of the home, with shared living space in the centre.

How big is this four-bedroom design?

The design measures approximately 10m × 8m, giving an overall building footprint of about 80m². Final dimensions and the floor area used for approval purposes must be confirmed against the construction drawings.

How much backyard space do I need?

You need more than the building footprint alone. Setbacks, access, private open space, easements and service connections all affect whether the design fits. Total block size alone does not establish suitability.

Can I build a 4 bedroom granny flat in Victoria?

It may be possible, depending on your property and the final design. Bedroom count alone does not determine eligibility. The assessed floor area, zoning, overlays and applicable planning and building requirements need to be checked.

Does a 4 bedroom granny flat need council approval?

A building permit is normally required. Whether you also need a planning permit depends on the final design and your property's planning controls. An approximately 80m² footprint does not automatically establish an exemption, so confirm the approval pathway before committing.

Can I rent out a four-bedroom granny flat?

A lawfully approved dwelling can be considered for rental use, subject to applicable rental requirements. Four bedrooms may suit family tenants, but achievable rent depends on local demand, location, privacy, access and the finished property.

Should I choose a 3 or 4 bedroom granny flat?

Choose four bedrooms if the extra bedroom is useful for your household and your property can accommodate the larger design. Compare the bedroom sizes, shared living space, bathroom count and total project budget before deciding.
