At In House Granny Flats, every design starts with you. We take the time to understand your lifestyle, goals and block size to create a layout that fits perfectly.
If you already have a floor plan, we can refine it to suit your needs. Or we can customise one of our proven designs to match how you want to live.
From open-plan living areas to ensuite additions, every detail is shaped around you. Our team also helps you choose exterior finishes such as brick, cladding or a modern mix to bring your vision to life.
Architecturally Engineered
Make it custom
At In House Granny Flats, we know that every homeowner and every block is unique. Instead of forcing you into a fixed template, we give you the freedom to design a granny flat that truly fits your lifestyle and property.
Working directly with our in-house designer, you can personalise your floor plan, adjusting room sizes, layouts and features to match how you want to live. Because no two backyards are the same, your granny flat shouldn’t be either.
Need help choosing the perfect design for your block? Our in house team of design experts are readily available throughout the week to help plan your perfect granny flat.
