Title: Tips for Choosing the Right Granny Flat Design for Your Property

June 26, 2025

Adding a granny flat to your property is a smart investment — whether you're accommodating family, generating rental income, or increasing your home's overall value. But with so many styles, sizes, and features to choose from, selecting the right granny flat design can feel overwhelming.

No worries at all, we’ll walk you through the key tips to help you choose the perfect design to suit your lifestyle, budget, and long-term goals.

1. Understand Your Purpose
Before exploring different designs, clarify the main reason you’re adding a granny flat. Is it for:

a) Elderly parents or in-laws?
b) A teenager’s retreat?
c) A short-term rental?
d) A home office or studio?

Each purpose will influence the ideal layout. For example, if it's for aging parents, focus on single-level, accessible granny flat designs with wider doorways and a spacious bathroom. For rental income, a design with a full kitchen, privacy features, and separate access may be more appropriate.

2. Know Your Local Regulations
Every council or shire has its own rules when it comes to building granny flats in Australia. Ensuring your design complies with local regulations will save you time, money, and headaches down the road.

3. Match the Design to Your Block
The shape and slope of your land can determine which granny flat designs are suitable. For smaller or narrow blocks, consider: 20ft modular designs or Studio-style layouts.

If your land is sloping or has limited access, you may want to contact your sales manager so he can work with the transport team to assess your site and find the best solution for your terrain.

4. Think About Layout and Functionality
A smart layout makes even compact granny flats feel spacious and comfortable. Key features to consider:

a) Open-plan kitchen and living areas to maximise space
b) Natural lighting and ventilation for comfort
c) Built-in storage solutions
d) Private bedroom access for multi-occupant living
e) Covered verandas to extend the outdoor living space

Always look at sample floor plans and, if possible, visit a granny flat display model before making a final decision.

Choosing the right granny flat design is about more than just picking a floor plan — it's about creating a practical, comfortable, and compliant space that suits your lifestyle and adds real value to your property.
